Heartbeat IP address:
This parameter specifies the destination IP address for heartbeat packets.
Heartbeat selects interface from routing table:
When enabled, the UDP heartbeats will choose the best route from the routing table. If disa-
bled the exit interface will be interface on which the heartbeat is configured.
Heartbeat includes IMSI:
When enabled, the heartbeat will include the IMSI of the wireless module.
Physical link down deact delay (s):
This parameter is used to specify the length of time (in seconds) that the router will wait after
detecting that an Ethernet cable has been removed before routes that were using that interface
are marked as out of service. If the parameter is set to 0, the feature is disabled i.e. routes using
the port will not be marked as out of service if the cable is removed.
Enable Top Talker Monitoring:
If this parameter is set to “Yes”, Top Talker information is logged and displayed on the Statistics
> Top Talkers page. Top Talkers displays average bandwidth usage for the interface over three
time frames: current, previous minute, and previous 30 minutes.
VRRP group ID:
The VRRP parameters are used to configure the router to participate in a VRRP group. VRRP
(Virtual Router Redundancy Protocol), allows multiple physical routers to appear as a single
gateway for IP communications in order to provide back-up WAN communications in the event
that the primary router in the group fails in some way. It works by allowing multiple routers to
monitor data on the same IP address. One router is designated as the “owner” of the address
and under normal circumstances it will route data as usual. However, the VRRP protocol allows
the other routers in the VRRP group to monitor the “owner” and if, they detect that it is no
longer operating, negotiate with each other to take over the role as owner. The protocol also
facilitates the automatic re-prioritisation of the original owner when it returns to operation.
The VRRP group ID parameter is used to identify routers that are configured to operate within
the same VRRP group. The default value is 0 which means that VRRP is disabled on this Ethernet
port. The value may be set to a number from 1 to 255 to enable VRRP and include this Ethernet
port in the specified VRRP group.
VRRP priority:
This parameter is used to set the priority level of this Ethernet interface within the VRRP group
from 0 to 255. 255 is the highest priority and setting the priority to this value would designate
this Ethernet port as the initial “owner” within the group. The value selected for the VRRP
priority should reflect the values selected for other routers within the VRRP group, i.e. no two
routers in the group should be initialised with the same value.
VLAN:
If this parameter is set to “On”, VLAN tagging is enabled on this interface according to the
parameters set on the Configure > Ethernet > VLANs page. VLAN tagging will only apply if
there is an entry for this interface on the Configure > Ethernet > VLANs page.
