The 8320 Switch has two operation modes. The purpose is to provide the best match in terms of table sizes, depending on the role of the switch.
For example, if the 8320 is acting as an L2 Aggregator (deployed in the aggregation layer with L2 access) it will need large ARP/MAC tables, while when deployed as an L3 Aggregator or Core, it will need larger routing tables and very small ARP/MAC tables.
The mode that works best in the first case is called Mobile First Mode because it is the most common situation when the 8320 is aggregating L2 access switches and Aruba Mobility controllers.
The mode that fits the second case is called simply Routed Mode and it is the factory default mode of the switch.

The commands to change and display current the forwarding table mode are:
- Change to Mobile First Mode: platform forwarding-table-mode 3
- Return to Router Mode: platform forwarding-table-mode 4
Notes:
- these commands run in user mode (outside the configure context)
- the system will reboot to operate in a different mode
Example
8320-01# show platform forwarding-table-mode
Mode L2 Entries Host Entries Route Entries

8320-01# platform forwarding-table-mode 3
This command requires a reboot to take effect.
