VBRIDGE/CONFIG/BRIDGE/PARAPORT Parameters
Parameter Description
Port Priority Part of port ID which is used to determine which port gets blocked or
forwarded
Range: 0 to 25
Default setting: 128
Path Cost The contribution of the path through this port, when the port is the root port,
to the total cost of the path to the root for this bridge. The smaller the number,
the smaller the cost. The Spanning Tree Protocol allocates a cost of 100 to 10
Mbps ports and 10 to 100 Mbps ports, and ensures that an active topology
generates the minimal path costs (IEEE 802.1D).
Manual Mode The hardware status for the port:
(f) hardware forwarding state, Spanning Tree off
(b) hardware blocking state, Spanning Tree off
(s) Spanning Tree is enabled. However, if Spanning Tree is disabled for the
VLAN, this mode defaults to forwarding state. If Spanning Tree is enabled for
the VLAN, this setting defaults to (s).
This setting also interacts with the Spanning Tree Enabled setting in this
menu in the following ways:
Sp Tree Enabled Manual Mode Port State
y s Spanning Tree state
n s HW blocking
y f HW forwarding
n f HW forwarding
y b HW blocking
n b HW blocking
Spanning Tree Enabled Enables or disables Spanning Tree. (See Manual Mode above.)
