Power Level Difference

We have some 3600 APs and we see a difference in number of supported Power levels on 802.11b-2.4Ghz Radio on each channel.

Channel 6 and 11 have 8, where as channel 1 has just 7:

   Tx Power
          Num Of Supported Power Levels ............. 7
    Current Channel ........................... 1

   Tx Power
          Num Of Supported Power Levels ............. 8
    Current Channel ........................... 6

   Tx Power
          Num Of Supported Power Levels ............. 8
    Current Channel ........................... 11

Is this an issue or by design? This we don't see on other AP's.

It varies with AP model, but

It varies with AP model, but it's really nothing to worry about.  If you go into the cli of the WLC, you can issue the show advanced 802.11b txpower and that will give you a listing of the max and min.  This can be used to look at the 5ghz also.

AP Name                          Channel    TxPower       Allowed Power Levels    
-------------------------------- ---------- ------------- ------------------------
AP801AGN-A-K9                    *6         *4/5 (11 dBm) [17/15/14/11/8/0/0/0]
AIR-CAP3602I-01                   *1         *4/7 (13 dBm) [22/19/16/13/10/7/4/4]
AIR-CAP3602I-02                   *11         1/8 (23 dBm) [23/20/17/14/11/8/5/2]
AIR-CAP3602E-03                 *11        *2/8 (20 dBm) [23/20/17/14/11/8/5/2]
