Etherchannel Standalone Status

I have a link between the data center and a client through two dark fibers. I have configured etherchannel lacp Active - Active.

When testing with the client disconnecting the links (one at a time) to see how the etherchannel behaved port side was disconnected showed "no connect" on the "show interface command" and the other side that kept the cable connected "connect" is displayed. The state of this port etherchannel was standalone (I).

I searched information to know the meaning and behavior of etherchannel in this state but I could not find details.

Anyone know where I can find information etherchannel states that meaning has to be in that state for channel usage.

best regards

Etherchannel Standalone Status


The port is not bundled in an EtherChannel. The port functions as a standalone data port. The port can send and receive BPDUs and data traffic.

Note 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.
