This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - LACP is the open standard (802.3ad) using Active/Passive modes; at least one side must be Active to form a channel. - PAgP is Cisco-proprietary, using Desirable/Auto modes; at least one side must be Desirable for a channel to form. - The Static 'On' mode uses no negotiation and poses a risk of Layer 2 loops if misconfigured on one side. - All physical ports in an EtherChannel bundle must have identical configurations for speed, duplex, and VLAN settings. - LACP and PAgP are not interoperable; you cannot form a channel between a switch running PAgP and one running LACP.
