Claim 14:
15. A network device comprising:
a port;
a clock;
one or more computer processors; and
a computer-readable storage medium comprising instructions for controlling the one or more computer processors to be operable to:
synchronize the clock in the network device with a clock in a first device on a first logical network, including exchanging first messages between a port on the network device and a port on the first device, wherein the first messages include 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, wherein the second messages include an identifier 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.
