on ethernet interfaces anymore.
I was at a branch office where the users could not access the corporate

the FastEthernet as the Serial subinterfac
An interesting read, particularly since I am reviewing Kennedy clark's cisco
Lan Switching book prior to reviewing Cat5K and Cat 3920 configuration.
I am somewhat surprised at both the phenomenon and the concludion. Spanning
