It is an aggregation switch that feeds back via L3. Agreed - we had PSIRT look into it and the "solution" is probably going to be removing ip verify from the CLI parser :-( We had another 3550 replace a struggling 2621 and it blew it away.The ACL capability on the 3550 seems a lot more capable but the lack of unicast RPF is irritating. (More irritating, 'ip verify unicast reachable-via...' is accepted but silently does nothing) I'd be very interested to hear what conditions you've found causeIn a new building deployment we used 4500 Sup-IVs as MDF/IDF anchors and populated the distributions with 3550-48s. Most of the 4500s had one 48 port copper 10/100/1000 blade to supply gig-to-desktop where needed (their ASICs are overloaded 8-to-1 so be careful about placement). The 4500 not only doesn't do uRPF, it doesn't do flow either. The ACLs/MLS features are nice, supporting input ALCs, 'established' keyword, and logging (unlike, say MLS to a 5500 NFFC). It will not process switch these packets but rather "forks" a copy to the CPU to log if necessary. It is very annoying that neither 3550 nor 4500 support uRPF. Does anyone know if the 3750 does? Jeff
