WAAS, and 4948 switches with wccp

[cstockwe]

Hi,

I know the 4948 switches do not support a redirect list as per the WAAS deployment cookbook I found somewhere else on netpro.

The problem I get is that I cannot telnet to the loopback interface of the 4948 when I've got wccp and waas functioning at the wan edge layer. It pings ok; but it seems that the telnet packets are being redirected to the WAEs and not 'coming back' - the session hangs.

I can telnet to other IPs bound to interfaces on the 4948, and the WAAS appliance vlan interface address - its just the loopback that hangs.

I have "ip wccp 61 redirect in" on the WAN interface of the 4948 and " ip wccp 62 redirect in" on the LAN interface and the WAAS appliances are using L2 redirect and masking.

Note that I've also got the the 61 and 62 'reversed' at the DC end compared to the branch as per WAAS cookbook/text book.

On the 3750's we could set up a redirect list and deny the loopback from being redirected- but how can I get around this on the 4948?

I can get around it by creating a "loopback" vlan and assign the address to that, but I'd prefer just to have the standard loopback interface by itself working.

Any ideas?

Also, what IOS is recommended for the 4948 in this wccp/waas scenario?

Thanks

Hello cstockwe,

I have the same problem as you. I have two CAT4948 SWs, one with WCCP config (SW1) can be telneted via loopback interface, but the other (SW2) can't. The two SWs have the same IOS version (cat4500-entservicesk9-mz.122-46.SG), the same model, the same size of flash&RAM memory, the same config...

And all the interfaces except the loopback interface on the SW2 can be telneted.

You mentioned you have workaround solution, how to do the solution ? Can you explain the detail ?

Thanks!

Just make sure you have an active Layer 3 link between the switches.

See Dan's reply in this thread above.
