Your V310 supports SNMP agent functionality, which allows a manager station to manage and monitor the V310 through the network. An SNMP managed network consists of two main components: agents and a manager. An agent is a management software module that resides in a managed device (the V310). An agent translates the local management information from the managed switch into a form compatible with SNMP. The manager is the console through which network administrators perform network management functions. It executes applications that control and monitor managed devices. The managed devices contain object variables/managed objects that define each piece of information to be collected about a switch. Examples of variables include number of packets received, node port status and so on. A Management Information Base (MIB) is a collection of managed objects. SNMP allows a manager and agents to communicate for the purpose of accessing these objects. SNMP itself is a simple request/response protocol based on the manager/agent model. The manager issues a request and the agent returns responses using the following protocol operations: Table 16 SNMP Commands COMMAND DESCRIPTION Get Allows the manager to retrieve an object variable from the agent. GetNext Allows the manager to retrieve the next object variable from a table or list within an agent. In SNMPv1, when a manager wants to retrieve all elements of a table from an agent, it initiates a Get operation, followed by a series of GetNext operations. Set Allows the manager to set values for object variables within an agent. Trap Used by the agent to inform the manager of some events. 82 V310 User's Guide

SNMP
Simple Network Management Protocol (SNMP) is a protocol used for exchanging management
information between network devices. Your V310 supports SNMP agent functionality, which allows a
manager station to manage and monitor the V310 through the network.
An SNMP managed network consists of two main components: agents and a manager.
An agent is a management software module that resides in a managed device (the V310). An agent
translates the local management information from the managed switch into a form compatible with
SNMP. The manager is the console through which network administrators perform network
management functions. It executes applications that control and monitor managed devices.
The managed devices contain object variables/managed objects that define each piece of
information to be collected about a switch. Examples of variables include number of packets
received, node port status and so on. A Management Information Base (MIB) is a collection of
managed objects. SNMP allows a manager and agents to communicate for the purpose of accessing
these objects.
SNMP itself is a simple request/response protocol based on the manager/agent model. The
manager issues a request and the agent returns responses using the following protocol operations:
Gateway
Enter the IP address of the next-hop gateway. The gateway is a router or switch on the
same segment as your V310's interface(s). The gateway helps forward packets to their
destinations.
Interface
Select an interface through which the traffic is sent.

Allows the manager to retrieve the next object variable from a table or list within an agent.
In SNMPv1, when a manager wants to retrieve all elements of a table from an agent, it
initiates a Get operation, followed by a series of GetNext operations.
Set
Allows the manager to set values for object variables within an agent.
Trap
Used by the agent to inform the manager of some events.
