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.
