clear spantree tctrapsuppress
8-24 Spanning Tree Configuration
Usage
By default, RSTP non‐edge (bridge) ports that transition to forwarding or blocking cause the
switch to issue a topology change trap. When topology change trap suppression is enabled, which
is the device default, edge ports (such as end station PCs) are prevented from sending topology
change traps. This is because there is usually no need for network management to monitor edge
port STP transition states, such as when PCs are powered on. When topology change trap
suppression is disabled, all ports, including edge and bridge ports, will transmit topology change
traps.
Example
This example shows how to allow Rapid Spanning Tree edge ports to transmit topology change
traps:
D2(rw)->set spantree tctrapsuppress disable
clear spantree tctrapsuppress
Use this command to clear the status of topology change trap suppression on Rapid Spanning Tree
edge ports to the default state of enabled (edge port topology changes do not generate traps).
Syntax
clear spantree tctrapsuppress
Parameters
None.
Defaults
None.
Mode
Switch command, read‐write.
Example
This example shows how to clear topology change trap suppression setting:
D2(rw)->clear spantree tctrapsuppress
set spantree protomigration
Use this command to reset the protocol state migration machine for one or more Spanning Tree
ports. When operating in RSTP mode, this forces a port to transmit MSTP BPDUs.
Syntax
set spantree protomigration <port-string>
Parameters
port‐string Reset the protocol state migration machine for specific port(s). For a
detailed description of possible port‐string values, refer to “
Port String
Syntax Used in the CLI ” on page 6‐1.
