Just a question about frame-relay and cisco routers: I was unable to get an
answer up to now, so I hope that someone here had the same problem before
and solved it.
All works correctly, but I can see once a week errors like the following
using "sh log":
*Mar 9 18:35:46: %FR-5-DLCICHANGE: Interface Serial0 - DLCI 134 state
changed to INACTIVE
*Mar 9 18:35:46: %LINEPROTO-5-UPDOWN: Line protocol on Interface
Serial0.2, changed state to down
*Mar 9 18:39:50: %FR-5-DLCICHANGE: Interface Serial0 - DLCI 134 state
changed to ACTIVE
*Mar 9 18:39:50: %LINEPROTO-5-UPDOWN: Line protocol on Interface
Serial0.2, changed state to up
This happens on a Cisco 2501 router, using encapsulation frame-relay. The
bandwidth (256k) is NOT full when this problem occurs, and when it occurs,
the line is always down for 1-3 minutes only.
I can only see another apparently strange problem: the local lan is
connected to a 3com 10/100 hub, and even if each local machine has a 100
Mbit connection to the hub, and even if the lan has a trafic of about 5% of
its capacity, I can see a large number of collisions with the command "sh
int e0" on that router (about 3000/day).
