I notice you have one interface assigned to Po1 and three assigned to Po2. Is that what you want?

If so, please check the syslog messages when you shut/no shut the interface. They should provide a message indicating the reason for suspending the portchannel for that interface.

Hello,

This is syslog : %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet1/0/22, changed state to down

Thanks for your help

I believe you will need to shut/no shut the whole etherchannel to get it to trigger the error condition again.

I did and I got the log above, but when I change the interface Gi1/0/22 to Port-channel1, it's work fine .

Thanks

That's what I was alluding to in my initial reply. Check your cabling - it may well be that you have Gi1/0/21 and /22 cabled to the same host portchannel.

When you try to tell the switch they are on different etherchannels, the negotiation process informs the switch "no, they aren't" and you get the suspended state as a result.
