Cam Profiles - Dell Force10 S4810P Configuration Manual

• Either ExaScale 10G or 40G CAM line cards can be used in a system.

CAM Profiles

Dell Force10 systems partition each CAM module so that it can store the different types of information.
The size of each partition is specified in the CAM profile. A CAM profile is stored on every card,
including each RPM. The same profile must be on every line card and RPM in the chassis.
There is a default CAM profile and several other CAM profiles available so that you can partition the
CAM according to your performance requirements. For example, the default profile has 1K Layer 2
ingress ACL entries. If you need more memory for Layer 2 ingress ACLs, select the profile

space according to the way Dell Force10 systems are most commonly used. In general, non-default profiles
allocate more space to particular regions to accommodate specific applications. The size of CAM
partitions is measured in entries. The total CAM space is finite, therefore adding entries to one region
necessarily decreases the number available to other regions.
Note: Not all CAM profiles and microcodes are available for all systems. Refer to the Command Line
Interface Reference Guide for details regarding available profiles for each system.

Description
An all-purpose profile that allocates CAM space according to the way Dell Force10 systems are most
commonly used.
Available Microcodes: default, lag-hash-align, lag-hash-mpls
For EG-series line cards only. EG series line cards have two CAM modules per Port-pipe.
Available Microcodes: default, ipv6-extacl
Provides 320K entries for the IPv4 Forwarding Information Base (FIB) and reduces the IPv4 Flow
partition to 12K.
Available Microcodes: default, lag-hash-mpls
Provides 16K entries for egress ACLs
Available Microcodes: acl-group
Provides IPv6 functionality.
Available Microcodes: ipv6-extacl
Provides 32K entries for Layer 2 ingress ACLs and 28K entries for Layer 3 IPv4 ingress ACLs.
Available Microcodes: default
Maintains the CAM allocations for the and IPv4 FIB while allocating more CAM space for the Ingress
and Egress Layer 2 ACL, and IPv4 ACL regions.
Available Microcodes: ipv6-extacl
l2-ipv4-inacl.
