If IPv6 routing is enabled on the device, the following table describes the number
of TCAM entries used by the various features:
The Routing 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. Routing 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 routing resources:
STEP 1 Click Administration > Routing Resources.
The following fields are displayed for IPv4 Routing Resources:
• Neighbors(1 TCAM entry per neighbor)—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(2 TCAM entries per interface)—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 (1 TCAM entry per route)—Count is the number of routes recorded
on the device and TCAM Entries is the number of TCAM entries being used
for the routes.
• Total—Displays the number of TCAM entries which are currently being
used.
