Abstract
An active-standby virtual port channel mechanism may be provided, where at any point only one virtual port channel link would be active. Upon failover of the active, a fast failover mechanism is employed to move active traffic to a standby port channel link.
Claims20
A method comprising:
- establishing a virtual port channel with a first leg and a second leg;
- configuring the first leg as an active leg;
- and
- configuring the second leg as a standby leg, wherein the standby leg does not accept or forward transmitted packets.
1 more element
A method comprising:
- establishing a virtual port channel connecting a plurality of network devices to a plurality of core networks, wherein the virtual port channel comprises:
- an active virtual port channel leg associated with a first switch device;
- and
- a standby virtual port channel leg associated with a second switch device, wherein the first switch device and the second switch device are connected across a peer link.
1 more element
An apparatus comprising:
- a memory;
- and
- a processor, wherein the processor is configured to:
- maintain a status indicating that a leg associated with the virtual port channel and the apparatus is one of:
- active or standby;
- detect a failure when the leg associated with the virtual port channel and the apparatus is active;
- communicate with a switch device associated with a virtual port channel across a peer link when a failure of the active leg.
