Other posts about EVPN/VXLAN in Proxmox VE: Let’s continue inspecting ARP and ND suppression features when using EVPN in Proxmox Virtual Environment (PVE). Initial setup I still have the EVPN1 VNet (VNI = 5001) configured in the PVE cluster (from the previous post), with no IP subnet configured for the VNet. VM1 is on the […]
Other posts about EVPN/VXLAN in Proxmox VE: In the earlier post Configuring VXLAN in Proxmox VE I showed L2 VXLAN data plane implementation on a Proxmox Virtual Environment (PVE) cluster. There was no special control plane for MAC learning so the PVE nodes learned the locations of MAC addresses just on the go, flooding the […]
On a HPE Aruba Networking 6300M switch someone had changed the outbound BGP policy, but apparently the platform did not trigger outbound BGP updates automatically in that case, so I was looking for a soft outbound reset functionality. Tested with AOS-CX version FL.10.13.1090: myarubaswitch# clear bgp vrf MY_VRF ipv4 unicast 10.10.10.10 soft outInvalid input: outmyarubaswitch# […]
Other posts about EVPN/VXLAN in Proxmox VE: About VXLAN From Wikipedia: Virtual eXtensible LAN (VXLAN) is a network virtualization technology that uses a VLAN-like encapsulation technique to encapsulate OSI layer 2 Ethernet frames within layer 4 UDP datagrams, using 4789 as the default IANA-assigned destination UDP port number, although many implementations that predate the IANA […]
When launching EC2 instances on AWS, you might need to install and run the CloudFormation helper scripts (https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/releasehistory-aws-cfn-bootstrap.html). However, since February 2026, as of the latest CloudFormation helper scripts version 2.0-38 (released on 2025-12-04), installing them works fine, but running for example cfn-init causes an error: ModuleNotFoundError: No module named ‘pkg_resources’ The reason is this […]
What does this mean in the HPE Networking AOS-CX REST API response when getting the MAC address tables from a switch: GET /rest/v10.08/system/vlans/*/macs/*,*… ‘dynamic,11:22:33:44:55:66’: { ‘aged_on_subsystems’: {}, ‘attributes’: {‘local_move_disable’: False}, ‘denied’: False, ‘derived_entry_src’: ‘none’, ‘desired_port’: { ‘1/1/49’: ‘/rest/v10.08/system/interfaces/1%2F1%2F49’ }, ‘from’: ‘dynamic’, ‘inactivity_timeout’: 300, ‘mac_addr’: ’11:22:33:44:55:66′, ‘network_infra_mac’: False, ‘never_ageout’: False, ‘port’: None, ‘selected’: True },… Why […]
I, for one, was quite excited when IKEA announced new Matter-based affordable smart home devices in 2025. I finally got to buy some of them and I was going to add them in my existing Home Assistant system. Specifically, for this test, I bought: They are talking with each other using Matter over Thread, the […]
Over the years I’ve done quite much software, integration and business process development using NetBox. Still, when developing code and configurations in various contexts, I’m sometimes unsure about the object or model syntax I need to follow. Thus, this post. Update on 2026-01-27: There is NetBox PR #21209 currently in the progress to unify the […]
In F5 BIG-IP devices there is iControl REST API for interfacing with the devices programmatically. In this post I’ll briefly describe the basics of using the API in Python. I’ll be using BIG-IP version 17.1 here with a separately created non-administrator user account. For starters I’ll use a Python virtual environment to contain the separately-installed […]
I’ve recently used various kinds of message queues when building various apps that have needs to communicate with other parts of the app. For remote use, when the messaging parties are not on the same host, I’ve mostly used Amazon SQS, the Simple Queue Service. When using the SQS ReceiveMessage API call you can select […]
