Model 5399 Remote Access Concentrator Network Administrator’s Guide for UNIX
Chapter 2 Simple Network Management Protocol (SNMP)
A-60
Book A
Traps are unsolicited administrative messages generated by SNMP agents
on the network. The keyword traphost defines the host to which SNMP
traps are sent. For the 5399 RAC to generate traps, one or more trap host
addresses must be defined in the gateway section of the configuration
file along with the SNMP community string. You can also temporarily
add or modify the trap host definitions All generated trap messages use
the first community string defined in the configuration file (if the file
does not contain a community string, the 5399 RAC defaults to public).
You can specify up to ten static trap hosts in the configuration file, but
each host requires a separate line. Specify a trap host using its IP address
(RFC 1157 provides more details on communities and traps). Table B-16
describes the standard SNMP traps supported by the 5399 RAC. The
proprietary traps and description are in the Alarms Traps section. The
syntax is:
snmp traphost ipaddr
Table B-16. Supported SNMP Traps
Defining the Contact String
The keyword contact defines the object that identifies the person
responsible for managing the 5399 RAC, as supported by MIB-II. The
syntax is:
snmp contact string
The string can include information about how to contact the person, e.g.,
M. Law, x 370 (MIB-II object contact).
