CANOGA PERKINS 9135G SNMP Managed Gigabit Ethernet Switch - Manual (Page 30)

EdgeAccess Ethernet Switch
When Spanning Tree is enabled, the 9135G monitors the incoming data packets while sending out
Bridge PDUs (Protocol Data Unit) at a user designated time interval. The Spanning Tree monitors the
incoming data packet addresses and checks them against the forwarding database (Fdb) table. If it
sees the same Bridge PDU arriving on two ports, it will disable one port to remove the loop.
Note: For details on the Spanning Tree Algorithm if you plan to use STP (Spanning Tree Protocol),
review the IEEE 802.1 specifications.
