Once the authentication parameters are configured, you use the
set
authentication
command to enable authentication for a specified tunnel.
Configuring a Tunnel
Group Name
/protocol/te-<eng>/set tunnel <index (1-5)>
group-name <group_name>
The <group_name> parameter indicates that an LNS belongs to a particular
group.
The BelView NMS tunnel manager looks at the tunnel usage of all LNSs within
the same group and spread the tunnel traffic among the LNSs within the same
group. BelView also configures tunnels for newly introduced nodes to the least
used LNS within the same group.
For details, refer to the
BelView NMS User Guide
.
Relaying Traffic QOS
Settings
/protocol/te-<eng>/set tunnel <index (1-5)>
qos-map {none|up-bits|dscp)
Because the BelAir AP converts the client data packet into an Ethernet frame
and then encapsulates it within an IP packet, any QOS information that was part
of the original client data packet is not visible to upstream equipment.
This command allows you to put the QOS information into the encapsulating IP
packet header so that it becomes visible to the upstream equipment:
• The
dscp
setting means that Differentiated Services Code Point (DSCP)
information from the client data packet is included in the IP packet header.
• The
up-bits
settings means that the IP packet header contains QOS settings
based on User Priority bits (0 to 7) from the client data packet.
• The
none
setting means that QOS information from the client data packet is
not sent to upstream equipment.
The default setting is
none
.
Setting the Tunnel
Down Alarm Threshold
/protocol/te-<eng>/set alarm-threshold
{disabled | enabled <num_of_alarms>}
Typically, a
Tunnel Down
alarm is generated when a tunnel fails to respond.
However, if there are intermittent issues with the tunnel, it may take time to
identify and correct the root cause. During this period, multiple
Tunnel Down
alarms would be generated.
Enabling the alarm threshold reduces the number of
Tunnel Down
alarms
generated per calendar day. If the threshold is reached, the system generates
