D-Link Document - User Manual advantage of wide bandwidth, the I/O traffic remains operating until all physical links fail. If any link is restored, it will be added to the link group automatically. LACP The Link Aggregation Control Protocol (LACP) is a part of IEEE specification 802.3ad. It allows the bundling of several physical ports together to form a single logical channel. A network switch negotiates an automatic bundle by sending LACP packets to the peer. Theoretically, the LACP port can be defined as active or passive. D-Link controllers implement it as active mode which means that LACP port sends LACP protocol packets automatically. Please note that you are using the same configurations between the D-Link controller and gigabit switch. The usage occasion of LACP:  It's necessary to use LACP in a network environment of multiple switches. When adding new devices, LACP will separate the traffic to each path dynamically. Trunking Trunking is not a standard protocol. It defines the usage of multiple iSCSI data ports in parallel to increase the link speed beyond the limits of any single port. The usage occasion of Trunking:  This is a simple SAN environment. There is only one switch to connect the server and storage, and there will be no extra server added in the future.  There is a request for monitoring the traffic on the trunk in the switch.

link is restored, it will be added to the link group automatically.
LACP
The Link Aggregation Control Protocol (LACP) is a part of IEEE specification 802.3ad. It allows the
bundling of several physical ports together to form a single logical channel. A network switch
negotiates an automatic bundle by sending LACP packets to the peer. Theoretically, the LACP port
can be defined as active or passive. D-Link controllers implement it as active mode which means
that LACP port sends LACP protocol packets automatically. Please note that you are using the
same configurations between the D-Link controller and gigabit switch.
The usage occasion of LACP:
It’s necessary to use LACP in a network environment of multiple switches. When adding new
devices, LACP will separate the traffic to each path dynamically.
Trunking
Trunking is not a standard protocol. It defines the usage of multiple iSCSI data ports in parallel to
increase the link speed beyond the limits of any single port.
The usage occasion of Trunking:
This is a simple SAN environment. There is only one switch to connect the server and
storage, and there will be no extra server added in the future.
There is a request for monitoring the traffic on the trunk in the switch.
