Versatile Routing Platform

Configuration of Backup Center

If the main interface is a virtual circuit, it should be treated differently depending on the type of the virtual circuit: firstly, specify its logical channel number in the configuration mode of the physical interface to which it’s subordinate; then enter corresponding logical channel configuration mode. logic-channel-numberranges between 0 to 255.

Please use following commands in corresponding configuration modes.

1.2.3 Specifying Backup Interface and Priority Used by the Main Interface

Except Ethernet interface, any physical interface or virtual interface template, or a certain logical channel (including virtual circuit or Dialer Map) can work as a backup interface of the main interface. Please use the following commands in the configuration mode of the main interface backed up.

Command

 

 

Specify a physical interface or virtual interface template, except

number [priority]

Here, interface-type interface-number specifies a physical interface or virtual interface template; the value range of logic-channel-number is 1~255; the value range of priority of the backup interface is 0~255, with 0 as default. The larger the value, the higher the priority, i.e., when the main interface gets faulty, its work will be first taken over by an interface with the highest priority.

If the main interface has multiple backup interfaces, simply repeat the above operations. In addition, if the backup interface is a logical channel, the logical channel should be made to correspond to the actual virtual circuit or Dialer Map.

Please use the commands below to specify corresponding logical channel numbers for these virtual circuits or Dialer Map in the configuration mode of the physical interface to which they are subordinate.
