There is a command we need to apply to switch the card module to E1 or T1 and this is the first thing you need to do before configuring the interface.
Router(config)#control? control-plane Router(config)#card type ? e1 E1 t1 T1 Router(config)#card type e1 ? <0-2> Card slot number (always 0 for 1800 series & 2801 routers) Router(config)#card type e1 0 1 Router(config)#control? control-plane controller Router(config)#controller E1 ? <0-0> Controller slot number Router(config)#controller E1 0/1/0 Router(config-controller)#
and it was REALLY hard to find this info if you using words like “configure vwic-1mft-t1/e1 2821″ and without knowing that you need to apply this command.
youre right it was hard to find, I had to figure it out in the command line and then do a search for card type t1 0 0 in cisco.com but your resource was the only one that said definitely DO this first. eh, thanks.
Such a straight forward info. I was very much confused as there was no controller in my SH run
Thanks mate.
