1 irf configuration note: the following s5120-ei switch models support interface cards and can form irf fabrics: s5120-28c-ei, s5120-52c-ei, s5120-28c-pwr-ei, and s5120-52c-pwr-ei. You can establish an irf fabric among s5120-ei switches of these models. Irf overview the h3c intelligent resilient fra...

14 note: • to realize irf link redundancy and load sharing and increase the bandwidth and reliability of irf links, bind one irf port to multiple physical irf ports by repeatedly executing the port group interface command. You can bind up to two physical irf ports to an irf port. The physical ports ...
