Multi Service Border Gateway User Manual for NexusWay 800 Series
4-1-2-g. Failover Configuration
The automatic disconnect detection mechanism is activated when NexusWay 800 connects to
a WAN. Administrators will receive the warning if the WAN is disconnected. You can set up the
detection policies here to reduce the possibility of erroneous judgment. This configuration is
available for every connection that is setup.
TTL: Hops
You can choose "TTL: Hops" to trace a network node (router) and to detect network
disconnections by "Traceroute". Enter the number of node you want to detect, before
assuming failure.
Ping: Host IP
You can also determine if the network is working normally by Pinging an IP address. Ensure
the host you want to ping to test for network connection detection is open and enter its IP
addresses in the Host IP column.
Connect: Host IP: port
If pinging is not supported by the remote computer system, enter IP address and port number
of the host you want to connect.
Retry Times
Enter the number of continuous retry attempts when Host IP or TTL address is detected as not
responding. This means, that if you set this to 3 times; when the Host IP or TTL address is
detected as not responding for more than three attempts, the system will determine the line is
disconnected.
Interval of Detection (sec)
Enter the interval time in seconds for contacting IP addresses or checking TTLs.
