Chapter 29: Internet Protocol Version 4 Routing Interfaces
556 Section VII: Internet Protocol Routing
Setting the Default Route or Default Gateway
If you are configuring an AT-9400 Switch that supports IPv4 packet
routing, such as the AT-9424Ts and AT-9448Ts/XP switches, you can
configure the default route from the menus interface. The default route is
used by the switch when it receives a network packet for routing, but
cannot find a route for it. To create a default route, you specify the IP
address of the next hop for those packets without a route in the switch’s
routing table.
For an AT-9400 Switch that does not support the IPv4 packet routing
feature, such as the AT-9424T/GB and AT-9424T/SP switches, you can
define the default gateway from the menus interface. The default gateway
is the IP address of a router interface on your network. The switch’s
management software uses this address as the next hop to reaching a
remote network device, such as a remote management workstation or a
syslog server, when the switch’s local interface and the remote device are
on different subnets.
To set the default route or default gateway of the switch, perform the
following procedure:
1. From the Main Menu, type 5 to select System Administration.
2. From the System Administration menu, type 2 to select System
Configuration.
The System Configuration menu is shown in Figure 2 on page 33. The
current default route or default gateway is displayed in Selection 4,
Default Gateway. This selection contains 0.0.0.0 if no default route or
default gateway is defined on the switch.
3. In the System Configuration menu, type 4 to select Default Gateway.
The following prompt is displayed:
Enter IP Address:
4. Enter the IP address of the next hop for the default route or default
gateway.
The IP address must be a member of a subnet on the switch that has a
routing interface.
5. To permanently save your change, return to the Main Menu and type S
to select Save Configuration Changes.
