CAM Layer 2 ACL Commands
IPv4Flow sub-partitions are supported on the E-Series TeraScale platform e
t
The CAM Layer 2 ACL commands are:
• cam l2acl (EXEC Privilege)
• cam-l2acl (CONFIGURATION)
• show cam-l2acl
The 18-megabit user configurable CAM is divided into multiple regions such as Layer 2 FIB, Layer 3
FIB, IPv4Flow, IPv4 Ingress ACL, etc. The Layer 2 ACL region is further sub-divided into 6 regions:
Sysflow, L2ACL, PVST, QoS, L2PT, FRRP.
You can change the amount of CAM space, in percentage, allocated to each sub-region. The amount of
space that you can distribute to the sub-partitions is equal to the amount of CAM space that the selected
CAM profile allocates to the Layer 2 ACL partition. FTOS requires that you specify the amount of
CAM space for all sub-partitions and that the sum of all sub-partitions is 100%.
Like CAM profiles, you can configure the Layer 2 ACL partition from EXEC Privilege mode or
CONFIGURATION mode.
