Field
Mode
Port Members
Traffic across a trunk is distributed among trunk members. All ports in a trunk have the same full
duplex speed.
Loop protection is not supported on LACP trunks. Loop protection will be auto-disabled if it was
previously enabled on a static trunk that is now being configured as LACP Active or Passive.
RSTP can be enabled on a trunk. When RSTP is either enabled or disabled on a trunk, the individual
Port members lose their STP configuration and will take on the trunk's configuration. When ports
are removed from a trunk, the port members return to their earlier configured STP states.
An active port (LACP and Static active members) added to a trunk loses port VLAN membership
and is assigned to that trunk group's VLAN membership. When the port is removed from a trunk
it reverts to the default VLAN.

Trunk Modes

A trunk can be configured in four different modes: Disabled, Static, LACP Active, and LACP Passive.
After configuring trunk modes, click Apply to save changes to the selected trunk. Changes take
effect immediately.

Disabled Trunk Mode

When a trunk is disabled, no traffic flows and LACPDUs are dropped. The links that form the trunk
are not released.

Description
Mode (static or dynamic) configured for the trunk.
Select the trunk membership for a port. By default, no ports belong to any trunk. A grayed
out port indicates that it has been configured for port mirroring (destination or source port),
or that it is set to half duplex. The user is not allowed to perform any trunk membership
configuration on this port until the port is removed from the mirroring configuration or is
reconfigured to full duplex mode.
Figure 30 TRK1, TRK2, and TRK3 are configured in Disabled Mode.
