Dynamic LACP Trunking
The example configurations below provide dynamic trunking between two HP Procurve Series 2500
Switches (Switch A and Switch B) using LACP (802.3ad) as the trunking protocol.
Another benefit, besides dynamic trunk formation, of an LACP trunk is port redundancy. If one of
the operational ports fails then one of the redundant "standby" ports becomes operational without
any user intervention.
To create a dynamic LACP trunk, configure ports at one end of the link to be LACP active - and
ensure that LACP is enabled at the other end.
Switch A is configured to provide six LACP active ports. Since the Series 2500 Switches support
one trunk group of up to four ports, the other two ports will be redundant "standby" ports.
Switch B is in its default configuration. As stated above for a dynamic LACP trunk, once one end of
the link is configured for LACP active, the only other requirement is that the port at the other end of
the link must have LACP enabled. Since the Series 2500 Switches have LACP enabled by default,
there is no need to modify Switch B from its default configuration.
This configuration example applies to the following products:
