Usage guidelines
This command is only effective on 802.11n radios.
If you change the radio type of an 802.11n radio, the default setting for this function of the new radio type
is restored.
Delays might occur during receiving radio signals due to factors like multi-path reception. Therefore, a
subsequently sent frame might interfere with a previously sent frame. The GI function is used to avoid such
interference.
The GI interval in 802.11a/g is 800 us. The short GI function can be configured for 802.11n. This can
shorten the GI interval to 400 ns, which increases the data speed by 10 percent.
Examples
# Disable the short GI function.
<sysname> system-view
[sysname] interface WLAN-Radio2/0
[sysname-WLAN-Radio2/0] undo short-gi enable
short-retry threshold
Use short-retry threshold to specify the maximum number of attempts to transmit a frame less than the
RTS threshold.
Use undo short-retry threshold to restore the default.
