Should loop guard apply on etherchannel which is port channel if only one port configured as channel group

[Maivoko]

i find that loop guard is per port basis and should not apply on etherchannel on shared link.

in another words, it can not apply on etherchannel if two or more ports configured as etherchannel 

Should loop guard apply on etherchannel which is port channel interface if only one port configured as channel group?

The command should be applied globally.

see link:

spanning-tree loopguard default

this is wrong, only root port apply
i am asking etherchannel of only one port
