questions,\n\nAccording to cisco documentation, SPAN is supported in 6509 with 'no\nperformance impact'\n\nis this really true? I mean there has to be SOME performance hit\nthere? I am asking this because I am putting togethere specs for a\npossible snort machine that we need to snort off of a 6509 with 20\nvlans on it. and I plan to mirror several VLANs onto one physical\nfiber port that I can snort on.\n\ncurrent total usage is about 60Mbps. (all vlans included)\n\nthe other thing is that documentation says it only supports 2 set of\nSPAN? (no RSPAN) kind of limiting huh?
