Subnet Commands
subnet-create
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. It removes the suboptimal routing inefficiencies associated with separate centralized gateways.
This command allows you to assign subnets to VLANs and VXLANs.

subnet-delete
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. It removes the suboptimal routing inefficiencies associated with separate centralized gateways.
This command allows you to delete a subnet.
Syntax subnet-delete
name name-string |
Specify the name of the subnet. |

CLI network-admin@switch > subnet-delete name subnet-one vnet vnet-1 vrf vrf-1
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.
