Subject: Re: Frame-relay BW statement question
Dave,
In your config for serial 0, you have service-module t1 timeslots 1-12
This tells the interface that it has half the channels activated, therefore
the bandwidth for that interface is shown as 768K, as reported by the show int
s0 output. It is not checking the clock rate, it is acting off of this
configuration command.
The default behavior of IOS is to assume that bandwidth for any sub-interface
is the same as the main interface, unless you modify that with the bandwidth
command. In s0.302 you have the bandwdith 384 command, which sets the
bandwidth for that interface.
I cannot replicate teh show output for s0.330 in my lab, bandwidth does not
show in the output of the show frame relay map output. Is it teh same as
reported by the show int s.330 command?

Subject: Re: Frame-relay BW statement question
This does not look right to me.
To my knowledge, there is nothing in IOS that connects clock rate to an IOS
displayed bandwidth statement.
Could you post the device configs and the unedited show command outputs?
On my routers I have a clock rate defined of 72000, however my show commands
display the following:

Group - I have a frame relay question..... on the following show frame

issue, but is this determined by the cir of the line, or, the clock

configured. TIA.
