Installing VWIC-1MFT-T1/E1 on 2821
by David Sudjiman ~ June 17th, 2009. Filed under: Cisco.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.
