Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 7:
8. A non-transitory computer-readable storage medium having stored thereon computer executable instructions, which when executed by a processor in a network device, cause the processor to:
synchronize a clock in the network device with a clock in a first device on a first logical network, including exchanging first messages between a port of the network device and a port on the first device, the first messages having an identifier that identifies the first logical network;
synchronize the clock in the network device with a clock in a second device on a second logical network different from the first logical network, including exchanging second messages between the port of the network device and a port on the second device, the second messages having an identifier with the second messages that identifies the second logical network;
determine a first port state for the port that corresponds to the first logical network based at least on clock data of the network device and clock data obtained from the first synchronizing; and
determine a second port state of the port that corresponds to the second logical network based at least on the clock data of the network device and clock data obtained from the second synchronizing.
