The Spanning Tree Algorithm (STA) can be used to detect and disable
network loops, and to provide backup links between switches, bridges or
routers. This allows the switch to interact with other bridging devices (that
is, an STA-compliant switch, bridge or router) in your network to ensure
that only one route exists between any two stations on the network, and
provide backup links which automatically take over when a primary link
goes down.
Enables BPDU loopback SNMP trap notification for a
port
IC
Configures the path cost of an instance in the MST
IC
Configures the priority of an instance in the MST
IC
Floods BPDUs to other ports when global spanning tree
is disabled
IC
Configures the spanning tree priority of an interface
IC
Prevents a designated port from passing superior
BPDUs
IC
Disables spanning tree for an interface
IC
Stops propagating topology changes on an interface
IC
Manually releases a port placed in discarding state by
loopback-detection
PE
Re-checks the appropriate BPDU format
PE
Shows spanning tree configuration for the common
spanning tree (i.e., overall bridge), a selected
interface, or an instance within the multiple spanning
tree
PE
Shows the multiple spanning tree configuration
