[mrtg] Re: Cisco line speed problem

[Meena Chockalingam]

Cisco routers get the line speed from the bandwidth statements. If you do 
not have any bandwidth statements included in the interface configuration 
then it is going to pick up a default speed of a T1(1.544Mbs) for serial 
interfaces. So use the bandwidth statement to set the speed correctly.

thanks,
Meena
