Checking Interfaces Status
This example shows how to check module status for all modules on your switch:
Switch# show module all

Checking Interfaces Status
You can view summary or detailed information on the switch ports using the show interfaces status
command. To see summary information on all ports on the switch, enter the
show interfaces status command with no arguments. Specify a particular module number to see
information on the ports on that module only. Enter both the module number and the p ort number to see
detailed information about the specified port.
To apply configuration commands to a particular port, you must specify the appropri ate logical module.
For more information, see the “Checking Module Status” section on page 5-1.
This example shows how to display the status of all interfaces on a Catalyst 4500 series switch, including
transceivers. Output of this command displays “Unapproved GBIC” for non-Cisco transceivers:
Switch#show interfaces status
Port Name Status Vlan Duplex Speed Type
Gi1/1 notconnect 1 auto auto No Gbic
Gi1/2 notconnect 1 auto auto No Gbic
Gi5/1 notconnect 1 auto auto 10/100/1000-TX
Gi5/2 notconnect 1 auto auto 10/100/1000-TX
Gi5/3 notconnect 1 auto auto 10/100/1000-TX
Gi5/4 notconnect 1 auto auto 10/100/1000-TX
Fa6/1 connected 1 a-full a-100 10/100BaseTX
Fa6/2 connected 2 a-full a-100 10/100BaseTX
Fa6/3 notconnect 1 auto auto 10/100BaseTX
Fa6/4 notconnect 1 auto auto 10/100BaseTX

This example shows how to display the status of interfaces in error-disabled sta te:
Switch# show interfaces status err-disabled
