Bay Networks 5390 Administering page 549

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 Model 5390 server 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. All generated trap messages use the first
community string defined in the configuration file (if the file does not contain a community string,
the Model 5390 server defaults to public).
You can specify up to ten static trap hosts in the configuration file, but each host requires a separate
line. Specify the trap host using its IP address (RFC 1157 provides more details on communities
and traps).
Table B2-1 describes the supported SNMP traps. The syntax is:
snmp traphost ipaddr
Defining the Contact String
The keyword contact defines the object that identifies the person responsible for managing the
Model 5390 server, as supported by MIB-II. The syntax is:
snmp contact string
The string can include information about how to contact the person; for example, M. Law, x 370.
