I have 2 Switches A& B connected to each other over Portchannel interfaces each with 2 physical interface in it.My query is related to physical errors that occur on one of these physical interfaces.
A is connected to B via PoCh with interfaces gig 2/3 & 2/4.B is similarly connected to A via gig 2/3 & 2/4.
1)Now it appears gig 2/4 on both A & B are bouncing for couple of days.Also i can see large amount of runts,giants,frames,input errors & CRC on these two interfaces & correspondingly the PoCh shows CRC as well, which should be the accumulated aggregrate of individual ports.
There are some performance issues on this link.However when extended ping is used to test the connectivity from A thru B to reach a certain destination which lies beyond B,the response is gud with no drops.
I was wondering..wont the icmp response indicate anything problematic if the errors are there on the interfaces? Or is that this would only come into picture when there is huge utilisation on the link.When checked the usage was around 10%.
2.Also, any idea what does lost carrier on an interface indicate..although this is not related to this specific case!
Any comments/suggestion on this would be highly helpful.
Thanks in advance!!
