Configuration of Backup Center
1-2
If the main interface is a virtual circuit, it should be treated diff erently 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 correspond ing
logical channel configuration mode. logic-channel-number ranges between 0 to 255.
Please use following commands in corresponding configuration m odes.
Table LC-1-2 Enter the logical channel configuration mode
Operation Command
Specify logical channel number for X.25 virtual circuit. x25 map protocol address x.121-address lin logic-
channel-number [ lin logic-channel-number ... ]
Specify logical channel number for frame relay virtual
circuit frame-relay map protocol address dlci lin logic-
channel-number [ lin logic-channel-number ... ]
Enter corresponding logical channel configuration mode. logic-channel logic-channel-number
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) c an work as a back up
interface of the main interface. Please use the following comm ands in the configuration
mode of the main interface backed up.
Table LC-1-3 Specify backup interface and priority used by the main interface
Operation Command
Specify a physical interface or virtual interface template, except
Ethernet interface, to back up the main interface; its priority can
also be set here.
backup interface interface-type interface-
number [priority]
Specify a logical channel to back up the main interface, its priority
can also be set here. backup logic-channel logic-channel-
number [priority]
Here, interface-type interface-number specifies a physical interface or virt u al interface
template; the value range of logic-channel-number is 1~255; t he 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 a bove operations.
In addition, if the backup interface is a logical channel, the logical c hannel shoul d 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 ph ysical interface to
which they are subordinate.
