User’s Manual
This page allows the user to inspect the current LACP port configurations, and possibly change them as well. The LACP port
settings relate to the currently selected stack unit, as reflected by the page header. The LACP Configuration screen in Figure
4-5-4 appears.
Figure 4-5-4 : LACP Port Configuration page Screenshot
The page includes the following fields:
Object 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. LACP can
form max 12 LAGs per switch and 2G LAGs per stack.
• 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, 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.
The default setting is “Auto”
• 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.
• Priority
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.
