Using the BayStack 303 and 304 Ethernet Switches

The Spanning Tree Protocol becomes necessary as networks grow, interconnect with other networks, and generally become more complex. In more complex networks, it is possible to route a message from any given source to any given destination by more than one path. Routing a message over multiple paths can cause several bridges to claim priority in sending the same message. In addition to needless duplication, this situation can result in a loop where messages travel endlessly as each bridge learns the wrong information about where individual nodes are located.

The Spanning Tree Protocol resolves the problem of loops in the network by establishing only one “primary” path between any two LANs in a complex network. Any duplicate paths are barred from use and become standby or blocked paths until the original path fails, at which point they can be brought into service. The Spanning Tree Protocol is enabled by default but can be disabled using a terminal connected to the console port. As your network grows, your BayStack switch continually reinforces the most efficient primary path for messages between any two nodes.

Managing the BayStack Switches

You can manage your BayStack 303 and 304 switches in any of the following three ways:

•In-band signaling using SNMP (see “Network Management with SNMP” on page 3-20)

•Out-of-band signaling using the RS-232 console port interface (see “Network Management through a Serial I/O Connection” on page 3-22)

•In-band signaling using Telnet (see “Network Management Using a Telnet Connection” on page 3-22)

Network Management with SNMP

The BayStack 303 and 304 Ethernet Switches use the Simple Network Management Protocol (SNMP), a communications protocol that simplifies the management of network devices. SNMP agents respond to queries sent by network management software. Responses to these queries are presented on a network management station. These agents collect the performance and activity
