Through the RJ45 console port, you can make a serial connection between your management system and
the AP. The pin-to-signal mapping of the RJ45 console port is shown in Figure 2 on page 7.
Aggregate and Redundant Interfaces
By default ETH0 and ETH1 act as two individual Ethernet interfaces. When both interfaces are connected
to the network and are in backhaul mode, the AP transmits broadcast traffic only through ETH0. The AP
transmits broadcast traffic through ETH1 only when ETH0 does not have network connectivity. When both
Ethernet interfaces are connected to the network and are in access mode, then the AP transmits
broadcast traffic through all the access interfaces: ETH0, ETH1, and all wireless subinterfaces in access
mode.
In addition to using ETH0 and ETH1 as individual interfaces, you can combine them into an aggregate
interface (agg0) to increase throughput, or combine them into a redundant interface (red0) to increase
reliability. The logical red0 and agg0 interfaces support all the settings that you can configure for
Ethernet interfaces except those pertaining to physical link characteristics such as link speed. See the
sections below for configuration information.
Aggregate Interface
You can increase throughput onto the wired network by combining ETH0 and ETH1 into a single logically
aggregated interface called "agg0". The aggregate interface effectively doubles the bandwidth that
each physical interface has when used individually. In this configuration, both Ethernet ports actively
forward traffic, the AP applying an internal scheduling mechanism based on the source MAC address of
each packet to send traffic through the aggregate member interfaces. To configure an aggregate
interface, enter the following commands:
interface eth0 bind agg0
interface eth1 bind agg0
In addition to configuring the AP, you must also configure the connecting switch to support
EtherChannel. For example, the following commands bind two physical Ethernet ports—0/1 and 0/2—to
the logical interface port-channel group 1 on a Cisco Catalyst 2900 switch running Cisco IOS 12.2:
Switch#conf t
Switch(config)#interface port-channel 1
Switch(config-if)#switchport mode access
Switch(config-if)#spanning-tree portfast
Switch(config-if)#exit
Switch(config)#interface fastEthernet 0/1
Switch(config-if)#switchport mode access
Switch(config-if)#channel-group 1 mode on
Switch(config-if)#spanning-tree portfast
Switch(config-if)#exit
Switch(config)#int fastEthernet 0/2
Switch(config-if)#switchport mode access
Switch(config-if)#channel-group 1 mode on
Switch(config-if)#spanning-tree portfast
Switch(config-if)#exit
Switch(config)#exit
Switch#wr mem
Finally, you must cable the Cisco switch and the AP together: Cisco 0/1 to AP eth0, and Cisco 0/2 to AP
eth1.
