Redundant Network Connection
IPCorder KNR-5016/5024/5032/5040 supports the Backup Network Interface function. This service prevents
disconnection from the network in case of failure of one of network routes (both network adapters of the IPCorder must
be connected). This can prevent unavailability of the IPCorder in case of unwanted removal of a network cable or switch
failure. To set up this service:
1) Connect the second network cable to your IPCorder (use network adapter number 2) and to the switch.
2) Go to the Nework tab in the web interface of the IPCorder:
• If Service mode is active – continue to the
Network
page and if needed set up the basic network settings.
• If Normal mode is active - go to the
Settings
menu in the upper part of screen, then select
Configuration – Network
and if needed set up the basic network settings.
3) Check the
Enable second network interface as backup
option in the
Backup Network Interface
section.
4) Choose method of the
Failure detection
:
•
Link (cable connected)
– this option detects disconnection of the network cable. If the cable from network adapter
no. 1 is removed, the connection through the network adapter no. 2 will be automatically activated and vice versa.
•
Network (ping address from the list)
– this option checks if there is any traffic running through the active
network adapter of the IPCorder. If no network traffic is detected, the connection through the backup network
adapter will be automatically activated. Type at least one IP address of the independent server to the
IP address
list
text field.
5) In the
Check Interval
text field, set the interval for checking availability of the connection, the default value is set
to 100 ms, the typed value is used for both types of failure detection.
6) Click the
Apply
button to confirm the settings (use buttons
Apply Changes
and
Restart
if Service mode is active).
Note: The Backup Network Interface function is active only in Normal mode. If you are using DHCP server to obtain an
IP address, it is possible that after the settings are confirmed, your IPCorder will temporarily obtain another IP address.
