Show interface vs show ip interface

[gsplsngr]

I am getting ready to take the CCNA test but need to have these commands clarified

show interface
show ip interface

whill show interface give you the same results as show ip interfaces and visa versa and how are they used differently?

Take a look at the output below. The diff is obvious. Basically the "sh ip int" allows you to see the status of all the protocols for that interface. Whereas the "sh int" shows you more of the physical attributes of the interface.

gsplsngr,

Best way to learn this is just what Jsteve did - look at the output!!

CCNA test is full of sample outputs with questions about them.

Best way to prep for the exam is to get on a router or a sim and go through as many commands as possible and look at the output so you know what it does as well as what it looks like!

Several people in my area have taken the CCNA over the last 3 weeks - lots of "show" commands, lots of switching!

I hope this helps!
