Re: trucking, Vlans,

I'm configuring a Cat 4006 and a 2600 router. I enable a trunk on the 4006. And on the router I made a sub interface.

since the I get a packet lose or at lease it looks like it. The connection is very slow. Did a ping test and it looks like I lose 1/3 or 1/2 of my packets.

Config from the router will help as well. Also, do not base slow performance on results of pinging the 4006's management IP address(sc0). ICMP is a low priority for CAT4000 and response is slow. Try pinging some devices on the 4006 instead.

Did you hardcode the router interface to 100/full seeing that the switch side is hardcoded ?

denis.roy · ‎12-15-2004

yes, both are using Full dup. and 100.

selvaraj_s · ‎12-15-2004

Hi,

This is an cable or the Port settings issue. Check the Trunk cable (Try to change the cable) and also chk trunk port (Both side) for 100/full.

majorward · ‎12-16-2004

Selvaraj,

The troubleshooting method you need to deploy to rectify this issue is as following: From my knowledge, the 2601? router maximum ethernet intergrated FIB speed is 10Mps Half-Duplex.

A) Verify physical layer function on the router by typing the command in the user prompt:

router2601#show interface etherntet 0/0

(Pay attention to incremental CRC and FCS errors.

To enable IEEE 802.1Q trunk frames forwarded into the FIB to the outgoing interface of the relay, the following command strcuture must be deployed.
