Or Device Resynchronization Fails - Alcatel-Lucent 5620 Troubleshooting Manual

Additional devices cannot be managed, but can be discovered, when the license key
card (MDA) limit is exceeded. When an incorrect license key is entered during
installation or the license key file is corrupt, you can correct it.

Procedure 10-10 Problem: Cannot discover more than one device,

or device resynchronization fails

Consider the following:
Alcatel-Lucent 5620 Service Aware Manager, Release
3HE 05723 AAAD TQZZA Edition 01
Caution — Do not modify other nms-server.xml parameters. Modifying
the file can seriously affect network management and performance of
the 5620 SAM.
Check the license-key status.
i The 5620 SAM generates an alarm when a license limit is exceeded or nearly
exceeded. View the dynamic alarm list on the 5620 SAM client GUI, or the
JMS real-time alarm feed from the 5620 SAM OSS client application for alarms
related to nearing or exceeding a license limit.
ii Choose Help→5620 SAM License Information from the 5620 SAM client GUI
main menu. The 5620 SAM License (View) form opens.
iii View the information in the Devices and Quantities Licensed panel and
ensure that no Remaining quantity equals zero.
Note — If you have a new license key that supports a greater number
of managed objects, you can dynamically update the license key
without shutting down the server. See the 5620 SAM User Guide for
information about changing a 5620 SAM license key.
Specific ports need to be available for the 5620 SAM server. Check the
Alcatel-Lucent 5620 SAM Planning Guide for more information about which ports
need to be available.
The 5620 SAM-managed devices are configured to send SNMP packets of up to 9216
bytes. Check the MTU size, as described in Procedure 7-4.
When using SNMPv3 encryption, the engine ID of the managed device must be
•
unique. As well, SNMP issues may result in Polling Problem alarms. Otherwise,
the following issues may occur:
unreliable or slow discovery of network devices
•
resynchronization during scheduled polling fails
•
slow communication and synchronization times
•
polling fails completely
•
When 5620 SAM resynchronizes some functions on a node, for example, BGP
•
configurations for the 7750 SR, the SNMP packets may be broken into two or
more smaller packets, when the maximum PDU size of 9126 bytes is exceeded.
