Static Trunk Mode; Lacp Trunk Modes - HP 1810-24G Management And Configuration Manual

Static Trunk Mode

A static trunk interface does not require a partner system to be able to aggregate its member ports.
In this mode it does not transmit or process received LACPDUs; member ports do not transmit
LACPDUs and all the LACPDUs received are dropped. However, the ports in a static trunk on one
device must be connected to ports on another device that is also configured for the same static
trunk.
In Figure 31, all trunk modes are configured in Static mode.

CAUTION:
you remove a port from a trunk where spanning tree is not in use, HP recommends that you first
disable the port or disconnect the link on that port.

LACP Trunk Modes

There are two types of LACP Trunk Modes: LACP Active and LACP Passive. In LACP Active, a trunk
is initiated and maintained by periodic exchanges of LACPDUs. In LACP Passive, a trunk only
participates if the other end sends LACPDUs (other end is LACP Active).
In Figure 32 TRK1 is configured in LACP Active Mode and TRK2 is configured in LACP Passive
Mode.
Removing a port from a trunk can create a loop and cause a broadcast storm. When
