Alcatel-Lucent 5620

These mechanisms are built into the Alcatel-Lucent 7950, 7750, 7450, 7710, 7210, and

7705 Network Elements and the 5620 SAM network element interaction layers.

IP connectivity (ping) verification

5620 SAM can be configured to ping all network elements at a configurable interval to

monitor IP connectivity. If the network element is unreachable, an alarm will be raised

against the network element. Details of the alarm are the following:

• Severity: Critical

• Type: communicationsAlarm

• Name: StandbyCPMManagementConnectionDown, OutOfBandManagementConnec-

tionDown or InBandManagementConnectionDown

• Cause: managementConnectionDown.

Ping verification is disabled by default. IP connectivity checks using ping must be

scheduled through the default policy.

SNMP connectivity verification

5620 SAM performs an SNMP communication check every 4 minutes. If 5620 SAM can

not communicate via SNMP with a network element, 5620 SAM will raise a

communications alarm against that network element. 5620 SAM will also color the

network element red on the map to indicate the communication problem. 5620 SAM will

clear the alarm and color the network element as green once 5620 SAM detects SNMP

connectivity to the network is re-established. Details of the alarm are the following:

• Severity: Major

• Type: communicationsAlarm

• Name: SnmpReachabilityProblem

• Cause: SnmpReachabilityTestFailed

This behavior occurs by default and is not configurable.
