hi every body!A
A switch is connected to another switch by 802.1q trunk.
Does switch send only bpdu belonging to stp instance, native vlan mapped to?
thanks a lot!
Which makes a lot of sense because 3rd party switches do not support PVST so they have a CST (Common Spanning Tree).
Thanks for the info Sarah - rated.
The switch sends bpdus for each vlan that is configured and not pruned from the trunk with the "switchport trunk allowed vlan" command.
