Simple Network Management Protocol¶
The Simple Network Management Protocol (SNMP) service on TNSR provides a method through which the router can be monitored by a Network Monitoring System (NMS) or other software which supports SNMP.
SNMP presents information about the router to clients organized in an object identifier (OID) tree which is defined by Management Information Base (MIB) files. SNMP clients can access information by using a numerical OID or by using names looked up from MIB files.
The SNMP daemon currently supports the View-based Access Control Model (VACM). In this model, groups of communities are allowed access to SNMP information defined by views, which grant or limit their access.
Future versions of TNSR will support SNMPv3 for more secure access control.
The SNMP service will respond to requests from host OS management interfaces as well as TNSR interfaces, if allowed by ACLs.
Access to the SNMP service on UDP port 161 should be limited by ACLs so that only authorized management hosts are able to reach the service.
