[nsp] 6500/7600 with large ARP/MAC tables?

[Alex Rubenstein]

Hello,

I personally run a Hybrid 6509/s2/msfc2/pfc2 with about 15,000 arp
entries, and about 325 interfaces. It runs well. It's got 12.1.19E1.

It moves just around a gigabit/sec. It's got about 4,000 routes.

CPU utilization for five seconds: 9%/2%; one minute: 12%; five minutes: 12%




I have a customer who has only two interfaces, but is over the 20k range
in mac entries.
