CAM IPv4flow Commands
IPv4Flow sub-partitions are supported on the E-Series TeraScale platform e
t
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 TeraScale.
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
cam ipv4flow (EXEC Privilege)
e
t
Configure the amount of CAM space in IPv4flow sub-regions.
This command is deprecated as of FTOS 8.3.1.0.

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
