Need to span more than 2 ports on a 6500

Unanswered Question

We already have a system that is using a SPAN port, and we're about to implement an IDS with 3 sniffing interfaces. Unfortunately, all network devices are plugged into our two 6500's that are running as VSS, and we need a total of 4 SPAN ports. I'd prefer to not add any additional switches, but I'm at a loss for any other ideas. Anyone have thoughts on this?


Thank you.

Hi Allyn,


If you want to configure 2 span ports then you can create 2 session in 6500 as there is a limit for 2 session only for local span configuration in 6500,check out the below link for more information and guidelines on span port configuration in 6500.

Hope to Help

If you can't buy new switches, can you buy taps? Much cheaper than switches.
