Hello,
i'm trying to understand some problems on the ethernet of router cisco3640,i find a lot of collisions and deferred.My topology is :
Ethernet---router A ----FM-----router B----Ethernet
(10Mb/s) (10Mb/s)
and these are logs in 6 hours about :
sh int eth:
0 output errors, 24042 collisions, 0 interface resets
0 babbles, 0 late collision, 6215 deferred
-----------------------------------------------------
sh contr eth:
rx ring entries=32, tx ring entries=64
rxring=0x3123B80, rxr shadow=0x60F3D534, rx_head=24, rx_tail=0
txring=0x3123DC0, txr shadow=0x60F3D5E0, tx_head=30, tx_tail=30, tx_count=0

tx_exc_collision_err=0, tx_buff_err=0, fatal_tx_err=0
hsrp_conf=0, need_af_check=0
-----------------------------------------------------
In the ethernet is open the bridge, and i had applied the following access-liston the ethernet :
bridge-group 1 input-lsap-list 200
bridge-group 1 input-type-list 201
access-list 200 permit 0x0000 0x0505
access-list 201 deny 0x0000 0xFFFF
and i didn't find these errors.
CAn anyone help me?
It's a real problem or it isn't seriously problem?
My topology and all hosts talk to 100Mbit/sec and i'd like to upgrade the ethernet in fastethernet.
Thanks for your collaborations.
Regards
Roberto Paoletti
