CPC H04L 61/103 (2013.01) [H04L 47/20 (2013.01); H04L 47/22 (2013.01); G06F 13/36 (2013.01); G06F 2213/3808 (2013.01); H04L 2101/622 (2022.05)] | 17 Claims |
1. A computer-implemented method of managing failover between information handling systems, the method comprising:
receiving, at an interface of a smart network interface card (smartNIC) of a primary information handling system, a packet, the primary information handling system communicatively coupled to a secondary information handling system, the smartNIC associated with a first power domain separate than a second power domain of a central processing unit (CPU) of the primary information handling system;
determining whether the packet was transmitted by a network interface card (NIC) of the secondary information handling system;
determining that the packet was transmitted by the NIC of the secondary information handling system, and in response, determining whether the packet is an address resolution protocol (ARP) request;
determining that the packet is an ARP request, and in response, cloning a medium access control (MAC) address of the NIC of the secondary information handling system at the smartNIC of the primary information handling system, including:
adjusting a power state of the secondary information handling system and a first power state of the first power domain of the smartNIC to an on-power state to clone the MAC address of the NIC of the secondary information handling system prior to adjusting a power state of the second power domain of the primary information handling system to an on-power state; and
forwarding the ARP request to a uplink connection.
