Abstract
A computer implemented method, data processing system, and a computer program product are provided for processing packets in switches. A first switch receives a packet from a network that is to be directed to a host. A determination is made as to whether all of the ports connected from the first switch to the host have failed. If all of the ports from the first switch to the host have failed, the packet is sent through a backup port connected to a second switch, which sends the packet to the host.
Claims20
A computer implemented method for processing packets in switches, the computer implemented method comprising:
- receiving a packet for a host from a network in a first switch;
- determining if all link aggregation ports connected from the first switch to the host have failed;
- and
- if all of the link aggregation ports on the first switch have failed, sending the packet through a backup port connected to a second switch, wherein the second switch sends the packet to the host.
A data processing system comprising:
- a host;
- a first switch;
- and
- a second switch, wherein the first switch executes a set of instructions to receive a packet for the host from a network;
- determine if all link aggregation ports connected from the first switch to the host have failed;
- and, if all of the link aggregation ports on the first switch have failed, send the packet through a backup port connected to the second switch, wherein the second switch executes a set of instructions to send the packet to the host.
A computer program product comprising:
- a computer usable medium including computer usable program code for processing packets in switches, the computer program product including:
- computer usable program code for receiving a packet for a host from a network in a first switch;
- computer usable program code for determining if all link aggregation ports connected from the first switch to the host have failed;
- and
- computer usable program code for, if all of the link aggregation ports on the first switch have failed, sending the packet through a backup port connected to a second switch, wherein the second switch sends the packet to the host.
