Claim 14:
15. A program product comprising a non-transitory computer readable storage medium storing program code, the program code configured to be executable by a processor of an unmanaged switch to perform operations comprising:
receiving, at an unmanaged switch, an unsolicited link aggregation control protocol (“LACP”) protocol data unit (“PDU”) on each port of two or more connections to be linked in a link aggregation group (“LAG”) from a managed switch, the ports of the two or more connections in the unmanaged switch, the unmanaged switch being unconfigured for LACP prior to receiving the unsolicited LACP PDU and connected over the two or more connections to the managed switch, wherein the managed switch is configured for LACP and is configured to transmit LACP PDUs to the unmanaged switch to initiate and maintain a LAG on the unmanaged switch;
in response to determining, at the unmanaged switch, that the ports that received an unsolicited LACP PDU are unconfigured for LACP:
configuring each port receiving an LACP PDU for LACP;
creating a LAG comprising the two or more connections to the managed switch connected to the ports that received the LACP PDUs; and
starting an LACP timer; and

in response to determining, at the unmanaged switch, that the LACP timer has expired, clearing the LACP configuration of the ports configured for LACP, wherein the LACP timer expires in response to the ports in the LAG not receiving additional LACP PDUs prior to expiration of an LACP timer period,
wherein a system administrator is unable to use LACP commands to manually configure ports for a LAG on the unmanaged switch.
