Re: STP question// LACP

No TCN since STP is running at the PortChannel level. It will however send
a trap and will how up in your local log buffer:

If a segment within an EtherChannel fails, traffic previously carried over
the failed link switches to the remaining segments within the EtherChannel.
When a failure occurs, the EtherChannel feature sends a trap that
identifies the switch, the EtherChannel, and the failed link.

Regarding LACP an suspended link. Could you please provide interface
configs from all ports on both sides? Are they all identical?
