F5 in AZ
We are building F5 BIG-IP in Azure. Our long term intention is Active-Active or Active-Standby HA, but to kick start we are deploying a single standalone instance first. The F5 is not exposed to the internet directly. We have a Palo Alto firewall performing DNAT to convert the public IP to a private IP, and that private IP is the F5 VIP. We are using Azure basic Load Balancer to send traffic to F5. Our example external subnet is 10.1.1.0/24 and the IPs are configured as follows on the Azure NIC and F5. The Primary Self IP is 10.1.1.10, the first Secondary IP is 10.1.1.11 which is VIP for App1, and the second Secondary IP is 10.1.1.12 which is VIP for App2 and follows. My questions are as follows. First, in the ALB backend pool, should we use the Primary Self IP 10.1.1.10 or the Secondary VIP IPs 10.1.1.11 and 10.1.1.12? If we use Secondary IPs, do we need a separate ALB for each VIP? We have seen some older videos suggesting Secondary IPs should be used in the backend pool but we want to confirm the correct approach. Second, when we expand to HA in the future by adding a second F5 device, can both devices be configured with the same VIP IPs such as 10.1.1.11 and 10.1.1.12? And since Azure does not support floating IPs moving between VMs, we understand ALB health probes handle failover, so in that case should the ALB backend pool contain the Primary Self IPs of both devices? Please advise on the correct design for both standalone and HA scenarios.The State Of HTTP/2 Full Proxy With F5 LTM
In this article, I will attempt to summarize the known challenges of an HTTP/2 full proxy setup, point out possible solutions, and document known bugs and incompatibilities. Most major browsers had added HTTP/2 support by the end of 2015. However, I hardly ever see F5 LTM setups with HTTP/2 full proxy configured.
Pre & Post validation of F5 configuration
Hi, I am planning to do a F5 vCMP Guest upgrade, just want to know before upgrade as part of pre validation of VS/Pool (Online & Offline status) & also a snap shot of the current configuration & after upgrade again to do post validation of VS/Pool (online/Offline Status) & to take a post upgrade snap shot for comparison to pre upgradation snapshot to make sure all are as per the same before & after the upgrade.F5 Container Ingress Services (CIS) deployment using Cilium CNI and static routes
F5 Container Ingress Services (CIS) supports static route configuration to enable direct routing from F5 BIG-IP to Kubernetes/OpenShift Pods as an alternative to VXLAN tunnels. Static routes are enabled in the F5 CIS CLI/Helm yaml manifest using the argument --static-routing-mode=true. In this article, we will use Cilium as the Container Network Interface (CNI) and configure static routes for an NGINX deployment For initial configuration of the BIG-IP, including AS3 installation, please see https://clouddocs.f5.com/products/extensions/f5-appsvcs-extension/latest/userguide/installation.html and https://clouddocs.f5.com/containers/latest/userguide/kubernetes/#cis-installation The first step is to install Cilium CNI using the steps below on Linux host: CILIUM_CLI_VERSION=$(curl -s https://raw.githubusercontent.com/cilium/cilium-cli/main/stable.txt) CLI_ARCH=amd64 if [ "$(uname -m)" = "aarch64" ]; then CLI_ARCH=arm64; fi curl -L --fail --remote-name-all https://github.com/cilium/cilium-cli/releases/download/${CILIUM_CLI_VERSION}/cilium-linux-${CLI_ARCH}.tar.gz{,.sha256sum} sha256sum --check cilium-linux-${CLI_ARCH}.tar.gz.sha256sum sudo tar xzvfC cilium-linux-${CLI_ARCH}.tar.gz /usr/local/bin rm cilium-linux-${CLI_ARCH}.tar.gz{,.sha256sum} cilium install --version 1.18.5 cilium status cilium status --wait root@ciliumk8s-ubuntu-server:~# cilium status --wait /¯¯\ /¯¯\__/¯¯\ Cilium: OK \__/¯¯\__/ Operator: OK /¯¯\__/¯¯\ Envoy DaemonSet: OK \__/¯¯\__/ Hubble Relay: disabled \__/ ClusterMesh: disabled DaemonSet cilium Desired: 1, Ready: 1/1, Available: 1/1 DaemonSet cilium-envoy Desired: 1, Ready: 1/1, Available: 1/1 Deployment cilium-operator Desired: 1, Ready: 1/1, Available: 1/1 Containers: cilium Running: 1 cilium-envoy Running: 1 cilium-operator Running: 1 clustermesh-apiserver hubble-relay Cluster Pods: 6/6 managed by Cilium Helm chart version: 1.18.3 Image versions cilium quay.io/cilium/cilium:v1.18.3@sha256:5649db451c88d928ea585514746d50d91e6210801b300c897283ea319d68de15: 1 cilium-envoy quay.io/cilium/cilium-envoy:v1.34.10-1761014632-c360e8557eb41011dfb5210f8fb53fed6c0b3222@sha256:ca76eb4e9812d114c7f43215a742c00b8bf41200992af0d21b5561d46156fd15: 1 cilium-operator quay.io/cilium/operator-generic:v1.18.3@sha256:b5a0138e1a38e4437c5215257ff4e35373619501f4877dbaf92c89ecfad81797: 1 cilium connectivity test root@ciliumk8s-ubuntu-server:~# cilium connectivity test ℹ️ Monitor aggregation detected, will skip some flow validation steps ✨ [default] Creating namespace cilium-test-1 for connectivity check... ✨ [default] Deploying echo-same-node service... ✨ [default] Deploying DNS test server configmap... ✨ [default] Deploying same-node deployment... ✨ [default] Deploying client deployment... ✨ [default] Deploying client2 deployment... ✨ [default] Deploying ccnp deployment... ⌛ [default] Waiting for deployment cilium-test-1/client to become ready... ⌛ [default] Waiting for deployment cilium-test-1/client2 to become ready... ⌛ [default] Waiting for deployment cilium-test-1/echo-same-node to become ready... ⌛ [default] Waiting for deployment cilium-test-ccnp1/client-ccnp to become ready... ⌛ [default] Waiting for deployment cilium-test-ccnp2/client-ccnp to become ready... ⌛ [default] Waiting for pod cilium-test-1/client-645b68dcf7-s5mdb to reach DNS server on cilium-test-1/echo-same-node-f5b8d454c-qkgq9 pod... ⌛ [default] Waiting for pod cilium-test-1/client2-66475877c6-cw7f5 to reach DNS server on cilium-test-1/echo-same-node-f5b8d454c-qkgq9 pod... ⌛ [default] Waiting for pod cilium-test-1/client-645b68dcf7-s5mdb to reach default/kubernetes service... ⌛ [default] Waiting for pod cilium-test-1/client2-66475877c6-cw7f5 to reach default/kubernetes service... ⌛ [default] Waiting for Service cilium-test-1/echo-same-node to become ready... ⌛ [default] Waiting for Service cilium-test-1/echo-same-node to be synchronized by Cilium pod kube-system/cilium-lxjxf ⌛ [default] Waiting for NodePort 10.69.12.2:32046 (cilium-test-1/echo-same-node) to become ready... 🔭 Enabling Hubble telescope... ⚠️ Unable to contact Hubble Relay, disabling Hubble telescope and flow validation: rpc error: code = Unavailable desc = connection error: desc = "transport: Error while dialing: dial tcp 127.0.0.1:4245: connect: connection refused" ℹ️ Expose Relay locally with: cilium hubble enable cilium hubble port-forward& ℹ️ Cilium version: 1.18.3 🏃[cilium-test-1] Running 126 tests ...

User Configuration Set (UCS) archives are central to F5 BIG-IP configuration management, supporting backup, system recovery, and platform migrations. In production environments, UCS restores are often performed during maintenance windows or critical recovery scenarios—making reliability and predictability essential. While the UCS mechanism is robust, restore operations can fail for a variety of reasons, ranging from encryption dependencies and platform constraints to feature provisioning and licensing differences. Many of these failures are not random; they follow well-defined patterns that can be identified and mitigated with the right preparation. This article consolidates commonly encountered UCS load failure scenarios, explains their underlying causes, and outlines recommended resolution strategies based on publicly documented behavior, operational best practices, and official F5 knowledge base guidance. The goal is to help administrators recognize issues quickly, reduce trial-and-error during restores, and plan UCS operations with greater confidence—especially during platform transitions such as VE to rSeries or VELOS. Pre-Flight Validation Checklist (VE → rSeries / VELOS) Master Key and Encryption State tmsh list sys crypto master-key Ensure the target system’s master key state is compatible with the source system when restoring encrypted objects. Platform Feature Requirements Enable required features such as network-failover prior to restore. Provisioned Modules Confirm all referenced modules are licensed and provisioned. ASM / Advanced WAF Considerations Validate ASM MySQL database health. Consider importing ASM policies separately if issues arise. Licensing and Resource Alignment Ensure licensed core counts align with platform resources. Note: Issues may surface after reboot. Active Configuration Operations tmsh show sys mcp-state Management and Routing Conflicts Check for duplicate management routes. Maintenance Window Awareness Perform restores on standby units during maintenance windows. Fast Triage Guide Logs to Check /var/log/ltm /var/log/restjavad.0.log /var/log/asm Review error keywords such as: master key, encrypted, license, MySQL, duplicate, failover Key Failure Scenarios Master Key or Encryption Mismatch Resolution: Rekey or recreate encrypted objects. Corrupted or Incomplete UCS File Resolution: Use a known good backup. Encrypted UCS Without Passphrase Resolution: Provide correct passphrase. Platform or Version Mismatch Resolution: Enable required features or adjust config. Simultaneous Configuration Actions Resolution: Wait for other tasks to complete. ASM / MySQL Issues Resolution: Import ASM separately or repair database. FIPS Key / Certificate Issues Resolution: Migrate FIPS keys first. Resource or Licensing Mismatch Resolution: Align licensing and resources. Configuration Conflicts Resolution: Remove conflicting objects. Unexpected Failover or Service Restart Resolution: Restore during maintenance windows. VIPRION Hardware Swap Considerations (Blade / Chassis Transitions) When restoring UCS files during VIPRION hardware swaps (for example, 4340 → 4450 or 4460 blades), additional manual validation is required due to chassis-level and blade-specific configuration differences. Files Requiring Manual Review and Adjustment bigip_emergency.conf .cluster.conf bigip.conf bigip_base.conf Post-Modification Requirement After making any manual edits to configuration files: tmsh load sys config Conclusion Proper UCS restore preparation reduces downtime and operational risk, particularly during platform migrations, hardware swaps, or disaster recovery scenarios. Most UCS load failures are predictable and preventable when encryption state, licensing, platform features, and configuration dependencies are validated upfront. Treat UCS restores as controlled change operations, not simple file imports, and you dramatically improve recovery outcomes across BIG-IP platforms.Accelerate Application Deployment on Google Cloud with F5 NGINXaaS
Introduction In the push for cloud-native agility, infrastructure teams often face a crossroads: settle for basic, "good enough" load balancing, or take on the heavy lifting of manually managing complex, high-performance proxies.
