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
EgL2ACL : 2K entries
EgIpv4ACL : 4K entries
Mpls : 60K entries
IPv6FIB : 12K entries
IPv6ACL : 6K entries
IPv6Flow : 6K entries
Mcast Fib/Acl : 3K entries
Pbr : 0K entries
