Moxa IKS-6728A-4GTXSFP-24-24-T [26/37] Explanation of status items

Managed Ethernet Switch Redundancy Protocol (UI 2.0) STP/RSTP/MSTP

5-7

The following figure indicates which Spanning Tree Protocol parameters can be configured. A more detailed

explanation of each parameter follows.

Explanation of “Status” Items

Active Protocol

Shows which redundancy protocol is in use: Turbo Ring, Turbo Ring V2, Turbo Chain, RSTP, MSTP, or

None.

Role

This field only appears when RSTP mode is selected. The field indicates whether or not this switch is the Root

of the Spanning Tree (the root is determined automatically).

Explanation of “Settings” Items

Forwarding delay (sec.)

Setting Description Factory Default

Numerical value input

by user

The amount of time this device waits before checking to see if it

should change to a different state.

Bridge priority

Setting Description Factory Default

Numerical value

selected by user

Increase this device’s bridge priority by selecting a lower

number. A device with a higher bridge priority has a greater

chance of being established as the root of the Spanning Tree

topology.

32768

Hello time (sec.)

Setting Description Factory Default

Numerical value input

by user

The root of the Spanning Tree topology periodically sends out a

“hello” message to other devices on the network to check if the

topology is healthy. The “hello time” is the amount of time the

root waits between sending hello messages.
