Document Number BDTM02201-A01 Standard
In the previous output, link 1 goes to RadioC and link 2 goes to RadioA.
RadioB is measuring a signal strength of -68 dBm from RadioC. As in example 1,
RadioC has a MAC address of 00:0d:67:0b:55:17 and is physical interface
wifi-3-1 on a node with IP address 180.1.5.120.
As in example 1, RadioB is measuring a signal strength of -54 dBm from RadioA.
RadioA has a MAC address of 00:0d:67:08:63:31 and is physical interface
wifi-4-1 on a node with IP address 180.1.5.180.
Example 3: Mobile Backhaul Mesh
/interface/wifi-1-1# show backhaul status
Backhaul Links:
Link Radio Mac State(L,R) RSSI Radio Node IP Node Name
----- ----------------- ---------- ---- ----- -------- ----------
[M] 1 00:0d:67:09:23:6a fwd fwd -68 wifi-3-1 10.1.1.123 NYC_WALLST
[M] 1 00:0d:67:00:08:06 fwd UP -71 wifi-3-1 10.1.1.122 NYC_BROADWAY
In the previous output, there are two mobile backhaul mesh links. One is
forwarding while the other is listening.
Setting a Link RSSI
Threshold
/interface/wifi-<n>-<m>/set backhaul mesh-min-rssi <rssi_value>
This command lets you set a signal strength threshold for creating mesh links. If
a radio signal from another node is weaker than the specified threshold, then
no link is created to that other node, except if there is no other link to either
node at each end of the link. In that case, the link is still created even if the
radio signal is weaker than the specified threshold.
This command applies only when a node is forming MP-to-MP links with other
nodes. Existing links are not affected by this command.
The
rssi_value
parameter is specified in as a negative number in dBm. The
default value is -100 dBm. Use the
show config backhaul
command to display
the current value.
Example
/interface/wifi-1-1# set backhaul mesh-min-rssi -70
The previous command sets the link RSSI threshold to -70 dBm. If the signal
from another radio is stronger than -70 dBm, then a backhaul link to that radio
is created. If it is weaker than -70 dBm, then a link is not created.
