Configure two GE ports on the TN11TBE as full duplex and manually configure the two ports into an LAG. Disable the laser of one port. The LAG, however, is not reconfigured. Why?
Set the port working mode in the LAG to auto-negotiation, or configure the LAG as a static LAG.
When the laser of a port in the LAG is disabled, the opposite port becomes linkdown, but the local port is still linkup. The manually configured LAG determines the working status of ports according to the link status. Therefore, the port is still a working port, because the link status of the port does not change.
