port

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 for 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

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 GigaVUE-OS CLI. For example, instead of configuring a map from 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:  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.

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

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.

Note:  Configuring 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

Enables outer VLAN stripping on specified egress ports. The egress port type must be a 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.

Configures an ingress port VLAN tag, which is a number from 2 to 4000 that is added to a packet. The port must be a network or 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 to the E-tag mode.

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

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

The 100Gb ports that support 4x10Gb mode can operate at 40Gb speed with QSFP+ SR or PLR4 transceivers. When a parent port is configured in 4x10Gb, 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 4x25Gb 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 2x40Gb mode can operate at 40Gb speed with QSFP+ SR and LR transceivers. When a parent port is configured in 2x40Gb 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.

The following is an example of 4x10Gb mode:

(config) # port 1/1/c2 mode 4x10Gb

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 4x10Gb 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

Below are examples of valid port lists when 1/1/c2 is broken out:

1/1/c2x1..c2x4 includes 1/1/c2x1, 1/1/c2x2, 1/1/c2x3, 1/1/c2x4,

1/1/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

Below are examples of invalid port lists when 1/1/c2 is broken out:

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 2x40Gb mode example:

(config) # port 1/1/c3 mode 2x40Gb

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

or

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

The mode can be changed from 2x40Gb to 4x10Gb or from 4x10Gb to 2x40Gb without switching to none.

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

Configures port administration and physical parameters.

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

Autonegotiation Limitations:

Examples:

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

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

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

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

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:

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

For example:

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

Sets the line speed of a port as follows:

Sets the port speed in Mbps if auto-negotiation 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‑HC1-Plus, GigaVUE‑TA200 and on the following GigaVUE‑HC3 modules:

Note:  When AOC dual rate optics are used, the Link is down after changing the port speed from 40Gb to 100Gb between GigaVUE-HC3V2, PRT-HC3-C08, and GigaVUE‑TA25, GigaVUE‑TA25Edevices. To resolve this problem, first enable 40Gb speed in the GigaVUE‑TA25 and GigaVUE‑TA25E devices, then configure speed in the GigaVUE‑HC3 device.

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

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.

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

For example:

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

Configures drop or error threshold parameters in the rx direction.

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 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

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

Configures egress timestamp on a port.

For example:

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

Disables the ingress timestamp on the port.

For example:

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

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

Configures the L2GRE ID that is added to 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.

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 VXLAN 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. For proper functioning of the L2 MPLS Header Stripping feature, a 4-byte control word field is required between the MPLS label stack and the Layer 2 data. This information is needed to correctly identify the Layer 2 protocol across the MPLS network.

Configure the port to strip the MPLS Layer 3 header from incoming packets.

For example:

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

Configure the port to strip the MPLS Header from the L3 MPLS IPv4 (without options) packets. IPv4 without options has a standard 20-byte header for efficient routing.

For example:

(config) # port 1/1/d1 header-strip mpls-advanced ip4-wo-options

Configure the port to strip the MPLS header from the L3 MPLS IPv6 packets. The standard IPv6 header (40 bytes) follows the MPLS label stack and contains source and destination IPv6 addresses, flow label, and other fields.

For example:

(config) # port 1/1/d1 header-strip mpls-advanced ip6

Configure the port to strip the outer Ethernet and MPLS headers along with Control Word (CW) or Associated Channel Header(ACH) from the incoming L2 MPLS with CW or ACH packets. L2 MPLS with CW ensures packet sequencing and integrity for Layer 2 frames, while ACH enables Operations, Administration, and Maintenance (OAM) transport for network monitoring and management, especially in MPLS traffic.

For example:

(config) # port 1/1/d1 header-strip mpls-advanced l2-cw-ach

Configures the ZR+ optics transmit power offset in increments of 0.5 dBm. ZR+ optics transmit power ranges from -5 to +5 dBm in increments of 0.5.

For example:

(config) # port 1/1/d1 params zr-add-tx-opt-pwr 2.5

Configures the ZR+ grid frequency in GHz, ensuring alignment between devices. ZR+ grid frequency ranges from 191300 to 196200 GHz in increments of 100. The default value is 193100 GHz.

For example:

(config) # port 1/1/d1 params zr-frequency 192000
