648CHAPTER 45: CONFIGURING A STANDBY CENTER

Specifying a Standby Interface and the Priority Used by the Main Interface

main interface is a physical interface or sub-interface, use the following commands in system view to enter the view of the interface.

Table 695 Enter the View of the Main Interface

Operation	Command
Enter the view of the main interface	interface type number

If the main interface is a virtual circuit, it should be treated differently depending on the type of the virtual circuit. First, specify its logic channel number in the view of the physical interface to which it is subordinate, then enter the corresponding logic channel view.

Use the following commands in the logical channel view.

Table 696 Enter the Logic Channel View

Operation	Command
Specify a logic channel number for an	x25 map protocol address x121-address
X.25 virtual circuit. (interface view)	x.121-address logic-channelnumber

(system view)

Any physical interface or logic channel, including a virtual circuit or dialer route, can work as a standby interface of the main interface.

Use the following commands in the view of the main interface.

Table 697 Specify Standby Interface and Priority Used by the Main Interface

Operation	Command
Specify a physical interface to back up the	standby interface type number [
main interface; its priority can also be set	priority ]
here.
Specify a logic channel to back up the	standby logic-channel number [
main interface, its priority can also be set	priority ]
here.

If one main interface has multiple standby interfaces, repeat these operations. In addition, if the standby interface is a logic channel, the logic channel should be made to correspond to the actual virtual circuit or dialer route.

Please perform the following tasks in the views of the physical interface to which the virtual circuit or the dialer route belongs, and specify the corresponding logic channel number.
