WAAS cluster problem when WAAS reload

Hello,

I have a datacentre with a 2 * 6500 and a WAAS cluster. When the WAAS are reloaded in the datacentre, I have a lot of applications problem. We need to turn off wccp on the switches and turn on wccp again to have applications work again. Would anybody know why and provide a link to cisco website which could explain this issue?

Thanks

Hi,

it's difficult to point you to the right direction without knowing more details about the problem. I suggest to check the following:

- what are the applications impacted? (all the apps / specific ones)

- only some sources/destinations or all the traffic?

- are the apps slow or simply not working?

- does the problem happen when reloading both central WAE's or just one of them?

after you narrowed down the issue, you might want to look into a specific area to troubleshoot on. Here you have a good starting point:

http://docwiki.cisco.com/wiki/Cisco_WAAS_Troubleshooting_Guide_for_Release_4.1.3_and_Later

You might want to look into the "Troubleshooting WCCP" section of that document.

Depending on your findings you might also need to grab sys-reports from the WAE's involved and tcpdump on core/edge location.

hope this helps,

Fabrizio
