Managing SNMP

8-18 Express5800/ftServer: System Administrator’s Guide for the Linux Operating System

Verifying Traps

You can easily verify traps using snmptrapd on a remote Linux system with

Net-SNMP installed.

1. On the remote Linux system, set up Net-SNMP to autostart, and verify it using the

chkconfig command, or manually start Net-SNMP.

2. On the ftServer system with the Linux operating system, Express Builder, Net-SNMP,

and ftlSNMP installed, configure /etc/opt/ft/snmp/snmpd.conf with trapsink

entries that point to the IP address of a remote management system running

snmptrapd, by adding lines as follows:

trapcommunity

public

trapsink

ip_address

public

trap2sink

ip_address

public

In this example, ip_address is the IP address of the remote management

system.

3. Start (or restart) SNMP using the /etc/opt/ft/snmp/scripts/start_snmp

(or /etc/opt/ft/snmp/scripts/restart_snmp) command for changes to

take effect.

4. From the remote management system, you can view the traps as they are

generated, by tailing /var/log/messages (or wherever the remote management

system is configured to log snmptrapd messages):

tail -f /var/log/messages

Pulling CPU-I/O enclosures and/or pulling Ethernet cables on the ftServer system will

generate traps, as will exercising the system using the ftsmaint command.
