same time. Those member ports which are not work ports are standby to
become work port if any current work port fails to operate. This transition
takes about 30 seconds. Each member port can be set LACP Passive or
LACP active as described below:
LACP Passive : The port does not initiate the LACP negotiation, but it
does understand the LACP packet. It will reply to the received LACP
packet to eventually form the link aggregation if its link partner is
requesting to do so (in active state).
LACP Active : The port is willing to form an aggregate link, and initiate
the negotiation. The link aggregate will be formed if its link partner is
running in LACP active or passive mode.
There are only three valid combinations to run the LACP link aggregate
as follows:
•
disabled to disabled state (forced link aggregate without LACP)
•
active to active state
•
active to passive state
Rules of trunking
1. Up to seven trunk groups (trunk ports) can be created.
2. Each trunk group can be composed of up to 4 member ports.
3. The member port can be one of Port 1 ~ Port 24 and G1 - G2 port.
4. One switched port only can belong to one trunk group.
5. If VLAN group exist, all members of one static trunk group must be
in same VLAN group.
6. LACP operation requires member ports in full-duplex mode.
7. In a static trunk group (LACP disabled), four work ports are aggre-
gated at the same time.
8. In an LACP trunk group, maximal two work ports can be aggregated
at the same time.
