if you're still on a platform with 40Mbit cams it's beginning look kinda
tight as an internet router. you've probably got less than a year to
figure out what to do about this.

an f10 ej linecard cam paritioning scheme for example looks something like.

CamSize         : 40-Meg
                : Current Settings
Profile Name    : default
Microcode Name  : Default
L2FIB           : 15K entries
  Learn         : 1K entries
L2ACL           : 5K entries
  System Flow   : 102 entries
  Qos           : 500 entries
  Frrp          : 102 entries
  L2pt          : 266 entries
  PPVlan        : 100 entries
IPv4FIB         : 512K entries
IPv4ACL         : 16K entries
IPv4Flow        : 24K entries
  Mcast Fib/Acl : 9K entries
  Pbr           : 1K entries
  Qos           : 10K entries
  System Flow   : 4K entries
