配置EvPC（增强的vPC），下面两个FEX可以同时被两个N5K管理。
注意：FEX只支持静态的Channel-group（mode on）
N5K-1配置：
配置FEX
N5K-1（config）#feature fex
N5K-1（config）#inter e1/20-21
N5K-1（config-if-range）#channel-group 101
N5K-1（config）#inter Port-channel 101
N5K-1（config-if）#sw mode fex-fabric
N5K-1（config-if）#fex associate 101
N5K-1（config-if）#vpc 101
N5K-1（config）#int e1/22-23
N5K-1（config-if-range）#channel-group 102
N5K-1（config）#inter port-channel 102
N5K-1（config-if）#sw mode fex-fabric
N5K-1（config-if）#fex associate 102
N5K-1（config-if）#vpc 102
N5K-1（config）#cfs ipv4 distribute
N5K-1（config）#configure sync
N5K-1（config-sync）#switch-profile cisco
N5K-1（config-sync-sp）#sync-peers destination 10.1.1.62
N5K-1（config-sync-sp）#inter e101/1/1,e101/1/18,e102/1/1
N5K-1（config-sync-sp-if-range）#speed 1000
N5K-1（config-sync-sp-if-range）#channel-group 300 mode active
N5K-1（config-sync-sp-if-range）#exit
N5K-1（config-sync-sp）#inter port-channel 300
N5K-1（config-sync-sp-if）#sw mode trunk
N5K-1（config-sync-sp-if）#spanning-tree port type edge trunk
N5K-1（config-sync-sp-if）#exit
N5K-1（config-sync-sp）#verify
Verification Successful
N5K-1（config-sync-sp）#commit
建议：不要使用configure sync功能配置要启动FCoE功能的接口，例如e101/1/1,e102/1/1
N5K-2配置：
配置N5K-2的配置同步
N5K-2（config）#cfs ipv4 distribute
N5K-2（config）#configure sync
N5K-2（config-sync）#switch-profile cisco
N5K-2（config-sync-sp）#sync-peers destination 10.1.1.61
配置FEX
N5K-2（config）#feature fex
N5K-2（config）#inter e1/20-21
N5K-2（config-if-range）#channel-group 102
N5K-2（config）#inter Port-channel 102
N5K-2（config-if）#sw mode fex-fabric
N5K-2（config-if）#fex associate 102
N5K-2（config-if）#vpc 102
N5K-2（config）#int e1/20-21
N5K-2（config-if-range）#channel-group 101
N5K-2（config）#inter port-channel 101
N5K-2（config-if）#sw mode fex-fabric
N5K-2（config-if）#fex associate 101
N5K-2（config-if）#vpc 101
