Has anyone encountered problems with setting a dual capture with an agent residing on a Cisco 3550 switch?  It appears that the IOS 12.1(11)EA1 will not allow both Tx and Rx packets on a destination "monitor session", so that the agent can't communicate with the server.  I know a tap will solve this problem, but I'd like Cisco to admit it's a problem, not a feature.

I am finding that more and more switches are not allowing "in packets" on the destination port when spanning.  A friend recently found that with the latest version of IOS on the 6509, in packets are no longer allowed.

One workaround for this problem is to have two NICs installed in the computer used to capture the packets.  One NIC is used for packet capture, and the other is for communications with the agent.

When you select the agent, it will give you the option to select with NIC you want to use for doing the capture.  It would be at that point you would select the NIC connected to the span port.
