Nov 23, 2021 · PAGP allows the switches to learn the identity of its associates’ apt of supporting PAGP and then it dynamically divides the similarly configured ports into a single logical channel or aggregate port.

Jun 26, 2024 · Quick Definition: Link Aggregation Control Protocol (LACP) and Port Aggregation Protocol (PAgP) are layer-2 protocols used to implement link aggregation. LACP is an industry-standard protocol supported by most network vendors, offering flexibility and cross-stack aggregation capabilities.

Apr 11, 2024 · PAgP, or Port Aggregation Protocol, is Cisco's proprietary solution for link aggregation. Like LACP, PAgP's goal is to combine multiple physical links into a single logical channel, boosting the overall bandwidth and providing redundancy.

Nov 14, 2023 · LACP is a standard protocol defined by IEEE 802.3ad, while PAgP is a proprietary protocol developed by Cisco. LACP and PAgP have some differences, among others in terms of compatibility, frame format, mode of operation, and number of ports supported.

PAgP is Cisco’s proprietary EtherChannel protocol – Port Aggregation Protocol. But given a standardized approach we often lean towards a standardized approach. In my mind these are equal, except for the fact that one is standard; one is proprietary.

Compare LACP vs PAgP for network link aggregation. Understand protocols, benefits, and differences for better setups.

Apr 1, 2025 · While configuring EtherChannel across devices (Switches/Routers), 2 most widely used negotiation protocols are PAgP and LACP. While PAgP is Cisco proprietary , LACP is Open standard and supported by most of the vendors.

When configuring Etherchannel across network devices such as switches or routers, the two most widely used negotiation protocols are LACP (Link Aggregation Control Protocol) and PAGP (Port Aggregation Protocol). How they differ from each other when aggregating links and redistributing the load in case of a link fail for any network?

When configuring Etherchannel across network devices such as switches or routers, the two most widely used negotiation protocols are LACP (Link Aggregation Control Protocol) and PAGP (Port Aggregation Protocol).

PAGP provides dynamic negotiation of link aggregation between switches, which allows for optimal bandwidth utilization and link redundancy. This is achieved by dynamically adding or removing links from the LAG group based on the state of the links.
