AWS PAN-OS 11 Interfaces never become active

L1 Bithead

I'm trying to bring up a new PAN-OS 11.1 instances in AWS, installed from aws-marketplace/PA-VM-AWS-11.1.0-f1260463-68e1-4bfb-bf2e-075c2664c1d7. I am able to reach the management IP address, both SSH and the web UI are working. However the two intended network interfaces never appear in "show interface all" nor in the UI Network > Interfaces > Ethernet.

 

I created three subnets within the VPC and three Elastic Network Interfaces, which are attached to the EC2 instance.

  • The eni used for the management interface and for the WAN have Elastic IP addresses attached.
  • The subnets for MGMT and LAN have a routing table with a default route pointing to the ENI.
  • The subnet for the WAN has a routing table with a default route pointing to the Internet Gateway for the VPC.

 

From the AWS EC2 instance tab:

Interface ID
Description
IPv4 Prefixes
IPv6 Prefixes
Public IPv4 address
Private IPv4 address
Attachment status
VPC ID
Subnet ID
Source / destination check
Security groups
Interface type
eni-09c...
MGMT 52.25.x.y 10.0.6.71 attached
vpc-0d2...b90
subnet-036...
enabled
sg-093...
Elastic network interface
eni-062...
WAN 35.82.x.y 10.0.64.130 attached
vpc-0d2...b90
subnet-025...
disabled
sg-083...
Elastic network interface
eni-06b...
LAN 10.0.137.103 attached
vpc-0d2...b90
subnet-03c...
disabled
sg-07f...
Elastic network interface

In "show system state" I see the MAC addresses of the Elastic Network Interfaces I expect. sys.s1.p1.hwaddr is the MAC address of eni-062... intended for the WAN, and sys.s1.p2.hwaddr is the MAC address of eni-06b... intended for the LAN.

However no interfaces appear in "show interface all" and the Web UI never shows their status as green.

admin@PA-VM> show interface all

total configured hardware interfaces: 0

name id speed/duplex/state mac address
--------------------------------------------------------------------------------

aggregation groups: 0


total configured logical interfaces: 0

name id vsys zone forwarding tag address
------------------- ----- ---- ---------------- ------------------------ ------ ------------------

In other posts I've read that this means the interface is not configured. I set the interface type of the first two Ethernet interfaces to Layer3, created a management profile which allows ICMP ping, and set their IP address to use DHCP.

 

The ENI which I'm intending as the WAN interface has a public IPv4 Elastic IP address associated with it, which I would expect means AWS should respond to a DHCP request for that interface at least.

I've rebooted the EC2 instance multiple times, including going all the way to Stopping the instance and then Starting it again to ensure any new device tree will be properly handled at boot.

 

I'm running out of ideas of what to try. What else could be preventing PAN from seeing these links as configured and active?
