Table 9. show port table Command Output Descriptions
Field Description

Port

Specifies the chassis slot and port numbers (<slot>/<port>) for all installed line cards.

Role

The communication role played by this port.

  • Mgmt: Port has been designated for remote management access.

  • Srvc: Port handles subscriber traffic.

Type

The card type descriptor.

Admin

Indicates whether or not the card has been configured for use via software. If it has been configured, Enabled will be displayed. If not, Disabled will be displayed.

Oper

The operational state of the card – Up or Down.

Link

The link status – Up or Down.

State
The operational mode of the card that the port belongs to. The card can be in one of the following modes:

  • Active: Indicates that the card is an active component that will be used to process subscriber data sessions.

  • Standby: Indicates that the card is a redundant component. Redundant components will become active through manual configuration or automatically should a failure occur.

  • Offline: Indicates that the card is installed but is not ready to process subscriber data sessions. This could be because it is not completely installed (for example. the card interlock switch is not locked). Refer to the Installation Guide for additional information.

Pair

Interface slot/port number of LAG peer port.

LAG Port Status:
  • LA+ = Port is actively used for distributing
  • LA- = Port failed to negotiate LACP
  • LA~(tilde) = Port negotiated LACP but another peer was selected
  • LA*(asterisk) = Port is (re)negotiating LACP
  • LA# = Port has been gone down because the min-link criteria is not met (ASR 5500 only)

Redundant

Interface slot/port number of redundant LAG peer port.

Untagged:

 Indicates the administrative, operational, link and active/standby states of an untagged (non-VLAN) port.

Tagged: VLAN <vlan_id>

 Indicates the administrative, operational, link and active/standby states of a VLAN port.
