Finally, you must cable the Cisco switch and the SmartPath AP together: Cisco 0/1 to SmartPath AP eth0, and Cisco 0/2 to
SmartPath AP eth1.
Redundant Interface
If a single Ethernet link provides sufficient bandwidth and speed, such as a 1000-Mbps link, but you want to ensure link redun-
dancy, you can connect the two Ethernet ports to the same switch—or to two different switches—and configure them to act as
a redundant interface called "red0". In this mode, only one Ethernet interface is actively forwarding traffic at any one time. If eth0
is active and eth1 is passive and eth0 loses its connection, the SmartPath AP switches over to eth1. To configure a redundant
interface, enter the following commands:
interface eth0 bind red0 primary
interface eth1 bind red0
The interface that you specify as primary is the one that the SmartPath AP uses when both interfaces have network connectivity.
Because the SmartPath AP uses eth0 as the primary interface by default, it is unnecessary to specify "primary" in the first
command above. However, it is included to make the role of eth0 as the primary interface obvious.
NOTE: No extra configuration is necessary on the connecting switch or switches to support a redundant interface.
Interface Selection for the Default Route
In cases where there are multiple active interfaces in backhaul mode, the SmartPath AP uses the following logic to choose which
interface to use in its default route:
• If there is an Ethernet interface and a wireless interface in backhaul mode, the SmartPath AP uses the Ethernet interface in its
default route.
• If there are multiple Ethernet interfaces in backhaul mode, the SmartPath AP chooses which one to use in its default route in
the following order:
- It uses red0 or agg0 if one of them has at least one member interface bound to it and its link state is UP.
- It uses ETH0 if neither red0 nor agg0 has any member interfaces and the link state for ETH0 is UP.
- It uses ETH1 if neither red0 nor agg0 has any member interfaces, the link state for ETH0 is DOWN, and the link state for ETH1 is
UP.
