Spanning port on 6509.

The command span 8/15 (Router with DS3) 9/10 (sniffer) shows no traffic. All I see are HSRP broadcast. The sniffer works fine we spanning a port on another switch. No matter what ports I span on the 6509 I only get HSRP broadcase.

Re: Spanning port on 6509.

Can you give the exact configuration you are using, code rev, and interface statistics (in/out frame counts for uni/multi/broadcast) for the src and dst span ports? Most importantly are the frame counts incrementing (tx and/or rx) on both ports?

Try to configure your destination port to be on the same vlan as your source port before issuing the span command.
