What all are the possiblities a port channel ( all the ports are in access mode ) creates loop in the networks ?
Thank you

When one end of an EtherChannel has more members than the other, the unmatched ports enter the standalone state. In a topology that is not protected from Layer 2 loops by the spanning tree protocol (STP), a port in the standalone state can cause significant network errors. For LACP EtherChannels with Release 12.2(33)SXI3 and later releases, you can enter the
port-channel standalone-disable
interface configuration mode command to put ports into the suspended state instead of the standalone state. See the
"Configuring LACP Port-Channel Standalone Disable" section. When one end of an EtherChannel

Hi,
Reza is absolutely correct. You may be interested to read the following thread:

In quite a large scale, we have discussed how an improper configuration of EtherChannels leads to switching loops. Note that it is not important if the EtherChannel operates as an access or a trunk port.
Best regards,
Peter
