To ensure management continuity, you can configure the device to monitor the NMS connected interface for IP address changes and notify the NMS to update with the new IP address for communicating with the device.

You can configure one primary and one secondary interface for the device to communicate with the NMS, but the device monitors only one of them for IP address change at one time. If the IP address of the monitored interface in UP state changes, whether because of manual reassignment or DHCP reassignment, the device notifies the NMS of the new IP address. The IP address changes of the interface not under monitor will be ignored.

The device preferentially monitors the primary interface. HP recommends you specify the interface that has better route or more reliable link as the primary.

The device changes the monitored interface only when the interface goes down, the interface IP address is deleted, or the role of the interface is removed by using the undo nms { primary secondary } monitor-interface command.

Before you specify NMS-connected interfaces, make sure you have configured the NMS as the SNMP notification destination host. For more information about SNMP, see System Management and Maintenance Configuration Guide.

To monitor NMS-connected interfaces:

Step

Command

Remarks

1. Enter system view.

system-view

N/A

2.Specify NMS-connected interfaces.

•Specify the primary interface: nms primary monitor-interface interface-typeinterface-number

•Specify the secondary interface: nms secondary monitor-interface interface-typeinterface-number

Configure at least one command.

By default, no interfaces are configured as NMS-connected interfaces to be monitored.

The monitoring function only applies to interfaces that use IPv4 addresses.

Clearing unused 16-bit interface indexes

The device must maintain persistent 16-bit interface indexes and keep one interface index match one interface name for network management. After deleting a logical interface, the device retains its 16-bit interface index so the same index can be assigned to the interface at interface re-creation.

To avoid index depletion causing interface creation failures, you can clear all 16-bit indexes that have been assigned but not in use. The operation does not affect the interface indexes of the interfaces that have been created but the indexes assigned to re-recreated interfaces might change.

A confirmation is required when you execute this command. The command will not run if you fail to make a confirmation within 30 seconds or enter N to cancel the operation.

To clear unused 16-bit interface indexes, execute one of the following commands in user view:
