Excessive collision in the Router - Page 2

UCBNOCWAN · ‎10-10-2008

Hi All in Router i am the getting error:AMDP2_FE-6-EXCESSCOLL: Ethernet0/0 TDR=1, TRC=0

Router is connected to Switch, both router and switch config is below

can some body tell me how to fix up this issue as i am planning to change Duplex setting router from half duplex to full duplex

will this solve my problem

Router config:-

interface Ethernet0/0

description ### LAN ###

ip address 10.21.1.2 255.255.0.0

ip access-group 141 in

ip route-cache flow

half-duplex

standby ip 10.21.1.1

standby preempt

end

====================

Switch config

interface GigabitEthernet0/1

description ***FREE***

no logging event link-status

no snmp trap link-status

no mdix auto

spanning-tree portfast

spanning-tree bpdufilter enable

spanning-tree guard root

Hi,

%AMDP2_FE-6-EXCESSCOLL: Ethernet0/1 TDR=0, TRC=0

I am also facing same issue but my frame size is 256 only , but i am not hitting reaming frame sizes like (128,512,1024 Frame Sizes).

Do both sides of the link duplex match?

Hi Joseph,
Yes both sides are FULL DEPLEX only.
But it is hitting only 256 Frame size in C5921 IOS .
Can I know what is the use of these commands:
1. logging discriminator EXCESS severity drops 6 msg-body drops EXCESSCOLL
2. logging console discriminator EXCESS

I don't see how your getting any collisions if both interfaces are (truly running) full duplex.

Since I see you're a Cisco Employee, you don't have access to TAC or any other internal resources to address this?

logging discriminator EXCESS severity drops 6 msg-body drops EXCESSCOLL
logging buffered 50000
logging console discriminator EXCESS
