I have a 2621 router with a WIC 2T card. Currently onr port is connected to provider's DSU mux. THe provider hands off 3MB link but when I do a "show int s0/0" it only shows 1.5MB. Do I have to combine both ports to get 3MB?
'show int s0/0' would show *configured* bandwidth on the interface which does not have to be a real bandwidth. That number is used by routing protocols and some QoS mechanisms to determine how fat is your pipe (how desirable is this path) but does not affect real bandwidth on interface.
How do I know I'm getting full 3MB from the provider? Does one port in that WIC support 3MB?
By default, one port in WIC-2T supports 2 Mbps max (synchronous), but in some slots, it can support up to 8Mbps:
With some hardware (sorry don't know about your's) the serial clockrate is shown by the show controllers command.
