Three Cisco IOS Tips…

David Davis David Davis Profile: David Davis

I commonly get questions from junior admins about the Cisco IOS. Here are 3 tips that I came up with:

1. How do you find available options on a command? (get help)

Use the ?.

Example: Options on an interface command:
R1# show i?
R1#: show interfaces ?

2. How do you ping an address?

R1#: ping  (enter)

And how do you do an advanced ping?

Easy, just type “p” or “ping” and press enter. Then, answer the questions as they are asked.

3. How do you copy an IOS file from TFTP into Flash Memory?

R1# copy tftp flash  (enter)

(and fill out the questions as they are asked)
