WebView Switches

Path Cost Default Values

Specifies the method used to

assign default path costs to STP ports. The possible field
values are:

Short

Specifies a 1–65,535 range for port path costs.

This is the default value.

Long

Specifies a 1–200,000,000 range 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 1–10 seconds.

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 6–40 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 4–30 seconds.

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 30–60 seconds
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.
