I have installed WIC-2T card into 3620 (64MB DRAM) router. When i run "show ip interface brief" or "Show run" command, there is no serial interface available. But when I run "show diag" command on cisco IOS it is showing the WIC-Card information. I m using IOS version 12.3. can anybody help me to solve this problem ?
WIC-2t is not supported on NM-1E2W. You need an NM-1FE2W to support wic-2T. Or you can use WIC-1T instead on you NM-1E2W module.
