Hi all,
I am having trouble directing a SPAN session through both a 2940 and 2960G switch. I have a Nexus 5K provding/outputting a SPAN session, going to to an interface on the 29xx configured as a SPAN source. I then have another interface on the 29xx configured as a SPAN destination, however no interesting traffic is egressing that interface.
More details - the 5K is sending the traffic unencapsulated (confirmd by packet capture) at about 10000 packets/sec. (~30Mb/sec) The 29xx is reporting the same traffic ingressing it's SPAN source interface (configured for both tx and rx traffic). The SPAN destination interface (no ingress traffic permitted) is reporting almost no outpout traffic (confirmed by packet capture). It seems the packets are getting "lost" in the switch between the source and destination SPAN interfaces.
When I very first apply the SPAN config, the detination interface reports approx 600 pps output, but this then goes to nearly 0 in a couple of minutes!
There are no clues in the logs, and the cpu is very low....
Any ideas greatly appreciated, please let me know if you need further info.
Cheers,
Jeremy
