Hi ,
I have CSM module on the cat 6500 switch and the issue is the content switch module is not balancing the request to the servers.
IT only sends to one server were as it should do the load balance and send it to all the servers packets by packets.
Kindly let me know what needs to be changed on CSM (Virtual server) to do the load balancing properly.
No issues with config as confirm by another engineer.Probes been configured properly it was workingg fine before but not now.
Please have a look.

Hi Neha,
Looks like you are hitting this bug:
CSCei26434.
Thanks

Hi Inayath,
Thanks. But why is that only couple of servers with parameters are been hit? If bug is the cause then all the servers with any port number should not have been hit?
Thanks in advance.
Regards,
Neha.

Did you try to remove some of the reals ( leave only 3 or 4 ) to see if this still happens?
