Hi All,
I have an issue with one of my switch ( 4500 series) .
Actual Scenario:
--------------------
We have a server which has two interfaces and each assigned with an IP address ( in the range[10.49.8.132/27]) . Eth0 IP:10.49.8.135 and Eth1 IP:10.49.8.136 . Eth0 is connected to Switch-A and Eth-1 is connected to Switch-B . When tried to ping Eth0 IP it is success from switch-A whereas Eth-1 is not a success. Now the same IP's are pingable from the other switch-B . I am not sure what might be wrong . Please advise .
Thanks,
Babjani.

Hi Mark Malone,
Thanks for your prompt response . But now the issue has been subsided and the errors are not there anymore. Few servers on the switches are not able to communicate with others . We have verfied everything on server side bonding to spanning tree as well . But no luck . If you need some more info please let me know I will share it with you .
Thanks,
Mohammad.

Hello Mark,
No..! it(Gig1/5) is not flapping , but occasionally. Gig1/5 is an uplink to the customer/client site and it is a router. Here I have attached the logs of the switches.
Thanks ,
Mohammad.
