SunScreen 3.1 Administration Guide

SNMP Alert Receivers

You set actions that generate SNMP alerts as part of a security policy.

You use the SNMP tab in the Screen dialog window to:

A management information base (MIB) that describes the SNMP trap is included with the SunScreen CD-ROM, as part of the SUNWicgSA package. It is installed as: /opt/SUNWicg/SunScreenAdmin/etc/sunscreen.mib. Load this MIB into your SNMP manager to enable it to use the SNMP trap generated by the Screen.

Note -

The machine that you want to receive SNMP trap alerts must not be a remote Administration Station. SNMP alert packets are sent in the clear and the communication between the remote Administration Station and Screen is encrypted; any packets sent in the clear are dropped.

The recipients of SNMP messages are controlled on a Screen-by-Screen basis. The Screen object has a place for an optional list of IP addresses, which are the hosts to which it sends the SNMP packets.

Setting SNMP in a packet filtering rule's "Action," or in the default Reject Action of an interface causes the SNMP packets to be sent.

SNMP alerts are described in the SunScreen Reference Manual.

The following information describes using the administration GUI. For the command line interface, see Appendix A.
