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

Error Message
%DEC21140-5-COLL: [chars] excessive collisions
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
Ethernet segment that is full to capacity or by other equipment on the

or hub).
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 problem. If you
have mis-configured speed/duplex or auto-negoation
mismatchs then you could see collision

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.

Well a good thing to do is to segment your network. As you are working with
hubs, you'll get a big collision domain. It is more expensive but exchanging
the hubs with 3500 switches is a good idea. This way you can make seperate
VLAN's.
With these VLAN's you'll get smaller collision domains.

What are the stats? "Excessive" is highly relative. You may be seeing a
lot of collisions, but that would be expected if you have a lot of traffic
through that port. If there is no setting in the 4500 for speed or duplex,
then it is running 10 Mbps/half duplex. In half duplex world, collisions
Thank you. I verified that the module that I have is only half duplex /
10BaseT and the collisions are not as excessive as I first thought.

If you have the old NP-2E, your ports are 10mbps half duplex. If you have
the newer NP-2E-FDX, you have the option to set port duplex on the RJ-45
ports (not the AUIs) with the commands HALF-DUPLEX or FULL-DUPLEX at the
config-if prompt.
You can't set speed on a 10mbps module. The NP-1FE does su
half duplex. Configure
your switches accordingly.

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

Thats funny, I have a spare 3640 that I could use in place of the 4500. I
would need to purchase an Ethernet module though. On paper the 3640 and the
4500 seem very similiar performance wise, both have 100MHZ Risc processors
and have the same amount of memory. The 3640 can handle up to 128MB thoug
15 matches
