standby use-interface Appendix A Cisco 3825 Mobile Wireless Edge Router RAN-O Command Reference standby use-interface To designate a loopback interface as a health or revertive interface, use the standby use-interface command in y-cable configuration mode. standby use-interface interface {health | revertive | backhaul} Syntax Description interface health revertive backhaul Interface to be used with the specified parameter. For health and revertive, this is the loopback interface that is specified in the standby track command. For backhaul, the interface must be an MLPPP interface. If you want to use a serial interface as the backhaul, you must first configure that interface to be part of an MLPPP bundle. Interface that will the router for an overtemperature condition, the state of the processor, and the state of the T1/E1 firmware. If any of these conditions indicates a failure, this interface is brought down. Otherwise, the health interface remains in the up state. Interface that acts as the revertive interface. If the Cisco 3825 router changes state from active to standby, the revertive interface is brought up. If the router changes state from standby to active, the revertive interface is brought down. Interface to be used for backhauling. Defaults By default, the Cisco 3825 is configured to be used in a redundant configuration (no standalone) and the relays are open. Command Modes Y-cable configuration Command History Release 12.2(8)MC2 Modification This command was introduced. Usage Guidelines The loopback interfaces that you specify for the health and revertive interfaces must be the same loopback interfaces that you specified in the standby track command. In the standby track command, the decrement value for the revertive interface should always be less than that for other interfaces. We recommend that you use loopback101 for health and loopback102 for revertive. The interface that you specify for the backhaul must be an MLPPP interface. If you want to use a serial interface as the backhaul, you must first configure that interface to be part of an MLPPP bundle. We recommend you that use multilink1 for the backhaul interface.
