Cisco Interfaces In Use

Jan 2024

Introduction

A really useful task to perform when looking at remote systems is to see what interfaces on a Cisco Switch are in use (as in connected). Lets look at how to see what interfaces we are using:

sh interfaces status
Port Name Status Vlan Duplex Speed Type
Gi0/1 connected 2 a-full a-1000 10/100/1000BaseTX
Gi0/2 notconnect 2 auto auto 10/100/1000BaseTX
Gi0/3 notconnect 2 auto auto 10/100/1000BaseTX

Gi0/41 notconnect 3 auto auto 10/100/1000BaseTX
Gi0/42 notconnect 3 auto auto 10/100/1000BaseTX
Gi0/43 notconnect 3 auto auto 10/100/1000BaseTX
Gi0/44 notconnect 3 auto auto 10/100/1000BaseTX
Gi0/45 connected 1 a-full a-1000 10/100/1000BaseTX
Gi0/46 connected 1 a-full a-1000 10/100/1000BaseTX
Gi0/47 notconnect 1 auto auto Not Present
Gi0/48 notconnect 1 auto auto Not Present

In the above example
