IOS Root and WGB Connectvity

Hi Experts,

What are the implications of blocking band 3 between a WGB and Root using the "dfs band 3 block" command. Note, this is enabled by default on IOS AP's as stated below. Does it in anyway affect the use of 802.11n MCS rates?

The 1, 2, 3, and 4 options designate blocks of channels:

1—Specifies frequencies 5.150 to 5.250 GHz. This group of frequencies is also known as the UNII-1

band.

2—Specifies frequencies 5.250 to 5.350 GHz. This group of frequencies is also known as the UNII-2

band.

3—Specifies frequencies 5.470 to 5.725 GHz. By default, this group of channels is blocked from

DFS selection.

4—Specifies frequencies 5.725 to 5.825 GHz. This group of frequencies is also known as the UNII-3

band.

This is the command that appears in a default configuration:

ap(config-if)# dfs band 3 block

Best Regards,

John

Re: IOS Root and WGB Connectvity

It doesn't affect MCS rates. Those channels are uni-2 extended which many devices don't support these days. That is fine not being used. Better that way:)
