detail Specifies detailed port information.

Default

N/A.

Usage Guidelines

This command displays information, including the following:

  • Port number
  • Port configuration
    • Virtual router
    • Type of port
    • Admin state
    • Link state and speed
    • Link Up/Down Transition
    • VLAN (Virtual LAN) configuration
    • STP (Spanning Tree Protocol) configuration
    • Trunking, or load sharing
    • EDP (Extreme Discovery Protocol)
    • ELSM (disabled; or if enabled, the ELSM link state is shown as well)
    • Load balancing
    • Learning
    • Link-flap detection status
    • Egress flooding
    • Jumbo frames
    • Link port up/down traps
    • Port isolation status
    • QoS (Quality of Service) profiles
    • VMAN status
    • Smart Redundancy status
    • SRP status
    • Additional platform-specific information
    • Port partition information
    • IEEE Forward Error Correction (FEC) Clause 74 or 91 modes status

If you do not specify a port number, range of ports, or tag value, detailed system-related information is displayed for all ports. The data is displayed in a table format.

The tag value may be associated with either a VMAN or a VLAN.

This status information may be useful for your technical support representative if you have a network problem.

The detail parameter is used to provided more specific port information. The data is called out with written explanations versus displayed in a table format.

Note

Note

The keyword detail displays slightly different information depending on the platform and configuration you are working with.

The link filter counter displayed with the detail keyword is calculated at the middle layer on receiving an event. The link filter up indicates the number of link transitions from down to up at the middle layer filter.

History

This command was first available in ExtremeXOS 10.1.

Information on ingress rate shaping was added in ExtremeXOS 11.0.

Network Login, Smart Redundancy, and rate limiting were added in ExtremeXOS 11.1.

Information on unicast, multicast, and broadcast flooding; the Port not present parameter; and autopolarity status were added in ExtremeXOS 11.2.

The netlogin parameters were added in ExtremeXOS 11.3.

The output command was modified in ExtremeXOS 12.1 so that when learning is disabled with the disabled learning port command, a new w flag appears in the output.

Link Ups and Link Downs information was added to the output and the tag value was added to the command syntax in ExtremeXOS 12.4.4.

Industrial Temperature detail added to Type field in ExtremeXOS 15.1.2.

Note

Note

The Industrial Temperature detail is only displayed only when detail is used. Without it, the output is compressed and the optic type is not displayed.

The show output was enhanced to display the SNMP ifMib ifAlias accessible string size information.

The show output was updated to include the current status of non-Extreme optical devices in ExtremeXOS 15.4.

Link-flap detection information was added in ExtremeXOS 22_1.

Available Port Partitions was added to show port speed licensing information for ExtremeSwitching X870-96x-8c switches in ExtremeXOS 22.2.

IEEE Forward Error Correction (FEC) Clause 74 or 91 modes status was added in ExtremeXOS 22.3.

MACsec information was adde in ExtremeXOS 22.5.
