Use Show Interface Command

Show Interface is very useful command. This article is based on the below example.

1. To show one interface only, use show interface "interface" as example sh interfaces s0/0/1:0.

2. It should give you some hardware information. In our case Circuit # is DHZA045978 which your ISP may need it.

3. For troubleshooting, you my check any errors. In our case, you can see 7706 input errors.

4. Other useful information such as MTU, txload, reload, input rate and output rate.
