Usage
Information
When this command is enabled, if a Policy Map containing classification rules (ACL and/or
dscp/ip-precedence rules) is applied to more than one physical interface on the same port
pipe, only a single copy of the policy will be written (only 1 FP entry will be used).
Note that an ACL itself may still require more that a single FP entry, regardless of the number
of interfaces. Refer to IP Access Control Lists, Prefix Lists, and Route-map in the FTOS
Configuration Guide for complete discussion.

profile
Choose one of the following CAM profiles:
• Enter the keyword default to specify the default CAM profile.
• Enter the keyword eg-default to specify the default CAM profile for
EG (dual-CAM) line cards.
• Enter the keyword ipv4-320k to specify the CAM profile that provides
320K entries for the IPv4 Forwarding Information Base (FIB).
• Enter the keyword ipv4-egacl-16k to specify the CAM profile that
provides 16K entries for egress ACLs.
• Enter the keyword ipv6-extacl to specify the CAM
profile that provides IPv6 functionality.
• Enter the keyword
l2-ipv4-inacl to specify the CAM
profile that provides 32K entries for ingress ACLs.
• Enter the keyword unified-default to specify the CAM profile that
maintains the CAM allocations for the IPv6 and IPv4 FIB while
allocating more CAM space for the Ingress and Egress Layer 2 ACL,
and IPv4 ACL regions.
• Enter the keyword ipv4-vrf to specify the CAM profile that maintains
the CAM allocations for the IPv4 FIB while allocating CAM space
for VRF.
• Enter the keyword ipv4-v6-vrf to specify the CAM profile that
maintains the CAM allocations for the IPv4 and IPv6FIB while
allocating CAM space for VRF.
• Enter the keyword ipv4-64k-ipv6 to specify the CAM profile that
provides an alternate to ipv6-extacl that redistributes CAM space
from the IPv4FIB to IPv4Flow and IPv6FIB.
