• If the system egress point is set to
indirect
with a gateway IP address, then
the base station pings the gateway IP address and starts the out-of-service
timer if it does not receive a reply. If the timer expires and the gateway still
does not reply, then the base station is taken out of service by prepending
bsOutOfService
to the mobile link identifier.
Release 7 Compatibility
/services/mobility/set release-7-compatibility {true|false}
This command lets you connect a subscriber station to a base station running
Release 7.1.0 software.
Single Channel Mesh
/services/mobility/set single-channel-mesh ([channel <chan_no>]
[link-id <link_id>]
[privacy {{enabled key <random_str>}|disabled}]
[allow-multi-links {yes|no}])
Normally, BelAir units create a wireless mesh between themselves using
multiple radio channels to avoid radio interference. However, in some mobile
applications, in may be desirable to have all radios use a single channel. Such an
application requires that all radios use directional antennas and are correctly
positioned to avoid radio interference.
This command allows you to configure such an application, where all radios use
a single channel. This command must be invoked on each node in the mesh.
The
<chan_no>
parameter allows you to specify which channel to use.
The
<link_id>
parameter is case sensitive and can be up to 32 alphanumeric
characters. BelAir Networks recommends that the link identifier describes the
link; that is, the nodes it connects.
The
privacy
setting determines whether AES privacy is used or not.
The pre-shared key must be exactly 32 bytes long (16 characters). The
pre-shared key can be specified as a hexadecimal or ASCII string and must not
contain the following characters:
• bar (|)
• semicolon (;)
• question mark (?)
• double quotation mark (“)
The
allow-multi-link
setting determines whether both a primary and secondary
links are created between each node in the mesh or just a primary. Multiple
links increase redundancy, but in a single channel mesh application may limit the
number of inter-connected nodes. The default is
no
.
