Syntax Description

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.

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.
