Table 140 Configuration items
Item Description
Mesh Policy Display the name of the created mesh policy.
Link establishment
By default, link initiation is enabled.
IMPORTANT:
• Disable this feature when you configure an MP policy for a rail
AP.
• This function can only be disabled on train MPs in subway
WLAN mesh deployment.
Minimum time to hold a link
Set the link hold time.
An active link remains up within the link hold time, even if the link
switch margin is reached. This mechanism is used to avoid
frequent link switch.
Maximum number of links
Set the maximum number of links that an MP can form in a mesh
network.
IMPORTANT:
When configuring mesh, if the number of mesh links configured on
an AP is greater than two, you need to configure the maximum links
that an MP can form as needed.
Minimum rssi to hold a link
Set the link formation/link hold RSSI (received signal strength
indicator).
This is the minimum RSSI to allow a link to be formed and held.
Therefore, the minimum RSSI must be used at any given point in
the tunnel. Otherwise, the error rate can be very high.
Minimum margin rssi
Set the link switch margin.
If the RSSI of the new link is greater than that of the current active
link by the link switch margin, active link switch will occur. This
mechanism is used to avoid frequent link switch.
Maximum rssi to hold a link
Set link saturation RSSI.
This is the upper limit of RSSI on the active link. If the value is
reached, the chipset is saturated and link switch will occur.
Interval between probe requests Set the probe request interval.
Role as authenticator
By default, whether or not a device plays the role of an
authenticator is based on negotiation results.
ratemode
• fixed—This is the default mode. The rate adopted is of a fixed
value. It is the maximum rate of the current radio.
• realtime—The rate adopted changes with the link quality. The
rate changes with the change of the RSSI of the current radio.
The Mobile Link Switch Protocol (MLSP) implements high-speed link switch with zero packet loss during train
movement. It is only applicable to subway WLAN mesh deployment.
Proxy MAC Address
Select the Proxy MAC Address option to specify the MAC address
of the peer device.
Proxy VLAN VLAN ID of the peer device.
