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
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 on Summit X460, X480, and X670 series switches 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:

The following command displays the port configuration for slot 2, port 2 on a modular switch:

show ports 2:2 configuration

Following sample output includes flags that indicate the summary status of a non-Extreme optical device. "Licensed" means the optics license is installed (the 40G+ device is unrestricted, but still unsupported). "Unsupported" means the non-Extreme device is unsupported by Extreme, but is unrestricted because it does not require a license (1G/10G). "Restricted" means the non-Extreme 40G+ device will be restricted because no optics license is installed.
