Routing Resources

If IPv6 routing is enabled on the device, the following table describes the number
of TCAM entries used by the various features:
The Router Resources page enables you to adjust the TCAM allocation.
If you change the TCAM allocation incorrectly, an error message is displayed. If
your TCAM allocation is feasible, a message is displayed that an automatic reboot
will be performed with the new settings. Router resources can be modified
incorrectly, in one of the following ways:
• The number of TCAM entries you allocate is less than the number currently
in use.
• The number of TCAM entries that you allocate is greater than the maximum
available for that category (maximum values are displayed on the page).
To view and modify router resources:
STEP 1 Click Administration > Router Resources.
The following fields are displayed for IPv4 routing:
• Neighbors—Count is the number of neighbors recorded on the device and
TCAM Entries is the number of TCAM entries being used for the neighbors.
• Interfaces—Count is the number of IP addresses on interfaces on the
device and TCAM Entries is the number of TCAM entries being used for the
IP addresses.
• Routes—Count is the number of routes recorded on the device and TCAM
Entries is the number of TCAM entries being used for the routes.
