NETGEAR FS728TS User Manual page 75

•
Hello Time (1-10) — Specifies the device Hello Time. The Hello Time indicates the amount of time in seconds a Root The device waits
between configuration messages. The default is 2 seconds.
•
Max Age (6-40) — Specifies the device Maximum Age Time. The Maximum Age Time is the amount of time in seconds a bridge waits before
sending configuration messages. The default Maximum Age Time is 20 seconds.
•
Forward Delay (4-30) — Specifies the device Forward Delay Time. The Forward Delay Time is the amount of time in seconds a bridge
remains in a listening and learning state before forwarding packets. The default is 15 seconds.
•
Unit Number — Indicates the stacking member for which the STP information is displayed.
•
Interface — Indicates the port or LAG for which the STP information is displayed.
•
Fast Link — 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 field values are:
Enable — Indicates that Fast Link is enabled on the port.
–
Disable — Indicates that Fast Link is disabled on the port.
–
•
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:
Forwarding — Indicates that STP is enabled on the port, and the port is forwarding packets based on the STP topology.
–
Disabled — Indicates that STP is currently disabled on the port. The port forwards traffic while learning MAC addresses.
–
Blocking — Indicates that the port is currently blocked and cannot forward traffic or learn MAC addresses. Blocking is displayed when
–
STP is enabled.
•
Speed — Indicates the speed at which the port is operating.
•
Path Cost — Specifies the method used to assign default path cost to STP ports. The possible field values are:
Short — Specifies 1 through 65,535 range for port path cost. This is the default value.
–
Long — Specifies 1 through 200,000,000 range for port path cost. The default path cost assigned to an interface varies according to the
–
selected method (Hello Time, Max Age, or Forward Delay).
•
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 32768. The port priority value is provided in
increments of 4096.
•
BPDU Handling — Determines how BPDU packets are managed when STP is disabled on the port or device. BPDUs are used to transmit
spanning tree information. The possible field values are:
Filtering — Filters BPDU packets when spanning tree is disabled on an interface. This is the default value.
–
Flooding — Floods BPDU packets when spanning tree is disabled on an interface.
–
•
Priority (0-65535) — Reflects the value entered in the Priority field above.
2. Select Enable in the Spanning Tree State field.
3. Select an STP type in the STP Operation Mode field.
4. Define the BPDU Handling and Path Cost Default Values fields.
5. Select either the Hello Time, Max Age, or Forward Delay field.
6. Click . STP is enabled and the device is updated.
