Display Similar Output to the Cisco IOS "show interface status" Command

 

For SLAX version 1.0 and higher, you can use the show-interface-status script to mirror the Cisco IOS command "show interface status".

 

This script displays the logical-interface name, status, VLAN members, speed, and duplex of the Ethernet switching-interfaces on the system. It provides similar output to the Cisco IOS command "show interface status".

 

A command-line argument exists (interface) that filters the exact interface. Error checking is performed based on the interface you enter.
