>From memory, that MIB doesn't appear on 3550 and 3750 switches. It does appear on 6500s, even in VRF lite, but I believe you have to have an RD set on one or more VRFs (or maybe it was a later software upgrade that made it appear) In any event, the MPLS-VPN MIB is EXTREMELY SLOW to poll, due in large part to is EXCEPTIONALLY POOR DESIGN. _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
