Scenario 2 — Forwarding Alerts in the Original Format Using SNMP v2/v2c Protocol

In this scenario, SNMP v2 alerts are sent from MNv2 to MS1 and then forwarded from MS1 to MS3. If you try to retrieve

the remote host of the forwarded alert from MS3, it is displayed as MS1

Since there are no fields in an SNMP v2 alert to specify the agent name, the host which sends the alert is assumed as

the agent. When an SNMP v2 alert is forwarded from MS1 to MS3, MS1 is considered as the source of problem. To

resolve this issue, while forwarding SNMP v2 or v2c alerts, a varbind is added with OID as .1.3.6.1.6.3.18.1.3.0 with the

variable value as Agent Address. This has been set based on the standard OID specified in RFC2576-MIB. When you try

to retrieve the Agent Address from MS3, it is displayed as MNv2

NOTE: If the SNMP v2 alert is forwarded from MS1 to MS2, the remote host is displayed as MNv2 because MS1

parses the extra OID along with the forwarded trap.

Scenario 3 — Forwarding Alerts in the OMEssentials Format Using Either SNMP v1/v2 Protocol

In this scenario, SNMP v1 alerts are sent from MNv1 to MS1 and then forwarded to MS2. If you try to retrieve the remote

host of the forwarded alert, it is displayed as MS1. The severity and the message of the alert is also defined by MS1 and

does not display the original severity and message defined by MNv1.

NOTE: The same behavior applies for SNMPv2 traps.
