Note these additional items:

■The linkState up or down applies to Ethernet and Fast Ethernet ports, not 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.

*The Port State is either blocking or forwarding. The final state depends on the Spanning Tree configuration of the network.
