Command Modes
CONFIGURATION
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.
microcode
microcode
Choose a microcode based on the CAM profile you chose. Not all microcodes are
available to be paired with a CAM profile.
• Enter the keyword default
to select the microcode that distributes CAM
space for a typical deployment.
• Enter the keyword lag-hash-align
to select the microcode for
applications that require the same hashing for bi-directional traffic.
• Enter the keyword lag-hash-mpls to select the microcode for hashing
based on MPLS labels (up to five labels deep).
• Enter the keyword ipv6-extacl
to select the microcode for IPv6.
• Enter the keyword acl-group
to select the microcode for applications that
need 16k egress IPv4 ACLs.
• Enter the keyword ipv4-vrf
to select the microcode for IPv4 VRF
applications.
• Enter the keyword ipv4-v6-vrf
to select the microcode for IPv4 and IPv6
VRF applications.
• E-Series TeraScale only: Select l2-switched-pbr microcode if you apply a
PBR redirect list to a VLAN interface and want to prevent Layer 2 traffic
from being redirected and dropped.
l2-switched-pbr (IPv4-LDA)
microcode allows only Layer 3 traffic to be redirected while Layer 2 traffic is
switched within the VLAN.
