show port information

show port {mgmt |port_list | tag tag} information {detail}

Description

Displays detailed system-related information.

Syntax Description

mgmt Specifies the management port.
port_list Specifies one or more ports of slots and ports.
tag Specifies an 802.1Q or 802.1ad tag value.
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.
