If a the standby RPM has a profile different from the primary RPM, the card reboots so that it can load
the proper profile.
To change the CAM profile on the entire system:
CAM Allocation
User Configurable CAM Allocations is available on platforms: c s
Allocate space for IPV4 ACLs and QoS regions, and IPv6 6 ACLs and QoS regions on the C-Series and
S-Series by using the
cam-acl command in CONFIGURATION mode.
The CAM space is allotted in FP blocks. The total space allocated must equal 13 FP blocks. Note that there
are 16 FP blocks, but the System Flow requires 3 blocks that cannot be reallocated. The default CAM
Allocation settings on a C-Series system are:
L3 ACL (ipv4acl): 6
L2 ACL(l2acl) : 5
IPv6 L3 ACL (ipv6acl): 0
L3 QoS (ipv4qos): 1
L2 QoS (l2qos): 1
L2PT (l2pt): 1
MAC ACLs (ipmacacl): 2
ECFMACL (ecfmacl): 0
VMAN QoS (vman-qos): 0
VMAN Dual QoS (vman-dual-qos): 0
The
ipv6acl and vman-dual-qos allocations must be entered as a factor of 2 (2, 4, 6, 8, 10). All other profile
allocations can use either even or odd numbered ranges.
