Release Notes for Cisco Aironet 1300 Series Outdoor Access Point/Bridge for Cisco IOS Release 12.3(4)JA2
OL-8216-01
Caveats
The speed and duplex settings on the access point/bridge FastEthernet0 interface apply only to the link
between the access point/bridge port and port 0 on the power injector. They are entirely independent of
the speed and duplex settings used on the RJ45 port (port 1) on the power injector. Therefore, for best
performance, you should not change the port 0 default settings. The default settings result in a 100Mbps,
full-duplex configuration used on the link between the access point/bridge and the power injector switch.

full-duplex configuration used on the link between the access point/bridge and the power injector switch.
The connecting port (the port on the device connected to the power injector’s RJ45) must be set to half
duplex or (preferably) auto duplex. If it is set to auto-duplex, the power injector switch port should
negotiate full duplex. If it is set to half duplex, the power injector switch port falls back to half-duplex.
The connecting port must not be configured to full duplex. If it is, the power injector switch port fails to
negotiate full-duplex, falls back to half duplex, which causes a duplex mismatch.

The connecting port must not be configured to full duplex. If it is, the power injector switch port fails to

The following guidelines for setting Ethernet speed and duplex should always be observed:
•
The internal FastEthernet0 interface should always be set for speed auto and duplex auto regardless
of the settings of the device to which the external LAN port on the power injector is connected (the
connecting port).
of the settings of the device to which the external LAN port on the power injector is connected (the
connecting port).
•
The connecting port should always be set for one of the following:
–
100 Mbps, auto duplex (recommended)
–
100 Mbps, half duplex
–
10 Mbps, auto duplex
–
10 Mbps, half duplex
Note
Setting the port to 10 Mbps will most likely degrade throughput.
•
The connecting port should never be set to full duplex.
Failure to follow these guidelines will result in lost data due to late collisions, CRC errors, etc.

Open Caveats
These caveats are open in Cisco IOS Release 12.3(4)JA for the access point/bridge:
•
CSCeb52431—When logging into a TACACS+ server, access points sometimes send hundreds of
additional authentication requests to the server after a successful authentication.
additional authentication requests to the server after a successful authentication.
•
CSCsa53019—UDP traffic performance problem when using WEP.
When WEP is used with UDP traffic, a throughput input is experienced in the Ethernet interface. If
the show interface fastethernet 0 command is executed, throttle counters increase but no high CPU
or buffers failure occurs.

or buffers failure occurs.
•
CSCeh29970—EAP authentication appears to fail at reload when SSID configured with WPA+TKIP
with EAP-FAST as the authentication mechanism.
with EAP-FAST as the authentication mechanism.
An authentication failed message appears at the time of reload, but after a few seconds, the
authentication succeeds without any configuration change or change in the client’s profile.
