Abstract
In some embodiments, a data packet may be received at a leaf switch. A port-channel associated with a destination port for the data packet may be identified, and the data packet may be transmitted to the destination port via the identified port-channel.
Claims14
An apparatus comprising:
- a plurality of physical network ports;
- a memory storage;
- and
- a processor coupled to the memory storage, the processor operative to:
- receive a data packet associated with a destination port-channel,
- determine whether the destination port-channel is associated with at least one of the plurality of physical network ports, and
- in response to determining that the destination port-channel is not associated with at least one of the plurality of physical network ports:
- identify a global index associated with the destination port-channel;
- set a header value in the data packet to the identified global index associated with the destination port-channel;
- and
- forward the data packet to a fabric switch associated with the destination port-channel.
