Finding Guard Interval setting

[jturner2720]

Hi,

I can see various instructions for setting the guard interval through the CLI, but nothing for showing it. I can't see anything jump out at me doing a show run or any sort of command for showing it specifically.

If there's nothing there, is there a documentation saying what the default values are? 400ns with a compatible client and 800ns otherwise? Or something else?

Thanks.

You can show it by entering show 802.11b or show 802.11a.
Line looks like this:
Guard Interval .............................. Any
If it's set to any, it defaults to 400ns for compatible clients.
You can change it like this:
(Cisco Controller) >config 802.11b 11nSupport guard_interval ?

any Enable 802.11n-2.4Ghz any to allow either short or long guard interval
long Enable 802.11n-2.4Ghz long guard interval
