With this enhancement:
•STP and Port Trunking now work together correctly.
•BDPU Forwarding is implemented. The BPDU Forwarding feature configures the switch to forward all received STP BPDUs. Under normal circumstances, the switch will not forward any received STP BPDUs, even if STP is enabled.
This implementation is for standard STP, it does not guarantee that RSTP and port trunking will work correctly together in all situations.
STP does not update the pathcost for trunked ports, which means that a trunk group has the same pathcost as a single port. This may cause STP Blocking where it is not expected. To overcome this, the user should explicitly set the pathcost for the trunk group ports to be less than the default value for a single port.
STP reconfigures if the Master port in a trunk group goes link down. If the Master port in a trunk group goes link down, and a
Command handler changes:
•The PORT parameter of the CREATE SWITCH TRUNK PORT and ADD SWITCH TRUNK PORT commands must specify ports that have identical STP port configurations.
•The ENABLE STP and ENABLE STP PORT commands cannot be used to enable STP operation on a port that has been disabled from STP operation because of Port Trunking. Only the Master port in a trunk group actively participates in the STP algorithm.
•The output for the SHOW STP PORT command has been modifed so that
•The output for the SHOW STP PORT command has been modified so that it displays whether a user has set the PATHCOST value, or if it was
