Release Notes for Cisco Aironet Access Points and Bridges for Cisco IOS Release 15.2(2)JA

OL-23990-01

Important Notes

Cisco 7920 Phones Require Firmware Version 1.09 or Later When Multiple

BSSIDs Are Enabled

When multiple BSSIDs are configured on the access point, Cisco 7920 wireless IP phones must run

firmware version 1.09 or later.

GRE Tunnelling Through WLSM Sometimes Requires MTU Setting Adjustments

If client devices on your wireless LAN cannot use certain network applications or cannot browse to

Internet sites, you might need to adjust the MTU setting on the client devices or other network devices.

TACACS+ and DHCP IP Address Sometimes Locks Out Administrators

When you configure an access point for TACACS+ administration and to receive an IP address from the

DHCP server, administrators might be locked out of the access point after it reboots if the administrator

does not have a local username and password configured on the access point. This issue does not affect

access points configured with a static IP address. Administrators who have been locked out must regain

access by resetting the unit to default settings.

Access Points Do Not Support Loopback Interface

You must not configure a loopback interface on the access point.

Caution Configuring a loopback interface might generate an IAPP GENINFO storm on your network and disrupt

network traffic.

Non-Cisco Aironet 802.11g Clients Might Require Firmware Upgrade

Some non-Cisco Aironet 802.11g client devices require a firmware upgrade before they can associate to

the 802.11g radio in the access point. If your non-Cisco Aironet 802.11g client device does not associate

to the access point, download and install the latest client firmware from the manufacturer’s website.

Throughput Option for 802.11g Radio Blocks Association by 802.11b Clients

When you configure the 802.11g access point radio for best throughput, the access point sets all data

rates to basic (required). This setting blocks association from 802.11b client devices. The best

throughput option appears on the web-browser interface Express Setup and Radio Settings pages and

in the speed CLI configuration interface command.
