Parameter description:
 Port: The switch port number.
 LACP Enabled: Controls whether LACP is enabled on this switch port. LACP will form an aggregation when 2 or more ports are
connected to the same partner.
 Key: The Key value incurred by the port; range 1–65535 . The Auto setting will set the key as appropriate by the physical link speed,
10Mb = 1, 100Mb = 2, 1Gb = 3. Using the Specific setting, you can enter a user-defined value. Ports with the same Key value can
participate in the same aggregation group, while ports with different keys cannot.
 Role: The Role shows the LACP activity status. Active will transmit LACP packets each second, while Passive will wait for a LACP
packet from a partner (speak if spoken to).
 Timeout: Timeout controls the period between BPDU transmissions. Fast will transmit LACP packets each second, while Slow will
wait for 30 seconds before sending an LACP packet.
 Prio: Prio controls the priority of the port. If the LACP partner wants to form a larger group than is supported by this device, then this
parameter will control which ports will be active and which ports will be in a backup role. A lower number means greater priority.
 Buttons:
- Apply – Click to save changes.
- Reset – Click to undo any changes made locally and revert to previously saved values.

on “Resume” to turn on the locked port.
