Hello,
If you modify the configuration of a physical member in an Etherchannel bundle, this physical interface may be suspended and temporarily removed from the bundle if its configuration is not identical or compatible with the configuration of the Port-channel interface.
As a matter of rule, after physical ports are bundled into an Etherchannel, all further configuration shall be performed on the Port-channel interface only, and not on physical interfaces anymore.
Best regards,
Peter
