AFAIK 3500XL/2900XL do not support RSPAN functionality, so you won't be able to use this trick there. To: JOHN

Nice to have, if you like to know what your peers are doing ;) But seriously, the only real benefit is getting rid of mac-address learning and CAM table blowup. This kind of service applies perfectly to "port-to-port" services, where mac-address learning is unnecessary. to: dknov
