Folks
These messages appear on my router (Cisco 4700M) at a point of time
everyday. This is very strange because it happens between 2pm and 3pm
everyday. We tried replacing the patch cable, changing interface, etc.
%DEC21140-5-COLL: Unit 0, excessive collisions
%DEC21140-5-COLL: Unit 0
ving a lot of excessive collisions on
the Ethernet interface and therefore have decided to introduce CAT 5002
switch in to the LAN.
How best can we modify the LAN with the hubs and the switch to reduce
the collisions? Any opinion is welcome.
Regards,
Stanny.

I have a 4500 with a two port Ethernet module. Each port on the module
connects to a different 2924 switch and is in a different subnet. I keep
getting excessive collisions on the Ethernet interfaces, no runts, no
giants, no CRC errors, just collisions. Any thoughts? There is no command to
set
DEC21140 is a FastEthernet controller, Unit 0 means FastEthernet0 being in
slot 0 of your 4700M, Excessive collisions mean that a packet was dropped
after trying to get on the medium for 15 times. The cause of this could be a
full segment, or a faulty device. It also is important to know whether

Explanation A Fast Ethernet packet was dropped because too many attempts
to transmit it were stopped by collisions. This can be caused by a Fast

Hope that help.

If this is a fast ethernet interface, what are the
speed/duplex settings on the router port and the
device its connecting to? You shouldn't see collisions
at 100full unless theres a equipment pr
Three secondarys because we use VLSM in an OSPF environment of small
subnets.
The router has only a link with the internal WAN. It is the only
interface between the LAN and the rest of the corporate network.
Thanks for your suggestion.

nso that can
be bad for collisions for one. One way to solve this is to run an IGP so
that workstations can realize that the addreses are actually reachable
directly.

You may want to set your switch speed to 10Mbits an match up your duplex
too.
