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 ICX 7550, ICX 7850, ICX 8100, and ICX 8200
devices, 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
| Default | Maximum | Minimum | |
|---|---|---|---|
| IPv4 route entries | 98304 | 131072 | 98304 |
| IPv6 route entries | 5120 | 7168 | 5120 |
