How to enable/disable Azure Accelerated Networking and Validate

• Azure Accelerated Networking may enabled/disabled either via Azure GUI Portal or CLI.
• Post PAN-OS 9.0, AN is enabled by default.
• This document will help with steps to enable or disable this configuration. Also, how to validate if Accelerated Networking is enabled.

• Platform: PA-VM on Azure
• PAN-OS/Plugin Version: 9.0. or above
• Deployment: Existing/New

1. Click on the name of the virtual machine that you want to examine.
2. In the navigation panel, under Settings, select Networking to access the networking configuration settings available for the selected Azure VM.
3. In the network interface information, next to the Accelerated networking label, the portal displays either Disabled or Enabled for the accelerated networking status.
4. Select the NIC, enable or disable this setting under 'Overview' tab. 

Disabling Accelerating Networking:

 

1. Open Azure CloudShell.
2. In the CloudShell, select PowerShell from the drop-down menu.
3. Stop/deallocate the VM:

az vm deallocate --resource-group <resource_group_name> --name <name_of_VM>

4. Enter the following commands. Replace your network interface card and resource group name:

az network nic update --name <name_of_NIC> --resource-group <resource_group_name> --accelerated-networking <true/false>

5. Restart the VM:

az vm start --resource-group <resource_group_name> --name <name_of_VM>

1. In Techsupport file, check for logs below in mp\brdagent.log file:

interfaces are panos_eth2
interfaces are panos_eth1

2. On PAN-CLI, run following command:

> debug show vm-series interfaces all

Interface_name       Base-OS_port       Base-OS_MAC             PCI-ID         Driver     Acc-Netw
 mgt                     eth0          00:22:48:03:b6:ca                       hv_netvsc
 Ethernet1/1             eth1          00:22:48:03:b6:fc                      net_failsafe     ON
 Ethernet1/2             eth2          00:22:48:03:b9:69                      net_failsafe     ON 

Note1: Accelerated Networking is not supported on Management Interface (eth0) 
Note2: The VM may need to be powered off before the changes, So plan accordingly.
