Hi, No HSRP, VRRP or GLBP on this box.
#sh mac-address-table aging-time Vlan Aging Time ---- ---------- Global 300 no vlan age other than global age configured Routed MAC aging time: 300 seconds This is on our core, though so there are no hosts connected here. -Drew -----Original Message----- From: Matthew Huff [mailto:[email protected]] Sent: Tuesday, November 24, 2009 1:41 PM To: Drew Weaver; 'Lee' Cc: Cisco-nsp Subject: RE: [c-nsp] 6500 - What determines whether certain traffic is punted or not? Are you using first-hop redundancy like hsrp, glbp, vrrp? This can cause asymmetrical MAC based FIB timeouts which leads to unicast flooding. I didn't think these were RP switched, but it could be. If so, what is your setting for "mac-address-table aging-time" ? We have ours set > fib timeout...so: mac-address-table aging-time 14400 ---- Matthew Huff | One Manhattanville Rd OTA Management LLC | Purchase, NY 10577 http://www.ox.com | Phone: 914-460-4039 aim: matthewbhuff | Fax: 914-460-4139 -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Drew Weaver Sent: Tuesday, November 24, 2009 1:21 PM To: 'Lee' Cc: Cisco-nsp Subject: Re: [c-nsp] 6500 - What determines whether certain traffic is punted or not? Hi Lee, I believe you're referring to show 'platform hardware capacity' and nothing looks extremely out of the ordinary. -Drew From: Lee [mailto:[email protected]] Sent: Tuesday, November 24, 2009 1:14 PM To: Drew Weaver Cc: Cisco-nsp Subject: Re: [c-nsp] 6500 - What determines whether certain traffic is punted or not?

Well.. it was worth a shot :) Have you seen any syslog messages about a fib or tcam table overflow? Someone else will have to chime in with the show commands to see hardware resource utilization - I'm not at work & don't remember what they are. Sorry..
