Cingular GPRS Raven User Guide Version 2.01 45
Simple Network Management Protocol (SNMP)
Management Information Base (MIB)
The management information base (MIB) is a type of database used to compile the
information from the various SNMP agents. Reports from various agents, such as
the Raven, are sent as data in form designed to be parsed by the NMS into its MIB.
The data is hierarchical with entries addressed through object identifiers.
SNMP Traps
The trap is a “snap-shot” of the settings and status of the Agent’s device which is
sent as a report to the NMS in a form that can be parsed and stored in the MIB. See
below (page 48) for an example of the trap from an AirLink modem.
Raven SNMP Configuration
To configure your Raven to work as an SNMP agent, you can use either Wireless
ACE (page 15), direct serial communication or Telnet (page 76page 58) to config-
ure the modem using AT commands (page 79page 61). In Wireless ACE, the
SNMP commands are all on the Other menu option.
There are only three commands to set for SNMP in the Raven: the listening port,
the security level, and the trap destination.
Listening Port
*SNMPPORT sets the port for the SNMP agent to listen on. If set to zero, default,
SNMP is disabled.
FIGURE 1. Wireless ACE: *SNMPPORT
SNMP generally uses port 161, however most Internet providers
(including cellular) block all ports below 1024 as a security measure.
You should be able to use higher numbered port such as 10161.
