Chapter 3: Software Description
• Key Value: Configures a port's LACP administration key. The port administrative
key must be set to the same value for ports that belong to the same link
aggregation group (LAG). If this administrative key is not set when an LAG is
formed (i.e., it has the null value of 0), this key will automatically be set to the
same value as that used by the LAG.

3.2.6 RSTP
IEEE 802.1w Rapid Spanning tree protocol (LACP) provides a loop-free network
and redundant links to the core network with rapid convergence to ensure faster
recovery from failed links, enhancing overall network stability and reliability.
3.2.6.1 RSTP System Configuration
• System Priority: This parameter configures the spanning tree priority globally for
this switch. The device with the highest priority becomes the STP root device.
However, if all devices have the same priority, the device with the lowest MAC
address will then become the root device.
• Hello Time: Interval (in seconds) at which the root device transmits a
configuration message (BPDU frame). Number between 1–10 (default is 2).
• Max Age: The maximum time (in seconds) a device can wait without receiving a
configuration message before attempting to reconfigure. This also means the
maximum life time for a BPDU frame. Number between 6–40 (default is 20).
