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.

Usage Use this command to create a subnet.
Examples To create a subnet, subnet-one, use the following syntax:
CLI (network-admin@switch) > subnet-create name subnet-one scope fabric vnet vnet-1 vlan 35 vxlan 1001 network 172.21.16.0 netmask 255.255.255.0 vrf vrf-1 anycast-gw-ip 172.21.16.1
Additional Information In the above example, 172.21.16.1 acts as a default gateway for hosts in VLAN 35 / VXLAN 1001.
