- Guard Interval
Set the guard interval. It can be one of the following values:
• 400—Short guard interval (SGI), which is 400 nanoseconds. The short guard interval can increase throughput, but it can also increase the error rate because of increased sensitivity to RF reflections. This is the default value for 5-GHz radio frequencies.
• 800—Normal guard interval, which is 800 nanoseconds. This is the default value for 2.4-GHz radio frequencies.
Explicitly configure the short guard interval for a 5-GHz radio band:
vEdge# show running-config wlan wlan 5GHz channel 36 guard-interval 400 interface vap0 ssid tb31_pm6_5ghz_vap0 no shutdown ! !
Command introduced in Viptela Software Release 16.3.
