Appendix E: Setting SNMP Traps (Windows NT/

2000/XP Only)

An SNMP (Simple Network Management Protocol) trap is a notification sent by a

DS appliance to a host system indicating that an event has occurred in the DS

appliance that may require further attention.

SNMP is a protocol used to communicate management information between

network management applications and DS appliances using TCP/IP and IPX pro-

tocols. Other SNMP managers (such as Tivoli and HP OpenView) may communi-

cate with your DS appliance by accessing MIB-II (Management Information Base)

and the public portion of the enterprise MIB. MIB-II is a standard MIB that many

SNMP target devices support. When you access a DS appliance for the first time,

DSAuth will retrieve the SNMP parameters from the DS appliance.

DS appliances are defined on the host by criteria such as system information,

which stations may manage the DS appliance, which stations may receive

SNMP traps from the switch and the community to which they belong. If you

select Options - System Settings from the DSAuth window and then check Enable

SNMP trap log in the System Settings dialog box, the appliance will log SNMP

received messages over UDP (User Datagram Protocol) port 162.

The traps must be configured on each DS appliance using the CLI interface.

The address of the server running DSAuth must be configured as a trap recipi-

ent, the proper community must be set, and each desired trap must be enabled.

To use SNMP trap logging:

1. Install and conﬁ gure TCP/IP on the DSAuth Server.

2. Install the SNMP service on the DSAuth Server, conﬁ gure the host as trap

recipient and enable the traps.

3. Enable the SNMP service on the DSAuth Server.
