You are now ready to communicate with the Switch 2000 TR using IP and an SNMP-based management application. Refer to Chapter 5 for more information on conﬁguring the bridge, port, and other manage- ment tasks.

Setting Up BOOTP

The BOOTP option allows you to enable or disable the bootstrap protocol. The BOOTP (bootstrap protocol) allows the switch to discover and learn its own IP address and routing table information. To conﬁgure a Switch 2000 TR with the BOOTP option you will need a BOOTP server program. The MAC address, recorded on a label on the rear panel of the Switch 2000 TR, must be entered in the BOOTP server program along with the corresponding IP address of the Switch 2000 TR and its default route information. This allows the BOOTP request from the agent to be logged by the BOOTP server which then supplies the required IP information.

Table 3-3
