7 Network Management
7.1 Simple Network Management Protocol (SNMP)
The simple network management protocol (SNMP) is an application-layer protocol
designed to facilitate the exchange of management information between network devices.
SNMP consists of three parts: an SNMP manager, a managed device and an SNMP
agent. SNMP provides a message format for sending information between SNMP
manager and SNMP agent. The agent and MIB reside on the switch. In configuring SNMP
on the switch, you define the relationship between the manager and the agent. According
to community, you can give right only to read or right to both read and write. The SNMP
agent has MIB variables to reply to requests from SNMP administrator. In addition, SNMP
administrator can obtain data from the agent and save data in the agent. The SNMP
agent gets data from MIB, which saves information on system and network.
SNMP agent sends a trap to administrator for specific cases. Trap is a warning message
to alert network status to SNMP administrator.
The V5808 enhances access management of SNMP agent and limits the range of OID
opened to agents.
