show ports

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


Displays port summary statistics.

Syntax Description


Specifies one or more ports or slots and ports.


Specifies an 802.1Q or 802.1ad tag value.


Specifies a static snapshot of the data.

refresh Specifies a continuous refresh of output.



Usage Guidelines

Use this command to display the port number, display string, and some of the port states in tabular form.

The VLAN name is displayed only if that port contains a single VLAN. If the port contains more than one VLAN, then the number of VLANs is displayed.

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

The default display string for Integrated Application Hosting (IAH) dedicated ports on ExtremeSwitching X465 series switches is “Insight” to indicate that these are to be used for virtualization. On X465-24MU and and X465-24XE switches, the dedicated ports are 33–34; on X465-24MU-24W, and X465i-48W switches, the dedicated ports are 57–58. You can change this display string (configure ports port_list display-string string ). If you unconfigure the display string, it is reset to “Insight”.


The following command displays information on ports 2, 3, and 12 on a switch:

Restricted optics will show similarly to unsupported optics (!) in the show ports command by use of a ‘$‘.  Additionally, when a 3rd-party license has been installed, previously restricted optics are shown using a ‘%‘, because those optics are un-restricted by means of the license. Here is an example output:
