CAM IPv4flow Commands

IPv4Flow sub-partitions are supported on the E-Series TeraScale platform e

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 IPv4Flow region is

further sub-divided into 5 regions: System Flow, QoS, PBR, Trace-lists, Multicast

FIB & ACL.

You can change the amount of CAM space allocated to each sub-region. You can

configure the IPv4Flow region in both EtherScale and TeraScale. In EtherScale, these

commands allocate CAM space for IPv4Flow sub-regions and the IPv4 ACL region.

Like CAM profiles, you can configure the IPv4Flow region from EXEC Privilege

and CONFIGURATION mode.

The CAM IPv4flow commands are:

• cam ipv4flow (EXEC Privilege)

• cam-ipv4flow (CONFIGURATION)

• show cam-ipv4flow

Term Explanation

Stack-Unit Lists the stack unit or units that are checked. Entering

all

shows the status for all stacks.

Portpipe Lists the portpipe (port-set) or port pipes (port-sets) that are

checked. Entering all shows the status for linecards and

port-pipes in the chassis.

CAM Partition Shows the CAM profile of the CAM

Available CAM Identifies the amount of CAM space remaining for that profile

Estimated CAM per Port Estimates the amount of CAM space the listed policy will

require.

Status Indicates whether or not the policy will be allowed in the

CAM
