I have 2 Cat6509s w/NAM 1.2 at the CORE of my switched LAN. Should I be able to use the ART mib in 1.2 to my advantage without any other probes. Can it be used with NAI sniffer or Real-Time Monitor 1.3 in any way. Currently we have no solution to measure ART. I would love to use the ART mib with out having to any additional probes.
