Item Description
Dynamic Channel Select:
• Manual—Select one-time dynamic channel selection (DFS) and click
Apply to enable it. After manual mode is selected, if no mesh network is
manually specified when the next calibration interval is reached, the AC
will refresh radio information of all mesh networks that it manages, and
display it on the Radio Info tab of the Mesh Channel Optimize page. You
can view the radio information and select mesh networks for which
one-time DFS will be performed on the Mesh Channel Optimize tab. After
that, if you want the AC to perform DFS for the mesh network, you have
to make this configuration again.
• Auto—Select auto-DFS and click Apply to enable it. Auto-DFS applies to
all mesh networks where the working channels of the radios are
automatically selected. With auto DFS enabled, an AC makes DFS
decisions at the calibrate interval automatically.
• Close—Close DFS. At the next calibration interval, the radio information
and channel switching information on the Mesh Channel Optimize page
will be cleared.
By default, DFS for a mesh network is disabled.
IMPORTANT:
Before enabling auto or one-time DFS for a mesh network, make sure auto
mode is selected for the working channel of radios in the mesh network. For
the related configuration, see "Configuring radios."
Enabling mesh portal service

3. Select the AP for which mesh portal service is to be enabled.
4. Click Enable.
Configuring a working channel
You can configure a working channel by using one of the following methods.
No matter which method is used, as long as an AP detects radar signals on its working channel, the AP
and any other AP that establish a mesh link switch to another available working channel.
In some countries, most available channels on the 802.11a band are radar channels, so H3C
recommends that you use the auto mode to establish mesh links on the 802.11a band.
