show interfaces
show interfaces
Use the show interfaces privileged EXEC command to display the administrative and operational status
of all interfaces or a specified interface.
show interfaces [interface-id | vlan vlan-id] | [accounting | capabilities [module module-number]
| cpe [port port-id] | description | etherchannel | flowcontrol | media [interface-id] | pruning
| stats | status [err-disabled] | switchport | trunk | transceiver properties] [ | {begin | exclude
| include} expression]
Syntax Description interface-id (Optional) Valid interfaces include physical ports (including type, slot, and port
number) and port channels. The port-channel range is 1 to 6.
vlan vlan-id (Optional) VLAN ID. The range is 1 to
accounting (Optional) Display accounting information on the interface, including active
protocols and input and output packets and octets.
Note The display shows only packets processed in software; hardware-switched
packets do not appear.
capabilities
[module
module-number]
(Optional) Display the capabilities of the specified interface or all interfaces on the
switch. The module number is always 0. If you enter an interface ID, the module
keyword is not visible.
cpe [port port-id] (Optional) Display link status, speed, and duplex of all the customer premises
equipment (CPE) Ethernet ports. You must enter an interface ID to display this
keyword.
port port-id—Display only the designated CPE Ethernet port. The range is 1 to 4.
These keywords are available only on Long-Reach Ethernet (LRE) switches.
description (Optional) Display the administrative status and description set for an interface.
etherchannel (Optional) Display interface EtherChannel information.
flowcontrol (Optional) Display interface flowcontrol information.
media
[interface-id]
(Optional) Display the type of media connection. This keyword is available only
on LRE switches.
pruning (Optional) Display interface trunk VTP pruning information.
stats (Optional) Display input and output packets by switching path for the interface.
status
[err-disabled]
(Optional) Display the status of the interface, or display interfaces in
error-disabled state.
switchport (Optional) Display the administrative and operational status of a switching port.
trunk Display interface trunk information. If you do not specify an interface, information
for only active trunking ports appears.
transceiver
properties
(Optional) Display speed and duplex settings for an interface.
| begin (Optional) Display begins with the line that matches the expression.
| exclude (Optional) Display excludes lines that match the expression.
| include (Optional) Display includes lines that match the specified expression.
expression Expression in the output to use as a reference point.
