CHAPTER 3: PORT MANAGEMENT
3.5.2 LACP CONFIGURATION
This page allows the user to inspect the current LACP port configurations, and possibly change them as well.
WEB INTERFACE
To configure the LACP Port Configuration in the web interface:
1. Click Port Management, Link Aggregation and LACP Configuration.
2. Enable or disable the LACP on the port of the switch.
3. Scroll to the Key parameter with Auto or Specific. Default is Auto.
4. Scroll to the Role with Active or Passive. Default is Active.
5. Click Apply to save the setting.
6. To cancel the setting, click the reset button. It will revert to previously saved values.
FIGURE 3-11. LACP CONFIGURATION
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,
10 Mb = 1, 100 Mb = 2, 1 Gb = 3. Using the Specific setting, a user-defined value can be entered. 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. The Active will transmit LACP packets each second, while Passive will wait for a
LACP packet from a partner (speak if spoken to).
Timeout: The Timeout controls the period between BPDU transmissions. Fast will transmit LACP packets each second, while Slow
will wait for 30 seconds before sending a LACP packet.
Prio: The 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. Lower number means greater priority.
