Table 1: Descriptions of Ports Page Columns provides descriptions of the columns on the ports page.

Box HostName

Table 1: Descriptions of Ports Page Columns
Column Description

Port ID

The port number is in <box ID>/<slot ID>/<port_ D> format in the CLI and H-VUE. For the GigaVUE TA Series slot ID is always 1 as they are not modular. For the GigaVUE‑HC1, GigaVUE-HC2, and GigaVUE-HC3, the line cards or modules are identified by the slot number.

In a standalone (default) configuration, box ID is always designated as 1 but can be changed through the CLI (it cannot be changed through H-VUE). In a cluster configuration, the box ID can vary.

Alias

Alias name of the port, if any.

Status

Health status of the port.

Note:   When a ports administrative status changes from 'enabled' to 'disabled', the health status of the administratively disabled ports remains in Green.
However, the health status of administratively disabled port is indicated as NA if Exclusion Rules are enabled for the ports that are admin disabled in the Alarms Page.
Refer to the 'Manage Alarms' section in the GigaVUE Administration Guide for more details.

Type

List the type of port such as network, tool, stack, inline network, inline tool, circuit, or hybrid.

You can set the port type through the Quick Port Editor or selecting the port on the Port page and clicking Edit. The port type is set by selecting the type in the Type field.

Speed

Current setting for the port’s speed.

Admin

Indicates whether the port is administratively enabled or disabled.

Force Link Up

Indicates the ‘force link up’ setting for the port. When enabled, this option forces connection on the optical port.

Ude

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

FEC

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.
• OFF—Disables FEC on the port.

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

Link Status

3. To enable the port, select Enable.
4. Click OK.

Each port can also be assigned an alias. Any port types set in the CLI or through the GigaVUE-FM APIs are reflected on this page. Any changes made in H-VUE are reflect in the CLI and responses to an API. For more information, refer to Port Aliases for port aliases and to the GigaVUE-FM REST API Reference in GigaVUE-FM User's Guide and the GigaVUE-FM Reference for APIs.

Configure Ports

From the Ports page, you can either configure or edit a specific port by selecting a port and clicking the Edit button on the Ports page or on the Quick Port Editor. Table 2: Port Configuration Options describes the options on the configuration page.

Table 2: Port Configuration Options
Field Description

Alias

The alias configured for this port, if any. 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 connection between, say, 1/1/x1 and 1/2/x4, you could connect Gb_In to Stream-to-Disk. Note that aliases can only be applied to single ports. They cannot be applied to groups of ports.

Port alias can be up to 128 characters long including special characters. Aliases are case sensitive.

Admin

Check to enable the port.

Type

Specifies whether the port is configured as an Inline Network port, Inline Tool port, Network port, Tool port, Stack port, Circuit port, or Hybrid port.

Speed

Specifies the speed for the selected port. For copper ports, you can click to change the speed as long as Auto Negotiation is disabled.

Duplex

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.

Auto Negotiation

Select to  enable auto-negotiation for the selected port. When auto-negotiation is enabled, duplex and speed settings are ignored. They are set through auto-negotiation.

For 1Gb fiber ports, auto-negotiation is not supported on GigaVUE-TA25.

Force Link Up

When enabled, this option forces connection on an optical port. Use this option when an optical GigaPORT tool port is connected to a legacy optical tool that does not transmit light. This option is not available for 10Gb capable ports with a 1Gb SFP installed.

Ude

When selected, this option indicates the port is unidirectional (UDE). When deselected (disabled), the port is bidirectional.

UDE is enabled by default.

Note: This option is available for GigaVUE-HC2 (CCv2), GigaVUE-HC3, GigaVUE-TA100, GigaVUE-TA100-CXP, and GigaVUE-200 platforms with 100Gb BiDi (QSB-512) transceiver. If used with passive taps, ports used for monitoring should be set to Network port with UDE enabled.

Important:If you clear the UDE check box, the laser will start to transmit, which may affect the remote connectivity.

FEC

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.

OFF—Disables FEC on the port.

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

Timestamp

Use the timestamp options when a GigaPORT-X12-TS line card is installed. For details about the GigaPORT-X12-TS line card, refer to the GigaVUE-OS-CLI Reference Guide. The timestamp options are as following:

Append Ingress—Use this option to add a timestamp to ingress packets a GigaPORT-X12-TS ports. This applies to ports x1..x12 when configured as network ports.

Strip Egress—Use this option to strip timestamps from egress packets.

Source ID Egress—Use this option to specify a custom source ID to be included in the timestamp appended by the GigaPORT-X12-TS. The source ID identifies the ingress port on the GigaVUE H Series node where the timestamped packet arrived.

The timestamp always includes a source ID. If you do not specify a custom value, the GigaPORT-X12-TS generates one automatically using the following formula:

(Box ID * 2048) + (Slot ID * 256) + Port Number

Important: Only apply the Strip Egress option to packets with time stamps appended. The strip egress feature strips the last 14 bytes of each packet regardless of whether a timestamp has been added.

VLAN Tag

Use VLAN tags to identify, differentiate, or track incoming sources of traffic. When the traffic reaches the tools or the maps, you can filter on the VLAN tags for the corresponding ports you want to measure.

Ingress port VLAN tagging is supported for IPv4 and IPv6 packet types, including non-tagged packets, tagged packets, and Q-in-Q packets. Ingress port VLAN tagging is not supported on inline network ports, hybrid ports, or on network ports that are connected via port-pairs. The same VLAN tag can be assigned to multiple network ports. However, each port can only have one VLAN tag. VLAN tagging is supported in a cluster.

• To add, VLAN IDs for a Port, enter the VLAN ID in this field.
• To modify, update the VLAN ID in this field and Save. It will take effect.
• To delete, remove any values for the VLAN ID in this field and Save. It will remove the VLAN Tag from this Port.

VLAN tags are only available on network ports.

Note:  On GigaVUE-TA25, 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.

Port Discovery

Select to enable discovery of neighbors associated with the port. Neighbor discovery is only available on network ports

Discovery Protocols

When port discovery is enabled, use the Discovery Protocol options to set up CDP or LLDP or both (All) on the port. The results are shown on the Ports Discovery page.

Buffer Threshold

Specifies the alarm buffer threshold on a port. You can specify the alarm buffer threshold in the Rx and Tx directions on network and stack type ports and in the Tx direction on tool type ports.

By default, the threshold is set to 0, which disables the threshold

Utilization Threshold

Sets the utilization percentage for this port at which the GigaVUE H Series node will generate high or low utilization alarms for the port. For more information about port utilization, refer to Monitor Port Utilization.

By default, the threshold is set to 0, which disables the threshold.

Lock Port

Restricts use of the 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.

You can optionally share a locked port by specifying users in the Lock shared with Users field or selecting users to share the lock with through their assigned roles. For more information about who to set lock sharing, refer to Managing Ports.

Tags

Select the required tag key and tag value to which the port must be associated to. The tag key and the tag value will be displayed depending on the role and the corresponding access rights of the user.

Ports Discovery

The Ports Discovery page displays the port neighbor information for each port that has discovery enabled. For each network port on which discovery is enabled, neighbor information is collected. Information for up to five of the most recent neighbors is retained for each port.

The following are limits on the amount of discovery information that is retained:

• For each port, discovery information for a minimum of two neighbors and a maximum of 20 neighbors is retained.
• For a chassis, discovery information for a maximum of 2K neighbors is retained.

Neighbor information is removed or replaced as follows:

• When the neighbor information expires due to the TTL.
• When the number of neighbors for the chassis reaches the 2K maximum and a new neighbor is discovered. In this case, the following can occur:
• If there are currently two or more discovered neighbors for a port, the newly discovered neighbor replaces the neighbor information for the least recently updated neighbor.
• If there are currently less than two discovered neighbors for a port, the newly discovered neighbor is added (actually exceeding the 2K limit to guarantee a minimum of two neighbors per port).

Note:  Aging (the discovery protocol time-to-live) determines how long neighbor information is valid.

For information about the discovery protocols and enabling port discovery, refer to Port Discovery

Statistics

The Statistics page displays the statics for all the ports on the node, providing the following information about a packets transmitted or received on a port:

Column Definition Notes

Octets (Rx/Tx)

The count of packets/bytes received and transmitted by this port.

Error packets are not transmitted, therefore they are not counted. Excludes undersize frames.

Octets/sec (Rx/Tx)

The count of packets/bytes received and transmitted by this port per sec.

Error packets are not transmitted, therefore they are not counted.

Unicast Packets
(Rx,/Tx)

The count of packets/bytes received and transmitted by this port.

Excludes multicast packets, broadcast packets, packets with FCS/CRC errors, MTU exceeded errors, oversize packets, and pause packets.

Non-Unicast Packets (Rx/Tx)

Total Non-unicast packets received or transmitted.

Packets/sec (Rx/Tx)

The rate which packets are received or transmitted.

 

Packet Drops (Rx)

Total Dropped Packets

Packets are dropped when a network port’s bandwidth is exceeded due to oversubscription. Packets are dropped when they reach the port but before they are sent out.

Discards (Rx/Tx)

Total received and transmitted packets discarded. This counter increments when a packet is discarded at the tool port due to egress port filter.

Discards are counted in the following cases:

Traffic arriving at a network port that is not logically connected using a map or map passall.

Map rules applied on a network port.

In packets on a tool port.

Pause frames.

Errors (RX/TX)

Total Error Packets Received or Transmitted.

Error packets include undersize, FCS/CRC, MTU exceeded, fragments, and oversize packets.

Excludes oversize packets without
FCS/CRC.

Packets larger than the MTU setting arriving on a network port are counted twice in the counter. So 1000 oversize packets would show up as 2000. This double-counting only happens with Oversize error packets.

Utilization (Rx/Tx)

Percentage of port utilization by packets received or transmitted
