[c-nsp] Best practice for CAM and ARP aging timers

2011-06-02 Thread george
I'm trying to establish consensus on best practice CAM and ARP aging timers for Cat6500 12.2(33)SXI5. Various cisco docs state these should be synched to minimise unknown unicast flooding. I'm looking into modifying them from the default values (ARP timer 14400 sec, MAC aging time 300 sec) to mi
