port

Required Command-Line Mode = Configure

Use the port command to configure settings for ports on GigaVUE H Series line cards and modules, including aliases, port-filters, port parameters, and port types.

The port command has the following syntax:

       brief [port-list <port list>]
       discovery <cdp | lldp | all | disable>
       duplex <full>
       fec <cl91|cl74|cl108 | off>
       forcelinkup <disable | enable>
       gdp <enable | disable>
       speed <10 | 100 | 1000 | 10000 | 25000 | 40000 | 100000>
       ude <enable | disable>
       taptx <active | passive>
   ptp <enable | disable>

vlan <value>
       announce-interval <value>
       delay-req-interval <value>
       sync-interval <value>

tag-protocol-id <TPID value>
timestamp <append-ingress | source-id <0-65535> | strip-egress>

threshold [rx | tx] [drop | error] [count | percent] [value <value>]

l2gre-id <L2GRE identifier>

vxlan-id <VXLAN identifier>

header-strip <vxlan | mpls-l3>

The following table describes the arguments for the port command.

Argument

Description

port-id | port-alias | port-list

Specifies the ports on which to configure settings. Use one of the following:

●

port-id, port-alias, port-list—Specifies ports using the standard conventions described in Port Lists Definition in the GigaVUE‑OS.

alarm buffer-threshold <0-100%> | [rx <0-100%> | tx <0-100%]>

Specifies buffer alarm thresholds on a port, as a percentage from 1 to 100.

You can specify the alarm buffer threshold in the rx and tx directions for network and stack type ports and in the tx direction on tool type ports.

The default is 0, which disables the threshold.

For example:

(config) # port 2/1/x1 alarm buffer-threshold 50

(config) # port 2/1/x1 alarm buffer-threshold rx 60

high-utilization-threshold <0-100%>low-utilization-threshold <0-100%>

Specifies high and low utilization thresholds on a port, as a percentage from 1 to 100.

The utilization thresholds specify the value at which a utilization alarm will be generated for a port, either rising or falling. Alarms are reported to all configured SNMP trap destinations and recorded in the log file.

The default is 0, which disables the threshold.

For example:

●

Specifying high and low utilization thresholds for front-end ports:

(config) # port 1/1/x1 alarm high-utilization-threshold 70

(config) # port 1/1/x1 alarm low-utilization-threshold 20

●

Specifying high and low utilization thresholds for GigaSMART engine port:

(config) # port 1/1/e1 alarm high-utilization-threshold 70

(config) # port 1/1/e1 alarm low-utilization-threshold 20

alias <alias string>

Specifies an alias for a particular port. Aliases can be used in place of the numerical bid/sid/pid identifier required in many packet distribution commands in the CLI. For example, instead of configuring a map from, say, 1/1/x1 to 1/2/x4, you could create a map from Gb_In to Stream-to-Disk.

For example:

(config) # port 24/1/x1 alias myPort

Note that aliases can only be applied to single ports—they cannot be applied to groups of ports. To use an alias for a group of ports, use the tool-mirror feature.

assign role <user role> [level 1 | 2 | 3 | 4]

Specifies a required role that a user must be assigned in order to access the specified port. The access is granted at the specified permission level, as follows:

●

Level 1—Read-only access. Can view port configuration and statistics.

●

Level 2—Level 1 plus the capability to configure port-lock, lock-share, and all traffic objects except port-pair.

●

Level 3—Level 2 plus the capability to configure port params (such as administrative status of the port, speed, duplex, and autonegotiation), as well as port-pair.

●

Level 4—Level 3 plus the capability to change the port type.

For example:

(config) # port 24/1/x1 assign role Default level 1

buffer-index <<0-7> | low | default | high>

Configures a buffer-index value that allocates shared buffer space (memory) on specified ports to reduce oversubscription or to handle bursty traffic as follows:

●

0-7—Specifies a value for the buffer index.

●

low—Specifies a low buffer index, which is the same as a value of 3.

●

default—Specifies a default buffer index, which is the same as a value of 5.

●

high—Specifies a high buffer index, which is the same as a value of 7.

Use this parameter on tool and hybrid ports to reduce drops when the specified ports are oversubscribed or when traffic on the ports is bursty.

This parameter is supported on GigaVUE-TA10.

Note: It is recommended to configure the buffer-index value as low or default. Configuring a high buffer-index value causes packet drop in network ports (as there are no buffers for the incoming traffic).

Use the show buffer-index command to display the configuration of the buffer index on ports.

Examples:

(config) # port 1/1/x1 buffer-index low

(config) # port 1/1/x2..x5 buffer-index 2

comment <comment>

Specifies a unique text string that describes the port. Comments can be up to 128 characters. Comments longer than one word must be enclosed in double quotation marks.

For example:

(config) # port 24/1/x1 comment “My port”

egress-vlan strip

Enables outer VLAN stripping on specified egress ports. The egress port type must be tool or hybrid.

Use the show egress-vlantag command to display the configuration of outer VLAN stripping on egress ports.

Examples:

(config) # port 1/2/x1 egress-vlan strip

(config) # port 1/2/x2..x3 egress-vlan strip

If a port is configured for egress VLAN stripping, the port type cannot be changed until egress VLAN stripping is disabled. To disable outer VLAN stripping on specified egress ports:

(config) # no port 1/2/x1 egress-vlan strip

Note: Port level egress VLAN stripping is only supported if from/source ports are not on the same node as tool/hyrbid port with egress-vlan strip in double tag mode on GigaVUE‑HC1-Plus, GigaVUE‑TA25, and GigaVUE‑TA25E.

Refer to “Configuring Egress Port VLAN Stripping” section in the GigaVUE Fabric Management Guide for details.

filter rule
   add <drop <criteria> | pass <criteria>>
   delete <all | rule-id <rule ID>>
   edit rule-id <rule-ID> [drop <criteria> | pass <criteria>]

Manages filters on the specified egress port. Note that the filter argument is supported for tool, hybrid, circuit, and inline network ports. Network ports use maps to direct traffic.

Note: Port filters for inline network ports are not supported on GigaVUE TA Series devices.

Note: In the case of inline network LAG, the port filters must be applied on each of the inline network ports that are part of the inline network LAG.

The criteria available for egress port-filters is mostly the same as that used for filters—you can create pass or drop filters based on the same packet criteria available for maps. You can see the available criteria in the CLI by typing a command similar to the following:

(config) # port <egress port number> filter rule add pass ?

Refer to the “Port-Filters” section in the GigaVUE Fabric Management Guide for a description of the available filter criteria.

Note: You can configure egress port filters on a single port at a time. The filter argument is blocked when using the port command with multiple egress ports or port groups.

Examples:

The following tool port filter drops all packets with a VLAN ID between 100..200 from tool port 14/2/g40:

(config) # port 14/2/g40 filter rule add drop vlan 100..200

The following command passes only IPv6 traffic on tool port 14/2/g44:

(config) # port 14/2/g44 filter rule add pass ipver 6

Use the # show filter-resource command to view the maximum filter resources available and the filter resources used for a device.

Note: Egress port filters are supported on GigaVUE-TA25 and GigaVUE‑HC1-Plus, except that a) VLAN rules are not supported with port filters and b) either IPv4 or IPv6 type port filter rules are supported only if L2 circuit encapsulation tunnels or GS maps are used else both IPv4 and IPv6 rules are supported.

ingress-vlan-tag <2-4000>

Configures an ingress port VLAN tag, which is a number from 2 and 4000 that is added to a packet. The port must be a network or an inline network or hybrid type of port.

For example:

(config) # port 7/1/x1 ingress-vlan-tag 100

Note: On GigaVUE-TA25 and GigaVUE‑TA25E, ingress VLAN tagging is not supported on network ports associated with GSOP maps and GSOP maps are not supported on network ports configured with ingress vlan tag. This limitation is not applicable with E-tag mode.

lock [description <description>]

Restricts use of the specified port for only your user account as follows:

●

Users with the admin role can lock any port in the system. Users with the Default/Operator role assigned can only lock ports to which their account has been granted access.

●

Administrators can lock a port for another user by including the optional user <username> argument.

●

You can optionally share a locked port with the lock-share argument.

Refer to the “Setting Locks and Lock-Shares” section in the GigaVUE Administration Guide for details on how locks are used.

For example:

(config) # port 7/1/x1 lock

lock-share <user <username>>

Shares a locked port with another user account. For example:

(config) # port 7/1/x1 lock-share user operator

mode <none | 4x10G | 4x25G | 2x40G>

Configures the port breakout mode as follows:

●

none—Specifies no port breakout mode. This is the default mode for GigaVUE nodes.

●

4x10G—Specifies the 4x10G port breakout mode. This mode provides a 4 x 10Gb breakout option for 100Gb/40Gb ports. The 4x10G mode only applies to GigaVUE-TA40, GigaVUE-TA100, GigaVUE-TA200, GigaVUE-TA100-CXP, GigaVUE‑TA25, the PRT-HC3-C08Q08, PRT-HC3-C16, SMT-HC3-C05, and BPS-HC3-C25F2G modules on GigaVUE‑HC3, and the BPS-HC0-Q25A28 of Bypass Combo Module in GigaVUE‑HC2

Note: Starting in software version 5.5, GigaVUE-TA40 supports 4x10G breakout at port level. Port breakout mode in GigaVUE-TA40 is configured as follows:

24 out of the 32 ports provide 4x10Gb breakout support. The first 12 ports and the last 12 ports provide support for breakout functionality with 96 sub-ports operating as 10Gb ports

■

Ports q1 to q12 and q21 to q32 support breakout functionality

■

Ports q13 to q20 do not support breakout functionality

■

Port are named as q1x1….q1x4, q2x1...q2x4 (similar to other hardware platforms) to support the breakout functionality

●

4x25G—Specifies the 4x25G port breakout mode. This mode provides a 4 x 25Gb breakout option for 100Gb QSFP28 SR ports. The 4x25G mode only applies to GigaVUE-TA200 , GigaVUE‑TA25 and the PRT-HC3-C08Q08, PRT-HC3-C16, and SMT-HC3-C05 modules on GigaVUE‑HC3.

●

2x40G—Specifies the 2x40G port breakout mode. This mode provides a 2x40Gb breakout option for 100Gb/40Gb ports. The 2x40G mode only applies to the PRT-HC3-C08Q08 module on GigaVUE‑HC3.

For the BPS-HC3-C25F2G module on GigaVUE‑HC3, refer to the GigaVUE-HC3 Hardware Installation Guide.

Note: When there is a port breakout mode, the port command for the breakout port cannot be used with a “.. “ notation.

For Example:

To admin enable the port breakout mode:

(config) # port 1/1/c4x1 params admin enable

(config) # port 1/1/c4x2 params admin enable

The 100Gb ports that support 4x10G mode can operate at 40Gb speed with QSFP+ SR or PLR4 transceivers. When a parent port is configured in 4x10G, it can be broken out into four 10Gb ports, called subports. The subports will all have the same speed (10Gb). Subports have x1 to x4 appended to their port ID, for example, 1/1/c2x1.

The 100Gb ports that support 4x25G mode can be broken out into four times 25Gb ports, called subports. The subports will all have the same speed (25Gb). Subports have x1 to x4 appended to their port ID, for example, 1/1/c2x1.

The 100Gb ports that support 2x40G mode can operate at 40Gb speed with QSFP+ SR and LR transceivers. When a parent port is configured in 2x40G mode, it can be broken out into two 40Gb ports, called subports. The subports will all have the same speed (40Gb). Subports will have q1 to q2 appended to their port ID, for example, 1/1/c1q1 and 1/1/c1q2. The subports in the PRT-HC3-C08Q08 module on GigaVUE‑HC3 Control Card version 1 (CCv1) that function as stack ports must be of the same port type.

In general, subports created from port breakout modes can function as network, tool, or hybrid ports, as well as GigaStream port members, but they cannot function as stack ports. However, 10Gb stacking is supported only on GigaVUE‑TA25, GigaVUE-TA100 and PRT-HC3-C08Q08 on GigaVUE‑HC3 when ports are broken out into 4x10G mode.

Use break-out cables or breakout panels (PNL-M341 or PNL-M343). Refer to the respective Hardware Installation Guide.

The default mode is none.

Note: On GigaVUE-TA25 all port types are supported with break-out subports. Only C1, C5 ports support 4x10G, 4x25G break-out modes.

Note: Each port can only have one mode.

Examples of configuring parent ports and subports are listed on the next page.

mode <none | 4x10G | 4x25G | 2x40G> (continued)

The following is a 4x10G mode example:

(config) # port 1/1/c2 mode 4x10G

In this example, the subports will be: 1/1/c2x1, 1/1/c2x2, 1/1/c2x3, and 1/1/c2x4. Once the 1/1/c2 port (the parent port) is in the 4x10G mode, it is no longer available to be used in any configuration. For example if 1/1/c2 is used in a map, it will be rejected as an invalid port. Refer to the next page for rules for configuring parent ports and subports.

When a parent port, for example, 1/1/c2, is broken out, you cannot specify, for example, 1/1/c1..c4 in a port list, since 1/1/c2 will be rejected as an invalid port. To specify all the ports from 1/1/c1 to 1/1/c4 in a port list, including the subports, use the syntax as follows:

(config) # show port params port-list 1/1/c1,1/1/c2x1..c2x4,1/1/c3..c4

When 1/1/c2 is broken out, examples of valid port lists are as follows:

1/1/c2x1..c2x4 includes 1/1/c2x1,1/1/c2x2,1/1/c2x3,1/1/c2x41/1/c2x2..c4 includes 1/1/c2x2,1/1/c2x3,1/1/c2x4,1/1/c3,1/1/c41/1/c1..c2x3 includes 1/1/c1,1/1/c2x1,1/1/c2x2,1/1/c2x3

When 1/1/c2 is broken out, examples of invalid port lists are as follows:

1/1/c2..c2x3 1/1/c1..c3

The output of show commands will also display invalid ports. For example, when 1/1/c2 is broken out but 1/1/c1 and 1/1/c3 are not, the following is displayed:

(config) # show port params port-list 1/1/c1..c3 brief

Port      Type        Alias        Admin     ---------------------------------------------1/1/c2    network     -            disabled  ! Invalid port 1/1/c31/1/c4    network     -            disabled

The following is a 2x40G mode example:

(config) # port 1/1/c3 mode 2x40G

In this example, the subports will be: 1/1/c3q1 and 1/1/c3q2.

(config) # show port params port-list 1/1/c3q1..c3q2 brief

Port      Type        Alias        Admin     ---------------------------------------------1/1/c3q1    network     -            disabled  1/1/c3q2    network     -            disabled

To change the port mode back to none, either clear the mode or set it to none, as follows:

(config) # no port 1/1/c2 mode

(config) # port 1/1/c2 mode none

The mode can be changed from 2x40G to 4x10G or from 4x10G to 2x40G without changing to none.

Rules for configuring parent ports and subports are listed on the next page.

mode <none | 4x10G | 4x25G | 2x40G> (continued)

The following are rules for configuring parent ports and subports:

●

You can change the port mode from none to 4x10G or 2x40G if the parent port has port-level configuration (any of the parameters under the port command). However, you cannot change the port mode from none to 4x10G or 2x40G if there is an egress port filter configured on the parent port. Remove the filter first, then change the mode.

●

You can change the port mode from 4x10G or 2x40G to none if the subports have port-level configuration (any of the parameters under the port command). However, you cannot change the port mode from 4x10G or 2x40G to none if there is an egress port filter configured on the subport. Remove the filter first, then change the mode.

●

You cannot change the port mode from none to 4x10G or 2x40G if there is any traffic configuration on the parent port such as map, map-passall, map-scollector, port-pair, or tool-mirror. Remove the traffic configuration first, then change the mode.

●

You cannot change the port mode from 4x10G or 2x40G to none if there is any traffic configuration on the subport such as map, map-passall, map-scollector, port-pair, or tool-mirror. Remove the traffic configuration first, then change the mode.

●

You cannot configure any parameters on a parent port if the port is broken out into subports. For example, if you try to configure port 1/1/c1 when it has subports 1/1/c1x1..c1/x4, the following error message is displayed:

(config) # port 1/1/c1 type tool% Invalid port '1/1/c1'.

●

You cannot configure any parameters on a subport if the port is not broken out into subports. For example, if you try to configure port 1/1/c2x1 when 1/1/c2 is not broken out, the following error message is displayed:

(config) # port 1/1/c2x1 type tool% Invalid port '1/1/c2x1'.

●

In general, subports cannot be configured as stack ports. An error message is displayed as follows:

(config) # port 1/1/c1x4 type stack% Port 1/1/c1x4 is not parent port and does not support type stack

(config) # port 5/4/c3q1 type stack

% Port 5/4/c3q1 is not parent port and does not support type stack

●

QSFP+ LR transceivers do not support 4x10G port breakout. If you try to breakout a port with QSFP+ LR transceiver, an error message is displayed as follows:

% Port 1/1/c3 does not support breakout mode

●

For the BPS-HC3-C25F2G module on GigaVUE‑HC3, if the default inline network (default_inline_net) is modified, you cannot change the port mode from none to 4x10G or from 4x10G to none. An error message is displayed as follows:

(config) # port 2/2/c1 mode none% Port '2/2/c1x1' is being used by:1) inline-network default_inline_net_2_2_1_1 (not default values)

params

Configures port administration and physical parameters.

admin <disable | enable>

Administratively enables or disables ports. Use the show port params command to see the administrative status of ports.

For example:

(config) # port 7/1/x1 params admin enable

autoneg <disable | enable>

Enables or disables auto-negotiation for a port. When auto-negotiation is enabled, duplex and speed settings are ignored.

Autonegotiation Limitations:

Autonegotiation is always disabled for for 10GB, 25GB, 40Gb and 100Gb ports.

For 1Gb speeds over copper, auto-negotiation must be enabled, per the IEEE 802.3 specification.

For 1Gb fiber ports, auto-negotiation is not supported on Gigamon Platforms..

Examples:

(config) # port 7/1/x1 params autoneg disable

(config) # port 1/2/g7 params autoneg enable

discovery <cdp | lldp | all | disable>

Configures port discovery options on network, tool, or circuit type ports, as follows:

●

cpd—Enables CDP port discovery.

●

lldp—Enables LLDP port discovery.

●

all—Enables both CDP and LLDP port discovery protocols.

●

disable—Disables port discovery.

For example:

(config) # port 7/1/x1 params discovery cdp

Discovery is disabled by default. To enable discovery, configure one or more protocols.

Refer to the “Port Discovery with LLDP and CDP” section in the GigaVUE Fabric Management Guide.

duplex <full>

Specifies the port's duplex configuration. Only full duplex is supported.

Starting in software version 5.2, half duplex support is removed from all GigaVUE nodes. If half duplex was configured in a previous software version, it will remain intact following the upgrade to 5.2 or higher release. Update to full duplex, if required.

For example:

(config) # port 7/1/x1 params duplex full

fec <cl91|cl74|cl108| off>

Configures forward error correction (FEC) on the port to ensure error-free traffic over long distance. The values are:

●

cl91—Enables FEC on the port.

●

cl74— Enables FEC on the port.

●

cl108 — Enables FEC on the port for GigaVUE‑TA25 and GigaVUE‑TA25E.

●

off—Disables FEC on the port.

Note: This option is available only on 25Gb and 100Gb transceivers.

For example:

(config) # port 7/1/x1 params fec cl91

forcelinkup <disable | enable>

Forces connection on an optical port. Use this option when an optical tool port is connected to a legacy optical tool that does not transmit light.

Forcelinkup is available as follows:

●

Available for tool ports.

●

Available for optical 40/100/400Gb network ports.

●

Not available for 10Gb-capable ports with a 1Gb SFP installed. 10Gb-capable optical tool ports only support forcelinkup when a 10Gb SFP+ is installed.

●

Not available on 100Gb ports with CFP2 transceivers.

Use forcelinkup on a tool port and optical 40/100/400Gb network ports. The forcelinkup status will be on when:

●

the tool port and network port are administratively enabled.

●

forcelinkup is enabled, with or without a transceiver or cable for the tool port.

●

the tool port link is up.

●

forcelinkup is enabled, with a transceiver or cable for the network port.

●

the network port link is up for 40/100/400Gb links.

For example:

(config) # port 7/1/x1 params forcelinkup enable

gdp <enable | disable>

Enables or disables the Gigamon discovery (GDP) on the port.

●

enable—Enables Gigamon discovery (GDP) on the port.

●

disable—Disables Gigamon discovery (GDP) on the port.

Gigamon discovery is disabled on the port by default.

Gigamon discovery cannot be enabled on inline-tool and inline-network type ports.

speed <10 | 100 | 1000 | 10000 | 25000 | 40000 | 100000>

Sets the line speed of a port as follows:

●

10—10Mbps

●

100—100Mbps

●

1000—1Gbps

●

10000—10Gbps

●

25000—25Gbps

●

40000—40Gbps

●

100000—100Gbps

Sets the port speed in Mbps if autonegotiation is off.

Examples:

(config) # port 1/1/x1 params speed 10000

(config) # port 7/1/c1 params speed 40000

Use 40000 and 100000 to change the port speed of each inline network port pair (c1/c2 or c3/c4) on the BPS-HC3-C25F2G module on GigaVUE‑HC3. You only need to configure one port in each pair.

Use 25000 to change the port speed on GigaVUE-TA25E, GigaVUE-HC1P ,GigaVUE-TA200 and on the following GigaVUE‑HC3 modules:

●

PRT-HC3-X24

●

BPS-HC3-C25F2G

●

BPS-HC3-Q35C2G

●

BPS-HC3-C35C2G

●

PRT-HC1P-Q04X08

●

HC1P-C04X08

ude <enable | disable>

Indicates whether the port is enabled for unidirectional (Ude) or bidirectional traffic. Enabled means Ude; Disabled means bidirectional.

For example, you can enable the port and disable unidirectional ethernet in a single line or separately:

(config) # port 7/1/x1 params admin enable ude disable

-or-

(config) # port 7/1/x1 params admin enable

(config) # port 7/1/x1 params ude disable

taptx <active | passive>

Opens or closes the copper TAP port relay. Active closes the port relay. Passive opens the port relay.

For example:

(config) # port 7/1/x1 params taptx active

ptp

Enables or disables PTP configuration on a port.

For example:

(config) # port 1/1/c1 ptp enable

(config) # port 1/1/c1 ptp disable

vlan <value>

Configures the PTP Port VLAN wihin the range 2-4000.

For example:

(config) # port 1/1/x1 ptp vlan <35>

Use the command show vlan-resource to identify available VLAN resources. Refer to show section for more information.

announce-interval <value>

Configures the time interval, in seconds on a logarithmic scale, between PTP announce messages in the port. The valid range is between -3 and 4 log seconds. The default is -3.

For example:

(config) # port 1/1/c1 ptp announce-interval -3

delay-req-interval <value>

Configures the minimum interval allowed between PTP delay request messages. The valid range is between -7 and 0 log seconds. The default is -4.

For example:

(config) # port 1/1/c1 ptp delay-req-interval -4

sync-interval <value>

Configures the time interval between PTP synchronization messages on the port. The valid range is between -7 and 0 log seconds. The default is -4.

For example:

(config) # port 1/1/c1 ptp sync-interval -4

threshold

<rx> [drop | error] [count | percent ] value <value>

Configures drop or error threshold parameters in rx direction.

<tx> [drop | error] [count | percent ] value <value>

Configures drop or error threshold parameters in tx direction.

tag-protocol-id <TPID value>

Configures a TPID value for the ingress port VLAN tag. The default value of TPID is 0x8100 and other supported values are 0x9100 and 0x88a8.

If tag-protocol-id is configured without configuring ingress-VLAN-tag on the port, the CLI displays the following error message.

"Ingress Vlan Tagging is not enabled on Port <port>; Configure ingress-vlan-tag before configuring tag-protocol-id"
Upon unconfiguring ingress-vlan-tag on a port, the tag-protocol-id configured on the respective port would be unconfigured (set to the default value: 0x8100).

For example:

(config) # port 1/1/x3 tag-protocol-id 0x88a8

timestamp <append-ingress | source-id <0-65535> | strip-egress>

Configures timestamping options.

For example:

(config) # port 7/1/x1 timestamp append-ingress

(config) # port 7/1/x1 timestamp source-id 500

timestamp

ingress insert

Configures ingress timestamp on a port.

Note: Use these arguments for GigaVUE-TA200 devices.

Note: Use the show timestamp brief command to display the PTP based timestamp information.

For example:

(config) # port 1/1/c3 timestamp ingress insert

ingress source-id <value>

Specifies a unique ID for the ingress timestamp. The packets that ingress the port will be timestamped with this unique source ID. The source ID enables you to identify the port on which the timestamp is applied.

For example:

(config) # port 1/1/c3 timestamp ingress source-id 113

egress insert

Configures egress timestamp on a port.

For example:

(config) # port 1/1/c2 timestamp egress insert

egress source-id <value>

Specifies a unique ID for the egress timestamp. The packets that egress the port will be timestamped with this unique source ID. The source ID enables you to identify the port on which the timestamp is applied.

For example:

(config) # port 1/1/c2 timestamp ingress source-id 112

ingress disable

Disables the ingress timestamp on the port.

For example:

(config) # port 1/1/c3 timestamp ingress disable

egress disable

Disables the egress timestamp on the port.

For example:

(config) # port 1/1/c2 timestamp egress disable

tool-share role <user role>

Designates a tool port as available for tool-to-tool pass-alls (tool-mirrors) with the specified roles. For example:

(config) # port 7/1/x1 tool-share role admin

Specifies a port as a hybrid, inline-network (input), inline-tool (output), network (input), tool (output), stack, or circuit port. For example, the following command configures port g2 in slot 2 on box 1 as a tool port:

(config) # port 1/2/g2 type tool

All ports on GigaVUE H Series line cards or modules are available as network and tool ports.

Stack ports are supported at speeds of 10Gb, 40Gb, and 100Gb. However, stack ports are not supported on SFP-531 optics (10GBASE-T) and SFP+ 531T optics..

A hybrid port is a physical port that has a dual function as a network port and as a tool port. Refer to the “Working with Hybrid Ports” section in the GigaVUE Fabric Management Guide.

The inline-network and inline-tool type of ports can only be configured on GigaVUE HC Series nodes. Refer to the “Configuring Inline Bypass Solutions” chapter in the GigaVUE Fabric Management Guide.

Circuit ports are used to send or receive traffic that is tagged with a circuit ID. For more information, refer to the “Circuit Ports” section in the GigaVUE Fabric Management Guide.

l2gre-id <L2GRE identifier>

Configures the L2GRE ID that is added in the L2GRE group created for a specific device . The ID configured for the network port overrides the ID configured at the chassis-level.

For details about the CLI command used to configure the L2GRE group, refer to Configure L2GRE Group.

For example:

(config) # port 7/1/x1 l2gre-id 400

Note: You cannot specify both L2GRE ID and VXLAN ID for a network port.

vxlan-id <VXLAN identifier>

Configures the VXLAN ID that is added in the VXLAN group created for a specific device . The ID configured for the network port overrides the ID configured at the chassis-level.

For details about the CLI command used to configure the VXLAN group, refer to Configure VXLAN Group.

For example:

(config) # port 7/1/x1 vxlan-id 300

Note: You cannot specify both L2GRE ID and VXLAN ID for a network port.

header-strip <vxlan | mpls-l3>

Enables the header stripping functionality on the specified network or hybrid port.

For example:

(config) # port 1/1/c1 header-strip vxlan

(config) # port 1/1/c1 header-strip mpls-l3

Note: You cannot enable both VXLAN header stripping and MPLS header stripping on the same port. For more information, refer to the "VXLAN Header Stripping – Rules and Notes" and "MPLS Header Stripping – Rules and Notes" sections in the GigaVUE‑FM User's Guide.

Note: The command mpls-l3 enables the L2 and L3 MPLS Header Stripping functionality on the GigaVUE-TA400 device.
