ABOUT THE SWITCHES

Spanning Tree Protocol

The TigerSwitch 16 family supports the 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 can choose a

single path at any given time and disable all others. This

prevents network traffic from circulating in an endless loop.

However, if the chosen path fails for any reason, an alternate

path will be activated to maintain the connection.

The default factory setting for Spanning Tree Protocol is

“enabled.” This protocol can be configured (enabled and dis-

abled) out-of-band via the serial console interface or in-band via

SNMP or Telnet.
