show ports configuration

show ports {mgmt | port_list | tag tag} configuration {no-refresh | refresh}

Description

Displays port configuration statistics, in real time or snapshot.

Syntax Description

mgmt

Specifies the management port.

port_list

Specifies one or more ports or slots and ports.

tag

Specifies an 802.1Q or 802.1ad tag value.

no-refresh

Specifies a static snapshot of data.
refresh Specifies a continous refresh of output.

Default

Real-time statistics.

Usage Guidelines

If you do not specify a port number, range of ports, or tag value, configuration statistics are displayed for all ports. If you specify the no-refresh parameter, the system displays a snapshot of the data at the time you issue the command.

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.

This command displays port configuration, which includes:
  • Virtual router.
  • Port state.
  • Link state.
  • Autonegotiation information.
  • Link speed.
  • Duplex mode.
  • Flow control.
  • Load sharing information.
  • Link media information.
    Note

    Note

    On 10 Gbps ports, the Media Primary column displays NONE when no module is installed, and SR, LR, or ER depending on the module installed when there is one present. Combination ports display Autonegotiation, Link speed, and Duplex mode information only for the current primary medium.

Example

The following command displays the port configuration for all ports on a switch:

# show port configuration no-refresh

This command was updated to include flags that indicate the summary status of a non-Extreme optical device in ExtremeXOS 15.4.

The refresh keyword was added in ExtremeXOS 16.1.

Flag (L) to show port disabled due to lack of port speed license (applies to ExtremeSwitching X870-96x-8c switches, which are not supported in release 32.1).

Flag (#) to show that LRM/MACsec adapter is connected to a port was added in ExtremeXOS 30.1.

Mismatched port compatility indication was added in ExtremeXOS 31.3.
