VIRTUAL EXTENSIBLE LAN TUNNEL KEEPALIVES

摘要

One embodiment of the present invention provides a switch that is a member of a fabric switch. The switch includes a keepalive response module that identifies a keepalive response packet that does not correspond to any keepalive packet previously transmitted by the switch. The switch also includes a switch identifier extraction module that extracts a switch identifier from a payload of the keepalive response packet, where the switch identifier corresponds to another member switch in the fabric switch. The switch further includes a forwarding module that constructs a packet that includes the payload and is destined to the other member switch.

主权项

1. A switch, comprising:
one or more ports adapted to receive packets encapsulated based on a first protocol, wherein the switch is a member of a fabric switch; a keepalive response module adapted to identify a keepalive response packet that does not correspond to any keepalive packet previously transmitted by the switch; a switch identifier extraction module adapted to extract a switch identifier from a payload of the keepalive response packet, wherein the switch identifier corresponds to another member switch in the fabric switch; and a forwarding module adapted to construct a packet that includes the payload and is destined to the other member switch.
