HP VPN Firewall Appliances Getting Started Guide

101
The device preferentially monitors the primary interface. HP recommends that 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:

Command Remarks
1. Enter system view.
system-view
N/A
2. Specify
NMS-connected
interfaces.
• Specify the primary interface:
nms primary monitor-interface
interface-type interface-number
• Specify the secondary interface:
nms secondary monitor-interface
interface-type interface-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:
Task Command
Clear unused 16-bit interface indexes.
reset unused porttag
Verifying and diagnosing transceiver modules
This section describes how to verify and diagnose transceiver modules.
Verifying transceiver modules
You can verify the genuineness of a transceiver module in the following ways:
• Display the key parameters of a transceiver module, including its transceiver type, connector type,
central wavelength of the transmit laser, transfer distance and vendor name.
