Re: excessive collisions
I have problem same as your when I config full-duplex on switch, then my router start give that kind of error. I think router don't support full-duplex (or i don't know how to config full-duplex on router). Check your setting (full/half duplex) on the interface that connected to (switch or hub).

Re: excessive collisions
Hope this hepls, 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.

Re: excessive collisions
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 you use a hub or a switch. However according to your statement that it only happens between 2 and 3 pm I assume that the cause is to be found in a heavily loaded segment. Check your load during this time and try to decrease it if so. It could also be worthwhile to check the status of your interface (output errors, deferreds etc.) Regards, Hans On CCO: DEC21140 Fast Ethernet controller error messages 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 LAN malfunctioning. Recommended Action No action is required.

Re: Excessive collisions
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 thought I think. What would be the advantage of replacing the 4500 with the 3640?

Re: Excessive collisions
Older models of the two port ethernet module for the 45xx series do not do full duplex. Newer models (last year or so) can do full duplex. (I think) No models do 100 meg, you need a FastEthernet module for that so you can't config speed. So I would wager that you have 2 ports of 10 meg half duplex. Configure your switches accordingly.

Re: Excessive collisions
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 support the SPEED command, but if you have a 2-port ethernet module it's definitely just 10mbps. -Gabriel McCall, CCDP/CCNP+Sec ""Lonnie Paschall"" <[EMAIL PROTECTED]> wrote in message 8pj5mq$fbn$[EMAIL PROTECTED]">news:8pj5mq$fbn$[EMAIL PROTECTED]... > I have a 4500 with a two port Ethernet module.

Excessive collisions
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 the duplex or speed on the module.

RE: Excessive Collisions
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. Every workstation gets a connection to the switch. This way every workstation has got an own collision domain. Wich means it isn't interfearing with other workstations. Maybe there are some other ways to do this, but this is my opinion on how to solve your problems.

This is because each packet must goto the router, and then back out the interface to the destination, which is all on the same collision domainso 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. > > The problem is that we've been having 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?

Three secondarys because we use VLSM in an OSPF environment of small subnets. The router has only a link with the internal WAN.
