Catalyst設定

passive同士だとLAGにならないため注意。active同士だと可能。
EtherChannelにVlanを割り当てる場合、作成されたPort-channelの論理i/fに設定。

Switch123# configure terminal
Switch123(config)# interface range gi0/4-5
Switch123(config-if-range)# channel-protocol lacp
Switch123(config-if-range)#channel-group 1 mode {active,passive}
Switch123(config-if-range)# end
Switch123(config)# interface Port-chaannel 1
Switch123(config-if)# switchport access vlan 60

使用しているEtherChannelプロトコルなどを確認
