I believe all you have to type is "clock rate" and if it is not correct you should receive an error

I thought the "show controllers" command required you put a space between the interface name and the number? (i.e. s 0/0 or serial 0/0 as opposed to s0/0 or serial0/0.)

That is right too. If you try to put the clock rate in a DTE, it won't let you.Cessation wrote:Dowima wrote:Hi everybody ?

Another, less convenient method is to look at the CTS, RTS, etc. values at the bottom of the show interface output on a serial link. I.e. bring one side up (no shut) and the other side down and check the values. Bring the other up and the first one down and check again. Not really a CCNA-level way of doing it but it should be imo.
