Simple Network Management Protocol (SNMP) Proxy Agent
In order to communicate to the Higher Level Managers (HLM), that is the IDM and/or the OSS, FOXMAN-UN provides an SNMP proxy agent as a licensed option. This proxy agent provides a mediation device function for fault management, based on SNMP v1/v2c/v3.
Using the trap mechanism of SNMP, FOXMAN-UN informs the HLM about the following:
• Information on alarms (new, outstanding, acknowledged and cleared alarms), which includes the alarm text, identification, time and date of alarm, and the severity;
• Notification of the addition and deletion of network elements and units within it;
• Changes in operational state of the network element.
The possibility for sending traps to two different HLM systems is supported. This is required in a redundant system, where one HLM system protects the other one.
A standard SNMP «get» request from the HLM provides inventory information such as the lists of installed NEs and their configured units.
