4. 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 J4812A HP Procurve Switch 2512 J4813A HP Procurve Switch 2524 Note Ports 1 2 5 6 13 amp 17 Switch A we are LACP active 12s os Switch B Copyright Hewlett Packard Company 2000 Page 1 All rights reserved WARNING The example configurations below were created from
