Configuring the SSR for SNMP
The Simple Network Management Protocol (SNMP) provides support for monitoring and
controlling network devices, collecting statistics, and managing configurations,
performance, and security. SNMP is mainly used by TCP/IP networks.
You configure the SSR for SNMP by performing the following tasks:
• Setting up targets for SNMP traps. A target is a management station to which the SSR
sends SNMP traps, which are messages that describe an event (such as restarting the
SSR or a link going down).
• Establishing community strings that SNMP management stations must supply to
access the SSR.
Separate discussions on these SNMP tasks follow.
Setting Up a Target for SNMP Traps
Set up a target for SNMP traps to specify to which server you want the SSR to send SNMP
traps. To set up an SNMP trap target on the SSR:
1. Make sure there is a network connection to the server to which you want the SSR to
send SNMP traps. You can do so by sending a ping packet to the desired server.
2. Start Configuration Expert if you have not already done so.
3. Open the configuration file you want to modify and then double-click that file’s
System Configuration object.
4. Double-click the SNMP Configuration object.
5. Configuration Expert displays the SNMP Trap Target and SNMP Community String
objects.
