Snmp Versions - Avaya G250 Administration

Configuring SNMP
Retrieve a number of values — a get-bulk action.
●
The get-bulk operation retrieves the specified number of instances of the requested MIB
variable. This minimizes the number of protocol exchanges required to retrieve a large
amount of data.
Note:
Get-bulk is not supported in SNMPv1.
Note:
Change a configuration on the agent — a set action.
●
The SNMP manager requests the agent to change the value of the MIB variable. For
example, you can run a script or an application on a remote device with a set action.
An agent can send an unsolicited message to the manager at any time if a significant,
●
predetermined event takes place on the agent. This message is called a notification.
When a notification condition occurs, the SNMP agent sends an SNMP notification to the
device specified as the trap receiver or trap host. The SNMP Administrator configures the
trap host, usually the SNMP management station, to perform the action needed when a
trap is detected.

SNMP versions

There are currently three versions of SNMP:
SNMPv1
●
SNMPv2c
●
SNMPv3
●
The Avaya G350 Media Gateway supports all three of these versions. The implementation of
SNMPv3 on the Avaya G350 Media Gateway is backwards compatible. An agent that supports
SNMPv3 will also support SNMPv1 and SNMPv2c.
The Avaya G250 Media Gateway supports users for all three of these versions, but only
supports the SNMPv3 mechanism for sending traps. Thus, the set snmp trap command is not
supported in the G250, although the set snmp trap enable auth|frame-relay
command is supported.
