The following global attributes can be configured:
• Spanning Tree State – Enable/disabled this switch to participate
in a STA-compliant network.
• Priority – Bridge priority is used in selecting the root device, root
port, and designated port. The device with the highest priority
becomes the STA root device. However, if all devices have the same
priority, the device with the lowest MAC address will then become the
root device. (CLI only)
- Default: 32768
- Range: 0 - 65535
• Hello Time – Interval (in seconds) at which the root device transmits
a configuration message.
- Default: 2
- Minimum: 1
- Maximum: The lower of 10 or [(Max. Message Age / 2) -1]
• Maximum Age – The maximum time (in seconds) a device can wait
without receiving a configuration message before attempting to
reconfigure. All device ports (except for designated ports) should
receive configuration messages at regular intervals. Any port that ages
out STA information (provided in the last configuration message)
becomes the designated port for the attached LAN. If it is a root port,
a new root port is selected from among the device ports attached to the
network. (References to “ports” in this section means “interfaces,”
which includes both ports and trunks.)
- Default: 20
- Minimum: The higher of 6 or [2 x (Hello Time + 1)].
- Maximum: The lower of 40 or [2 x (Forward Delay - 1)]
