craft subnet create --cidr 10.10.1.0/24 --draft-mode
One of the most coveted skills in modern networking is dynamic subnet resizing without downtime. Using a Subnetwork Craft Terminal, the process looks like this: subnetwork craft terminal
# Step 1: Check current subnet utilization
craft telemetry scan --subnet 10.10.0.0/24
# Output: 85% utilization. 200 IPs in use.
The SCT is pinned to a single subnetwork identifier (VLAN, VNI, or subnet prefix). It does not route between subnets—that’s the router’s job. This purity ensures that any packet seen by the SCT must be present in that broadcast domain, eliminating cross-subnet confusion. craft subnet create --cidr 10
The SCT connects to the network infrastructure using several standard interfaces: Symptom: VM in VNI 5001 cannot reach gateway
Symptom: VM in VNI 5001 cannot reach gateway. VTEPs show no errors.
SCT action: Deploy an SCT in the overlay subnet (VNI 5001) and send a crafted GARP from a test MAC. Check if the underlay (IP/ UDP) delivers the encapsulated frame. If not, your multicast group or head-end replication list is broken.
