TCAM Space Configuration
RUCKUS devices store routing information for IPv4 and IPv6 routing in the same ternary content-addressable
memory (TCAM) table.
RUCKUS devices vary in the amount of TCAM space that can be allocated for IPv4 and IPv6 routing. Each IPv6 route entry uses more storage space then IPv4 route entries. The default, maximum, and minimum allocation values for each type of data are shown in the following tables.
Note: If you disable IPv6 routing, the TCAM space allocations do not change. If you want
to allocate the maximum possible space for IPv4 routing information, you must configure
the TCAM space manually.
Note: For the ICX 7550 and the ICX 7850,
values are used from the forwarding profile and there is no option to change these
values. When a new profile is selected, the values from the new profile are applied.
Refer to the
forwarding-profile command in the RUCKUS FastIron Command
Reference and the "Configuration Fundamentals" chapter in the RUCKUS
FastIron Management Configuration Guide for more information. TCAM Space Allocation on ICX 7650 Devices
