The 4948E may be a good fit but the full enterprise image is pricy. It has better QOS and 1G/10G SPF+ uplinks.

Other than a /128 ACL requiring ff:fe in the right spot (someone detailed why either here or NANOG when I complained about it previously) to store it in TCAM, I don't have any major complaints with their IPv6 support. I'm not doing anything fancy, just pushing packets with anti-spoofing ACLs. I don't do any policing with them though, and that's really where you will probably be annoyed the most. ~Seth _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
