Cisco 1400 Series Bridges

[Thomas Yarger]

All,

Quick question. I'm currently logged into the web interface of my 1400 Series Bridge. I'm looking at the Radio0-802.11A Network Interfaces settings section and under Data Rates I notice the 54.0Mb/sec is configured as enabled but not required. What's the difference? Thanks

•Mandatory—Clients must support this data rate in order to associate to an access point on the controller or your bridge

•Supported—Any associated clients that support this data rate may communicate with the access point using that rate. However, the clients are not required to be able to use this rate in order to associate.

•Disabled—The clients specify the data rates used for communication.

Tom,

GREAT QUESTION ..

So you have basic and enable rates also sometimes called mandatory and supported .

If you SAY 54 is basic then both sides need to be set to basic. If not they will not connect.

Madatory rates also have other meanings in the cisco world. Broadcast and Multicast is sent on the highest mandatory rates. While managment traffic is sent on the lowest mandatory rate.

NOTE:

The client must support the basic rate that you select or it cannot associate to the access point. If you select 12 Mbps or higher for the basic data rate on the 802.11g radio, 802.11b client devices cannot associate to the access point's 802.11g radio.

Does this help ?
