`profile`

Syntax

profile {l3-agg | l3-core}

Description

Sets the hardware forwarding table profile on an 8320 switch. The default mode, l3-core, is optimized for layer 3 forwarding with more table space allocated to route entries. For networks with many hosts and fewer routes, a layer 2 oriented mode, L3-agg, is available that allocates more table space to host entries.

On an 8325 switch, the hardware forwarding table profile is set to L3-agg and cannot be changed.

NOTE:

The switch must be rebooted for a mode change to take effect.

NOTE:

Prior to release 10.2, the forwarding table mode was configured with the command platform forwarding-table-mode {3 | 4}. When upgrading to release 10.02, any existing configuration is converted as follows: table mode 3 is converted to l3-agg and table mode 4 is converted to l3-core.
