In the CLI
To configure a Gigabit Ethernet port:
(host)(config) #interface gigabitethernet <slot>/<module>/<port>
(host)(config-if) #switchport mode trunk
(host)(config-if) #switchport trunk native vlan <id>
To confirm the port assignments, use the show vlan command:
(host) (config) #show vlan
Configuring the Default Gateway
The following configurations assign a default gateway for the controller.
In the WebUI
To configure the default gateway:
1. Navigate to Configuration > Network > IP > IP Routes.
2. To add a new static gateway, click the Add button below the static IP address list.
a. In the IP Address field, enter an IP address in dotted-decimal format.
b. In the Cost field, enter a value for the path cost.
c. Click Add.
3. You can define a dynamic gateway using DHCP, PPPOE or a cell uplink interface. In the Dynamic section,
click the DHCP, PPPoE or Cellular checkboxes to select one or more dynamic gateway options. If you select
more than one dynamic gateway type, you must also define a cost for the route to each gateway. The
controller will first attempt to obtain a gateway IP address using the option with the lowest cost. If the
controller is unable to obtain a gateway IP address, it will then attempt to obtain a gateway IP address using
the option with the next-lowest path cost.
4. Click Apply.
In the CLI
To configure the default gateway:
ip default-gateway <ipaddr>|{import cell|dhcp|pppoe}|{ipsec <name>} <cost>
Configuring the Loopback IP Address for the Controller
You must configure a loopback address if you are not using a VLAN ID address to connect the controller to the
network (see Deployment Scenario #3: APs on Multiple Different Subnets from Controllers on page 103).
After you configure or modify a loopback address, you must reboot the controller.
If configured, the loopback address is used as the controller’s IP address. If you do not configure a loopback
address for the controller, the IP address assigned to the first configured VLAN interface IP address. Generally,
VLAN 1 is configured first and is used as the controller’s IP address.
ArubaOS allows the loopback address to be part of the IP address space assigned to a VLAN interface. In the
example topology, the VLAN 5 interface on the controller was previously configured with the IP address
10.3.22.20/24. The loopback IP address in this example is 10.3.22.220.
You configure the loopback address as a host address with a 32-bit netmask. The loopback address should be
routable from all external networks.
