Cisco PAgP Configuration!!!????????????

答：PAGP 和 LACP 的协商模式类似：PAGP 的协商模式为“auto”和“desirable”，LACP 的协商模式为“passive”和“active”。 这些模式规定了形成 EtherChannel 的协商过程如何进行。

什么是 PAgP 协议？ PAgP（端口聚合协议）是思科专有的链路聚合协议，仅支持在思科设备或少数获得授权的第三方交换机上使用。 PAgP 通过能在以太网接口间交换协议数据包，自动建立 EtherChannel。

Port Aggregation Protocol (PAgP) is a Cisco Systems proprietary networking protocol, which is used for the automated, link aggregation of Ethernet switch ports, known as an EtherChannel.

PAGP是Cisco專有的協議，只能在Cisco交換機或供應商許可的支持PAGP的交換機上運行。 通過在乙太網埠之間交換PAGP數據包，PAGP有助於自動創建Etherchannel。

Port Aggregation Protocol or PAgP is an EtherChannel technology that is a Cisco proprietary protocol. It is a form of logical aggregation of Cisco Ethernet switch ports, and it enables data/traffic load balancing.

Port Aggregation Protocol (PAGP) is a cisco-proprietary protocol also known as aggregation protocol. It allows the creation of EthernetChannel automatically by exchanging PAGP packets between ports.
