We have a Websense server connected to a Catalyst 2970, and also a PIX 515 through which outbound http traffice passes for users to surf the web.
The problem is, when I enter the "monitor session 1 destination" command on the interface the Websense server is connected to, we can no longer reach the server.
We had this working on a 2950, but it would occasionally lock up, so we are trying a 2970.
One difference I noticed in the output of "show monitor session 1 detail" is that the Ingress Encapsulation is NATIVE on the 2950, and it shows UNTAGGED on the 2970.
Not sure if that is relevant, and I see now way to manually set that to NATIVE.
