NB i have fibre interconnecting switches.. i need to add ethernet to increase bandwidth but now am confused. Please advise.. thanks Sun, 12 Jun 2016 18:44:00 GMT https://community.extremenetworks.com/t5/network-architecture-design/timeout-on-switch-interconnection/m-p/13078#M482 Joe_Lwe 2016-06-12T18:44:00Z https://community.extremenetworks.com/t5/network-architecture-design/timeout-on-switch-interconnection/m-p/13079#M483 You need to build ether channel on Cisco side, and lacp lagg on extreme side. Also, you don't need to use crossover patches, because ports are auto MDI/MDI-x Sun, 12 Jun 2016 18:55:00 GMT https://community.extremenetworks.com/t5/network-architecture-design/timeout-on-switch-interconnection/m-p/13079#M483 Nick_Yakimenko 2016-06-12T18:55:00Z https://community.extremenetworks.com/t5/network-architecture-design/timeout-on-switch-interconnection/m-p/13080#M484 If you want to use two (or more) parallel connections between two switches to increase bandwidth, you need to configure port sharing (also known as a Link Aggregation Group (LAG) or a Port-Channel).
