Limitations

• Dynamic LACP, static trunks, and distributed trunks will not support this feature.
• The command is not available for REST/next Gen UI.
• If the LACP trunk is down due to lack of active links with the timer enabled, a dynamic update to the enable-
timer by configuration will not take effect immediately as the current timer runs with the previously configured
value.
• When the LACP trunk is blocked by min-active-links and the enable-timer is running, the member
links will be prevented from becoming operational even if there is an external intervention caused by
configuration or topology changes.
• If the enable-timer is not configured, the operator must restore the member links of the LACP trunk which
are blocked by the minimum active links.
• If there is a flap in any member links, the LACP trunk disabled by min-active-links may end up flapping
when enable-timer is not configured.
• The min-active-links feature is not supported on the previous releases (that is prior to 16.08 version). On
downgrading the switch to the previous version, the configuration will be removed without any warning.

Viewing existing port trunk groups (WebAgent)

While the WebAgent does not enable you to configure a port trunk group, it does provide a view of an existing
trunk group.
To view any port trunk groups:
1. In the navigation pane, click Interface.
2. Click Port Info/Config. The trunk information for the port displays in the Port Properties box.

Trunk group operation using LACP

The switch can automatically configure a dynamic LACP trunk group, or you can manually configure a static
LACP trunk group.
NOTE: LACP requires full-duplex (FDx) links of the same media type (10/100Base-T, 100FX, and so
on) and the same speed and enforces speed and duplex conformance across a trunk group. For
most installations, it is recommended that you leave the port mode settings at Auto (the default).
LACP also operates with Auto-10, Auto-100, and Auto-1000 (if negotiation selects FDx), and
10FDx, 100FDx, and 1000FDx settings.
LACP trunk status commands include:
Trunk display method
CLI show lacp command
CLI show trunk command
Thus, to display a listing of dynamic LACP trunk ports, you must use the show lacp command.
