Abstract

A network. At least some embodiments are a network including a first root node connected to a first port of a first switch and a second root node connected to a first port of a second switch. A first link is connected to a second port of the first switch and connected to a second port of the second switch. A second link is connected to a third port of a first switch and connected to a third port of the second switch.

Claims

1. A method comprising:

notifying, by a first network device of a link segment disconnection, a first root node, wherein the first root node comprises a nearest root node to the first network device on a first connected link segment;

notifying, by a second network device of the link segment disconnection, a second root node, wherein the second root node comprises a nearest root node to the second network device on a second connected link segment;

enumerating, by the first root node, each network device on the first connected link segment; and

enumerating, by the second root node, each network device on the second connected link segment.

2. The method of claim 1 further comprising detecting the link segment disconnection by the first network device.

3. The method of claim 2 further comprising detecting the link segment disconnection by the second network device.

4. A non-transitory machine-readable storage medium comprising executable instructions that, when executed, cause one or more processors to:

responsive to notification of a link segment disconnection;

enumerate, each network device on a first link segment connected to a first root node, wherein the notification of the link segment disconnection is received by the first root node on the first link segment; and

enumerate each network device on a second link segment connected to a second root node, wherein the notification of the link segment disconnection is received by the second root node on the second link segment.
