Any Network Management System (NMS) running the Simple Network Management
Protocol (SNMP) can manage the Managed devices equipped with SNMP agent, provided
that the Management Information Base (MIB) is installed correctly on the managed devices.
The SNMP is a protocol that is used to govern the transfer of information between SNMP
manager and agent and traverses the Object Identity (OID) of the management Information
Base (MIB), described in the form of SMI syntax. SNMP agent is running on the switch to
response the request issued by SNMP manager.
