7 Network Management

7.1Simple Network Management Protocol (SNMP)

Simple Network Management Protocol (SNMP) system is consisted of three parts: SNMP manager, a managed device and SNMP agent. SNMP is an application-layer protocol that allows SNMP manager and agent stations to communicate with each other. SNMP pro- vides 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 both to read and to write. The SNMP agent has MIB variables to reply to request from SNMP administrator. And SNMP administrator can ob- tain 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 trap to administrator for specific cases. Trap is a warning message to alert network status to SNMP administrator.

The hiD 6615 S223/S323 enhances accessing management of SNMP agent more and limit the range of OID opened to agents.
