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.
Version 8.3.19.0 Introduced on S4820T
Version 8.3.10.0 Introduced on S4810
Version 8.4.1.0 Added support for l2-switched-pbr microcode.
Version 8.2.1.0 Added support for the ipv4-64k-ipv6 profile.
