Note these additional items:
■ The linkState up or down settings apply to Ethernet and Fast Ethernet
ports, not to FDDI ports, and only when the stpState for the bridge is
enabled. If the stpState on the Bridge menu is disabled, the State for the
port remains in forwarding state.
■ When the bridge port is in the Removed state, the State remains in
forwarding state.
■ If STP is disabled on an individual port, the State remains disabled.
Table 1 describes the port states and how they relate to the linkState. This
table is valid only when the stpState for the bridge is enabled.
