Configuration Using the Web-based Utility
8
Business Series Smart Gigabit Ethernet Switch
Long
Specifies a range of 1-200,000,000 for port path
costs. The default path costs assigned to an interface
varies according to the selected method.
Bridge Settings
Priority
Specifies the bridge priority value. When
switches or bridges are running STP, each is assigned a
priority. After exchanging BPDUs, the device with the
lowest priority value becomes the Root Bridge. The default
value is
768
. The value must be a multiple of 4096. For
example, 4096, 8192, 12288, etc. The range is
0
to
6
.
Hello Time
Specifies the device Hello Time. The Hello
Time indicates the amount of time in seconds a root bridge
waits between configuration messages. The default is
seconds. The range is
to
0
seconds.
Max Age
Specifies the device Maximum Age Time. The
Maximum Age Time is the amount of time in seconds that
a bridge waits before sending configuration messages.
The default is
0
seconds. The range is
6
to
40
seconds.
Forward Delay
Specifies the device forward delay time.
The Forward Delay Time indicates the amount of time in
seconds a bridge remains in a listening and learning state
before forwarding packets. The default is 15 seconds. The
range is
4
to
0
seconds.

Spanning Tree > STP Port Settings
The
STP Port Settings
screen allows network administrators
to assign STP settings to specific interfaces.
Spanning Tree > STP Port Settings
Interface
Indicates the port or LAG on which STP is
enabled. Select either
Port
(default) or
LAG
, then select
the interface from the drop-down menu.
Enable STP
Select this to enable STP on the port. The
default is Enabled.
Port Fast
Indicates if Fast Link is enabled on the port.
If Fast Link mode is enabled for a port, the Port State
is automatically placed in the Forwarding state when
the port link is up. Fast Link optimizes the STP protocol
convergence. STP convergence can take 30-60 seconds in
large networks. The possible values are
Enable
,
Auto
, and
Disable
. The default is
Disable
.
Port State
Displays the current STP state of a port. If
enabled, the port state determines what forwarding
action is taken on traffic. Possible port states are:
Disabled
STP is currently disabled on the port. The
port forwards traffic while learning MAC addresses.
Blocking
The port is currently blocked and cannot
forward traffic or learn MAC addresses.
Listening
The port is in Listening mode. The port
cannot forward traffic nor can it learn MAC addresses.
Learning
The port is in Learning mode. The port
cannot forward traffic, but can learn new MAC
addresses.
Forwarding
The port is in Forwarding mode. The port
can forward traffic and learn new MAC addresses.
Speed
Displays the speed at which the port is operating.
Path Cost
Indicates the port contribution to the root path
cost. The path cost is adjusted to a higher or lower value,
and is used to forward traffic when a path being rerouted.
The default value is
000000
for a 10M port,
00000
for a
100M port, and
0000
for a 1G port or a LAG.
Default Path Cost
When selected the default path cost is
implemented. The default is unselected.
Priority
Priority value of the port. This value influences
the port choice when a bridge has two ports connected in
a loop. The range of values is
0
-
40
. The default is
8
.
Designated Bridge ID
Displays the bridge priority and
the MAC Address of the designated bridge.
Designated Port ID
Displays the selected port’s priority
and interface.
Designated Cost
Displays the cost of the port
participating in the STP topology. Ports with a lower cost
are less likely to be blocked if STP detects loops.
Forward Transitions
Displays the number of times the
port has changed from the Blocking state to Forwarding
state.
