too many collisions on my FE interface running a BGP session

Greetings......

I am running a BGP session with a carrier network and have terminated its link on my FE 0/1 3660 router.

For my location whatever bandwidth i am having is thru this link .

I am seeing a lot of COLLISIONs on that interface.

the "counter for collision" rises to abt 1500 in abt a day`s time.

Is this normal or due to some prob with the media or something else.

Appreciation in advance to the replyer.....

Re: too many collisions on my FE interface running a BGP session

Since you're seeing collisions, you have the interface set to half-duplex. Are you seeing any late collisions? If so, you have a duplex mismatch, most likely.

Can you go to full duplex? That would eliminate the collisions you're seeing.

Re: too many collisions on my FE interface running a BGP session

Dear mickey.....

I had just posted a query for the collisions i had been getting on my FE.

first of all thanks a lot for being so quick to reply to and secondly u were rite that it was half duplex.

But the thing is i am changing it to Full-Duplex but it isnt changing.

After i give the command "Full-Duplex"......and see the interface...it still shows me "Half-Duplex"

Just take a look......should i decrease the DLY also

Re: too many collisions on my FE interface running a BGP session

according to your SH INT, you may be using a FE port, but it is seeing only 10/half. This would imply that your provider is only supplying a 10/half connection to you.

Expect collisions. 1500 per day is nothing. Figure that if collisions exceed 10% of your PPS, you have the *beginnings* of a problem with collisions.

Re: too many collisions on my FE interface running a BGP session

Thanks again......

Do u mean my Carrier provider is giving me 10/half.

As i am myself a provider...

Is it that the Full or Half duplex operations have to be enabled on both WAN ends .What i mean is , since my carrier has not config a full duplex operation , is it why i am not able to change it myself to Full-Duplex.
