ABOUT THE TIGERSWITCH 100

Spanning Tree Protocol

The TigerSwitch 100 switches support the ANSI/IEEE 802.1d Spanning Tree Protocol. This protocol adds a level of fault tolerance by allowing two or more redundant connections to be created between a pair of LAN segments. When there are multiple physical paths between segments, the protocol will choose a single path and disable all others to ensure that only one route exists between any two stations on the network. This prevents the creation of network loops. However, if the chosen path should fail for any reason, an alternate path will be activated to maintain the connection.

The default setting for Spanning Tree Protocol is “enabled”. This protocol may be configured (enabled or disabled) out-of-band via the serial console port or in-band via the SNMP agent or Telnet.
