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 bidirectional 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.
