2-6.2 LACP
This page lets you view and change the current LACP port configuration parameters. An LACP trunk group
with more than one ready member-ports is a “real trunked” group. An LACP trunk group with one or less
ready member-ports is not a “real trunked” group.
Note
: LACP and Static aggregation cannot both be
enabled on the same ports.
To configure LACP port parameters in the web UI:
1. Click Configuration, Aggregation, LACP.
2. Enable or disable LACP on the switch ports.
3. Select the Key parameter (Auto or Specific). The default is Auto.
3. Select the Role (Active or Passive). The default is Active.
4. Click the Apply button to save the settings.
5. To cancel the settings, click the Reset button to revert to previously saved values.
Figure 2-5.2: LACP Port Configuration page
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, in the 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.
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:
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:
Sets 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.
