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 (Virtual LAN).

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

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 Summit family switch:
