ARAMETERS
These parameters are displayed in the web interface:
◆
Interface
– Displays a list of ports or trunks.
◆
Spanning Tree
– Enables/disables STA on this interface.
(Default: Enabled)
◆
BPDU Flooding
- Enables/disables the flooding of BPDUs to other
ports when global spanning tree is disabled (
) or when
spanning tree is disabled on specific port. When flooding is enabled,
BPDUs are flooded to all other ports on the switch or to all other ports
within the receiving port’s native VLAN as specified by the Spanning
Tree BPDU Flooding
attribute (
).
◆
Priority
– Defines the priority used for this port in the Spanning Tree
Protocol. If the path cost for all ports on a switch are the same, the port
with the highest priority (i.e., lowest value) will be configured as an
active link in the Spanning Tree. This makes a port with higher priority
less likely to be blocked if the Spanning Tree Protocol is detecting
network loops. Where more than one port is assigned the highest
priority, the port with lowest numeric identifier will be enabled.

Default: 128
■
Range: 0-240, in steps of 16
◆
Admin Path Cost
– This parameter is used by the STA to determine
the best path between devices. Therefore, lower values should be
assigned to ports attached to faster media, and higher values assigned
to ports with slower media. Also, not that path cost takes precedence
over port priority. (Range: 0 for auto-configuration, 1-65535 for the
short path cost method
4
, 1-200,000,000 for the long path cost method)
By default, the system automatically detects the speed and duplex
mode used on each port, and configures the path cost according to the
values shown below. Path cost “0” is used to indicate auto-configuration
mode. When the short path cost method is selected and the default
path cost recommended by the IEEE 8021w standard exceeds 65,535,
the default is set to 65,535.
4. Refer to
"Configuring Global Settings for STA" on page 209
for information on setting
the path cost method.
