it is not a good idea to connect a destination span port to another switch.

See URL: http://www.cisco.com/warp/customer/473/41.html#topic8-2

for an example of the consequences of doing that.

Since you have a cat5000 it is not possible configure remote SPAN. Remote SPAN is really the solution you are looking for.

More details on it is found at

For now you'll have to just setup 2 sniffers on each switch until you get to upgrade the cat5000 to a cat6k or catalyst 4500.

Hi,

I'm a little confused (no 5000s in my network).

What does "RSPAN source is not supported in Catalyst 5000 family switches. RSPAN destination is shared with local egress sessions." mean?

See http://www.cisco.com/univercd/cc/td/doc/product/lan/cat6000/sw_5_4/config/span.htm#xtocid10.
