Configuring the Default Gateway
The following configurations assign a default gateway for the switch.
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
switch will first attempt to obtain a gateway IP address using the option with the lowest cost. If the switch 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 Switch
You must configure a loopback address if you are not using a VLAN ID address to connect the switch to the
network (see Deployment Scenario #3: APs on Multiple Different Subnets from Switches on page 37).
After you configure or modify a loopback address, you must reboot the switch.
If configured, the loopback address is used as the switch’s IP address. If you do not configure a loopback
address for the switch, the IP address assigned to the first configured VLAN interface IP address. Generally,
VLAN 1 is configured first and is used as the switch’s IP address.
AOS-W 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 switch 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.
Spanning tree protocol (STP) is enabled by default on the switch. STP ensures a single active path between any
two network nodes, thus avoiding bridge loops. Disable STP on the switch if you are not employing STP in your
network.
In the WebUI
To configure a loopback IP address:
1. Navigate to Configuration > Network > Switch > System Settings.
