NOTE
A BPDU (Bridge Protocol Data Unit) transmission is an STP information-exchange packet
sent out at periodic intervals to other units in the network, to detect loops in the network
topology.

MN700004 Rev 01
Spanning Tree Protocol (STP)
D e s c r i p t i o n
Displays the current STP parameter settings.
Enables/disables the STP option.
Sets the STP bridge priority
Sets time interval between BPDU transmissions from the ports of
this unit
Sets the time duration in Listening and Learning states that
precede the Forwarding state. Also used to age dynamic entries in
the Forwarding database when a topology change is under way.
Sets the time that learned STP information is kept before being
discarded.
Changes to specified interface configuration mode and displays the
STP settings for that interface.
Reconfigures the STP or RSTPto use the alternate (backup) link in
case of CRC errors.
D e s c r i p t i o n
Displays all STP ports table
Sets STP port path-cost
Sets STP port priority
Sets the STP parameters to their default values for the configured
interface.
Enables Topology change detection.
