Note trapsink is used in SNMP version 1; trap2sink is used in SNMP version 2.

trapcommunity defines the default community string to be used when sending traps. This command must appear prior to trapsink or trap2sink which use this community string.

trapsink and trap2sink are defined as follows:

trapsink hostname community port trap2sink hostname community port

System Contact Information

System contact information is provided in two variables through the snmpd.conf file, syslocation and syscontact.

Look for the following lines in the snmpd.conf file:

###############################################################################

#System contact information

syslocation Your Location, A Building, 8th Floor syscontact A. Person <someone@somewhere.org>
