Losing packets in a Port Channel

Unanswered Question
Jan 22nd, 2009

Port channel set up between a 6509 and a 3750. I am consistently losing HTTP keepalive packets going from my CSS tot he server. However, ICMP packets make it every time.

It appears the HTTP packets hit the port channel on the 6509, but never make it to the 3750. All other traffic seems to be normal.

I have this problem too.

Hi tmcmurray,

I've seen this, but the protocol involved was Oracle TNS. Frequently, the communication between the client and the db server stopped, but all other traffics were ok.

The problem was related with the etherchannel load balance mechanism. It seemed to stop working.

After being blamed a couple of days, I discovery the issue and a reboot solved it.
