subnet-modify
To facilitate optimal east-west routing while supporting transparent virtual machine mobility, leaf switches are assigned the same gateway IP, and MAC address for each locally defined subnet. Having the same gateway IP, and MAC address helps ensure a default gateway presence across all leaf switches, and removes the suboptimal routing inefficiencies associated with separate centralized gateways.
This command allows you to modify a subnet.
