Protection switching over a virtual link aggregation
First Claim
1. A switch, comprising:
- one or more ports;
a link management module configured to;
operate a protected virtual link aggregation group as a protected logical channel, wherein the protected virtual link aggregation group comprises a first and a second aggregate link groups, and wherein an aggregate link group comprises a plurality of aggregated links operating as a logical channel;
operate the first aggregate link group as an active aggregate link group of the protected virtual link aggregation, wherein the first aggregate link group comprises at least a first port of the one or more ports of the switch, and wherein forwarding is enabled via the first port; and
operate the second aggregate link group of the protected virtual link aggregation as a standby for the first aggregate link group, wherein the second aggregate link group comprises at least a second port of the one or more ports of the switch, and wherein forwarding is disabled via the second port;
wherein, in response to being operational, the logical channel of the first aggregate link group represents the protected logical channel.

Abstract
One embodiment of the present invention provides a switch. The switch comprises one or more ports and a link management module. The link management module operates a first aggregate link group as an active aggregate link group of a protected virtual link aggregation. This protected virtual link aggregation operates as a single logical channel. An aggregate link group comprises a plurality of logically aggregated links. The first aggregate link group, which represents the logical channel, comprises at least a first port of the one or more ports of the switch. The link management module also operates a second aggregate link group of the protected virtual link aggregation as a standby for the first aggregate link group. The second aggregate link group comprises at least a second port of the one or more ports of the switch. Forwarding is enabled via the first port and disabled via the second port.

21. A system, comprising:
-
one or more ports; a processor; a memory storing instructions that when executed by the processor cause the system to perform a method, the method comprising; operating a protected virtual link aggregation group as a protected logical channel, wherein the protected virtual link aggregation group comprises a first and a second aggregate link groups, and wherein an aggregate link group comprises a plurality of aggregated links operating as a logical channel; operating the first aggregate link group as an active aggregate link group of a protected virtual link aggregation group, wherein the first aggregate link group comprises at least a first port of the one or more ports of the system, and wherein forwarding is enabled via the first port; and operating the second aggregate link group of the protected virtual link aggregation as a standby for the first aggregate link group, wherein the second aggregate link group comprises at least a second port of the one or more ports of the system, and wherein forwarding is disabled via the second port; wherein, in response to being operational, the logical channel of the first group represents the protected logical channel.
