CAM IPv4flow Commands
IPv4Flow sub-partitions are supported on 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
