Task 07 — Logical Network Creation

DOCUMENT CATEGORY: Implementation Guide SCOPE: Phase 06 — Post-Deployment | Azure Local PURPOSE: Create all logical networks defined in variables.yml. Each entry is provisioned as an Azure resource on the cluster's Hyper-V vSwitch, providing the network layer for Arc VM deployment — with Static IP pools or Dynamic (DHCP) allocation, VLAN isolation, and optional static routes, exactly as configured.

Objective: Create every logical network entry in networking.logical_networks[] on the Azure Local cluster. The Orchestrated script reads the YAML config and deploys each network as-configured — Static or Dynamic, with or without routes. The Standalone script has hardcoded values for one-off use or when running outside the toolkit.

This task creates the VM network layer — not the physical switch config

Logical networks bind to a Hyper-V vSwitch (already on the cluster from deployment) and map to a physical VLAN. Switch VLAN configuration and network_intents were completed during Phase 05. This task creates the Azure resource representations.

Prerequisites:

• Azure Local cluster deployed and Arc-enabled (Phase 05 complete)
• CSV volumes created and healthy (Task 05 complete)
• az stack-hci-vm CLI extension installed: az extension add --name stack-hci-vm
• Azure identity authenticated: az login or Connect-AzAccount
• powershell-yaml module installed: Install-Module powershell-yaml -Scope CurrentUser
• networking.logical_networks block populated in variables.yml

Create Logical Networks

Azure Portal

When to use: Creating a single logical network, visually confirming VLAN and IP pool details, or when CLI access is unavailable.

Prerequisites: Contributor rights on the cluster resource group in the Azure Portal.

---

Steps (repeat for each logical network):

1. Navigate to your Azure Local cluster resource: Azure Portal → Azure Local → iic-clus01

2. In the left navigation, select Resources → Logical networks

3. Click + Create

4. On the Basics tab, fill in:

• Subscription: a1b2c3d4-e5f6-7890-abcd-ef1234567890
• Resource group: rg-iic01-azl-eus-01
• Logical network name: e.g. ln-iic01-management-100
• Custom location: cl-iic01
• Virtual switch name: ConvergedSwitch(hci)

Finding the vSwitch name

If you're unsure of the vSwitch name, run the following on any cluster node:

Invoke-Command -ComputerName iic-01-n01 -ScriptBlock { Get-VMSwitch | Select-Object Name, SwitchType }

5. Click Next: Network configuration

6. On the Network configuration tab:

• VLAN ID: enter the VLAN number (e.g. 100)
• Click + Add subnet
• Subnet name: default
• IP allocation method: Static or Dynamic

For Static networks:

• Address prefix: e.g. 10.100.0.0/24
• Default gateway: e.g. 10.100.0.1
• DNS servers: e.g. 10.100.0.10, 10.100.0.11
• Click + Add IP pool:
• Pool name: e.g. pool-mgmt-vms
• Start IP: e.g. 10.100.0.50
• End IP: e.g. 10.100.0.200

For Dynamic (DHCP) networks:

• Address prefix, IP pools, and gateway are not required

• Supply DNS servers under DHCP options

• Click Add

7. Click Review + create → Create

8. Repeat for each additional logical network in networking.logical_networks[].

Standard IIC logical networks — example portal values:

Network name	VLAN	Subnet	Gateway	IP pool range	Alloc
ln-iic01-management-100	100	10.100.0.0/24	10.100.0.1	10.100.0.50–200	Static
ln-iic01-production-200	200	10.200.0.0/24	10.200.0.1	10.200.0.50–250	Static
ln-iic01-avd-300	300	(DHCP)	(DHCP)	(DHCP)	Dynamic

Orchestrated

When to use: Automated or repeatable deployment. Reads all logical network definitions from networking.logical_networks[] in variables.yml and creates every enabled entry. Entries with enabled: false are skipped. Already-existing networks are skipped. Run from the management server (toolkit repo root).

#Requires -Version 5.1
<#
.SYNOPSIS
 Orchestrated: creates all logical networks defined in variables.yml.

.DESCRIPTION
 Phase 06 — Post-Deployment | Task 07 — Logical Network Creation

 Reads every entry from networking.logical_networks[] in the infrastructure YAML
 and calls az stack-hci-vm network lnet create for each one. Entries with
 enabled: false are skipped. Networks that already exist are skipped.

 Both Static (IP pools + default gateway route) and Dynamic (DHCP) allocation
 methods are supported. Static routes defined in routes[] are appended to the
 subnet configuration. The Hyper-V vSwitch name is read from
 compute.azure_local.vm_switch_name; when empty, it is auto-discovered from the
 first available cluster node via Get-VMSwitch over PSRemoting.

.PARAMETER ConfigPath
 Path to infrastructure YAML. Defaults to config\variables.yml in CWD.

.PARAMETER Credential
 Credential used for PSRemoting vSwitch discovery. If omitted, resolved via
 Key Vault (Resolve-KeyVaultRef) then interactive Get-Credential prompt.
 Not needed when vm_switch_name is populated in the config.

.PARAMETER TargetNode
 Limit vSwitch auto-discovery to specific node(s). If empty, uses the first
 key in compute.nodes. Ignored when vm_switch_name is set in config.

.PARAMETER WhatIf
 Dry-run mode: logs all planned operations without making any changes.

.PARAMETER LogPath
 Override log file path. Default: logs\task-07-logical-network-creation\
 <YYYY-MM-DD_HHmmss>_LogicalNetworks.log (relative to CWD).

.EXAMPLE
 # Run from repo root with default config:

Validation

After all logical networks are created, confirm they are in a Succeeded provisioning state and are visible on the cluster's Logical networks blade.

List all logical networks in the resource group

az stack-hci-vm network lnet list `
 --subscription a1b2c3d4-e5f6-7890-abcd-ef1234567890 `
 --resource-group rg-iic01-azl-eus-01 `
 --output table

Check a specific logical network

az stack-hci-vm network lnet show `
 --subscription a1b2c3d4-e5f6-7890-abcd-ef1234567890 `
 --resource-group rg-iic01-azl-eus-01 `
 --name ln-iic01-management-100 `
 --query "{Name:name, State:provisioningState, VLAN:properties.networkType}" `
 --output table

Expected results:

Name	State	VLAN
ln-iic01-management-100	Succeeded	100
ln-iic01-production-200	Succeeded	200
ln-iic01-avd-300	Succeeded	300

Logical network stuck in "Updating" or "Failed"

If a logical network enters Failed state or stays in Updating for more than 5 minutes:

1. Check the cluster Arc resource bridge (az arcappliance show) is in a healthy state
2. Confirm the vSwitch name matches exactly (case-sensitive): Get-VMSwitch on a cluster node
3. Verify the VLAN ID does not conflict with an existing logical network on the cluster
4. Delete the failed resource and re-run: az stack-hci-vm network lnet delete --name <lnet-name> --resource-group <rg> --yes

---

Troubleshooting

Issue	Cause	Resolution
Logical network creation fails with InvalidParameter	vSwitch name mismatch (case-sensitive) or invalid VLAN ID	Verify vSwitch name exactly: Get-VMSwitch on a cluster node; ensure VLAN ID is within valid range (1-4094)
Logical network stuck in Updating state	Arc resource bridge processing delay or unhealthy	Check bridge status: az arcappliance show; if unhealthy, restart the bridge appliance VM on the cluster
VLAN traffic not flowing on the logical network	Physical switch trunk port missing the VLAN	Verify switch configuration allows the VLAN on all uplink ports; check Get-VMSwitch for correct teaming config
