Displays configured system interfaces and their status

Supported in the following platforms:

Syntax

show interface {<INTERFACE-NAME>|brief|counters|ge|me1|port-channel|pppoe1|switchport|
vlan|wwan1}
show interface {<INTERFACE-NAME>|brief|counters|ge <1-4>|me1|port-channel <1-2>|
pppoe1|switchport|vlan <1-4094>|wwan1} {on <DEVICE-NAME>}

Parameters

show interface {<INTERFACE-NAME>|brief|counters|ge <1-4>|me1|port-channel <1-2>|

The following command shows the state of Energy-efficient Ethernet, where:
  • Enable: Indicates if Energy-Efficient Ethernet is enabled or disabled on the selected physical port. A value of '1' indicates enabled and '0' indicates disabled.
  • Active: Indictaes if Energy-Efficient Ethernet is active or inactive on the selected physical port. A value of '1' indicates EEE is active and '0' indicates inactive. Note, will be active only if the devices on both ends of the phhysical link support EEE.
