Bridge configuration
Bridge ID
Displays the bridge ID of the device.
The device with the lowest bridge ID numerical value takes over the role of the root bridge in the
network.
Possible values:

<Bridge priority> / <MAC address>
Value in the
Priority
field / MAC address of the device
Priority
Specifies the bridge priority of the device.
Possible values:

0..61440 in steps of 4096 (default setting: 32768 )
To make this device the root bridge, assign the lowest numeric priority value in the network to the
device.
Hello time [s]
Specifies the time in seconds between the sending of two configuration messages (Hello data
packets).
Possible values:

1..2 (default setting: 2 )
If the device takes over the role of the root bridge, then the other devices in the network use the
value specified here.
Otherwise, the device uses the value specified by the root bridge. See the
Root information

Due to the interaction with the
Tx holds
parameter, we recommend that you do not change the
default setting.
Forward delay [s]
Specifies the delay time for the status change in seconds.
Possible values:

4..30 (default setting: 15 )
If the device takes over the role of the root bridge, then the other devices in the network use the
value specified here.
Otherwise, the device uses the value specified by the root bridge. See the

In the RSTP protocol, the bridges negotiate a status change without a specified delay.
The
Spanning Tree
protocol uses the parameter to delay the status change between the statuses
