Note: The parameters
Forward delay [s]
and
Max age
have the following relationship:
Forward delay [s]
≥ (
Max age
/2) + 1
If you enter values in the fields that contradict this relationship, then the device replaces these
values with the last valid values or with the default value.
Note: When possible, do not change the value in the “Hello Time” field.
Check the following values in the other devices:
– Bridge ID (bridge priority and MAC address) of the corresponding device and the root bridge.
– Number of the device port that leads to the root bridge.
– Path cost from the root port of the device to the root bridge.
spanning-tree forward-time <4..30>
Specifies the delay time for the status change in
seconds.
spanning-tree max-age <6..40>
Specifies the maximum permissible branch length,
for example the number of devices to the root
bridge.
