Supernet CAM partition sharing
As of 3.2.00 code and later, TCAM sharing within a particular CAM Section is now supported.
For example: In Multi-Service IronWare software prior to version 03.2.00, the TCAM resources
could not be shared between the 32 levels of the IP Forwarding Information Base (FIB). Beginning
with version 03.2.00, TCAM allocation is optimized to allow dynamic allocation of resources to each
level within a particular resource pool. If one level runs out of TCAM resources, it can use resources
that have been allocated to another level and remain unused. This feature is applicable to IPv4,
IPv6, and L-3 VPN routes.
NOTE
CAM Sharing is not shared across resource pools, such as IPv4, IPv6 or L-3 VPN. Only shared
between levels of each pool.
For example: IPv4 may not use CAM resources from the IPv6 resource pool.
Displaying CAM partition
The show cam-partition command provides information about available CAM in three formats: raw
size, user size, and reserved size.
