Clearing Unused 16-Bit Interface Indexes - HP 830 Series Configuration Manual

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, see Network Management and Monitoring
Configuration Guide.
To monitor NMS-connected interfaces:
Step
1. Enter system view.
2. Specify NMS-connected
interfaces.

Clearing unused 16-bit interface indexes

For network management, the device maintains persistent 16-bit interface indexes and does not
automatically remove interface name and interface index mappings once they are created. 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:
Task
Clear unused 16-bit interface indexes.
Command
system-view
•
Specify the primary interface:
nms primary monitor-interface
interface-type interface-number
•
Specify the secondary
interface:
nms secondary
monitor-interface
interface-type interface-number
Command
reset unused porttag
116
Remarks
N/A
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.
