Abstract
In one embodiment, a method includes receiving at a network device, a packet from a component in a virtual network device, the packet transmitted across a link aggregation bundle connecting the virtual network device to the network device and indicating if the component is a master component in the virtual network device, and determining if an error exists in operation of the component as the master component or a slave component. An apparatus for assigning services to physical links in an aggregated link bundle is also disclosed.
Claims20
A method comprising:
- receiving at a network device, a packet from a component in a virtual network device, the packet transmitted across a link aggregation bundle connecting the virtual network device to the network device, and indicating if the component is a master component in the virtual network device;
- and
- determining if an error exists in operation of the component as the master component or a slave component.
An apparatus comprising:
- a processor configured for processing a packet received from a component in a virtual network device, the packet transmitted across a link aggregation bundle for connecting the virtual network device to the apparatus, the packet indicating if the component is a master component in the virtual network device, and determining if an error exists in operation of the component as the master component or a slave component;
- and
- memory for storing a status of the component as the master or slave component.
An apparatus comprising:
- a processor for defining preferences for assigning services to physical links in an aggregated bundle of physical links connecting the apparatus to a network device, and transmitting a packet comprising said preferences to the network device;
- and
- memory for storing said preferences.
