•
Spanning Tree information supporting this role assignment to have reached all
Bridges in the network
AND FOR
•
contradictory information to be received from any Bridge following the change
in Spanning Tree information that first caused this Port to be assigned the Root
Port or Designated Port role.
OR
2.
The Port is now a Root Port AND:
•
any Ports on the Bridge that have been Root Port too recently for Spanning
Tree information to have definitely reached all Bridges in the network
OR
•
any Ports have been contradicted if necessary, are not and will not be put in the
Forwarding Port State until that time has elapsed (with the exception of 3.
below).
OR
3.
The Port is:
•
a Designated Port and attaches to a LAN that has at most one other Bridge
attached
AND
•
the other Bridge’s Port Role assignments are consistent with this port’s Bridge
AND
•
both Port States are known not to be Forwarding if they attach to LANs that
connect to Bridges whose Port Roles are not consistent with that Bridge.
OR
4.
The Port is a Designated Port, attached to a LAN that is known not to be attached to any
other Bridge Ports.
Condition 1 above makes use of Forwarding Delay as the basis for establishing that enough
time has elapsed to allow the transition to the Forwarding state.
