Advanced Configuration

Path Cost Default Values  Specifies the method used to assign default path costs to STP ports. The possible field values are:

•• Short  Specifies a 1–65,535range for port path costs. This is the default value.

•• Long  Specifies a 1–200,000,000range 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 32,768. The port priority value is provided in increments of 4096. For example, 4096, 8192, 12,288, and so on. The range is 0–65,535.

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 2 seconds. The range is 1–10seconds.

Max Age  Specifies the device Maximum Age Time. The Maximum Age Time indicates the amount of time in seconds a bridge waits before sending configuration messages. The default max age is 20 seconds. The range is 6–40seconds.

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 4–30seconds.

Spanning Tree > STP Port Settings

Network administrators can assign STP settings to specific interfaces using the STP Interface Settings screen.

Spanning Tree > STP Port Settings

The STP Interface Settings page contains the following fields:

Interface  Indicates the port or LAG on which STP is enabled.

STP  Indicates if STP is enabled on the port.

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 30–60seconds in large networks.

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  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 Classic STP is enabled.

•• Listening  Indicates that the port is in Listening mode. The port cannot forward traffic nor can it learn MAC addresses.

•• Learning  Indicates that the port is in Learning mode. The port cannot forward traffic, however it can learn new MAC addresses.

•• Forwarding  Indicates that the port is in Forwarding mode. The port can forward traffic and learn new MAC addresses.

Speed  Indicates the speed at which the port is operating.
