10.3. Forwarding SNMP traps

It is possible to forward SNMP traps to a machine that is not part of the cluster where you can use the snmptrapd daemon on the external machine and customize how to respond to the notifications.

Perform the following steps to forward SNMP traps in a cluster to a machine that is not one of the cluster nodes:

For each node in the cluster, follow the procedure described in Section 10.2, “Configuring SNMP with the Red Hat High Availability Add-On”, setting the trap2sink host entry in the /etc/snmp/snmpd.conf file to specify the external host that will be running the snmptrapd daemon.
On the external host that will receive the traps, edit the /etc/snmp/snmptrapd.conf configuration file to specify your community strings. For example, you can use the following entry to allow the snmptrapd daemon to process notifications using the public community string.
```
authCommunity log,execute,net public
```
On the external host that will receive the traps, make sure that the snmptrapd daemon is enabled and running by executing the following commands:
```
# chkconfig snmptrapd on
# service snmptrapd start
```

For further information on processing SNMP notifications, see the snmptrapd.conf man page.
