About vlangroup traffic
Hello Expert, I’ve recently been trying out VLAN groups in a test environment. This is my environment. I’ve found that on the F5, there’s no need to configure any Virtual Servers; client(1.1.1.10) can connect successfully to Server:443(1.1.1.20). I set up an ForwardingL2-type virtual server, but no traffic is through the Virtual Server; instead, it goes through the VLAN group. Why isn’t the traffic being routed through the VS?
iRule Developer Tools
Hi All, I've made a set of developer tools for Tcl including iRules, https://github.com/bitwisecook/tcl-lsp This includes LSP server Editor integrations for VSCode, Sublime Text, Zed, Jetbrains, Helix, neovim, emacs and more (though I've only really hammered on vscode there) MCP server Claude skills cli tool Semantic token highlighting Hover docs Format string interpreters AI tools for creating, explaing, validating, documenting, diagramming iRules and Tcl full optimising compiler chain with 26 optimiser passes 27 iRule specific diagnostics and optimisations Security warnings through taint tracking (use of user input tracked through the code) Shimmer detection with inline type hints (know when a variable type is being reinterpreted) Code formatting Code minification Compiler explorer to look at how your code is interpreted A full iRule testing framework and more. This is only based on publicly available information and my memory, though I have deployed enough iRules. This is the tool I always wanted. I could do with help expanding and improving the profile -> event / command maps, and the iRule event graph, and with generally finding bugs, so please, open issues. I will be away on holiday for a couple of weeks so please bear in mind I may take a little time to get back to you. cheers, Jim 🇬🇧🇦🇺Running bigip to terraform resources
Hi, Posting here in the hopes someone finds this useful. This is not a product, it's a small open source tool that I've made to help manage our BigIPs. TL;DR: Running BigIP to Terraform resources: https://github.com/schibsted/bigip-to-terraform We recently started speaking about managing our BigIP in a more DevOpsy way at work. We have been using the web GUI most of the time and recently it has become more and more tricky to do transformations on the config text file to do large scale changes. We use terraform for AWS and some other things and I've not used it much myself so I thought I'd give terraform for BigIP a go. After looking at the docs and comparing with our running config and speaking to some different colleagues I found I wanted to see a terraform representation of our running config to see how new resources could be configured. So I wrote a script to dump our running config to terraform resources. It uses the python API to extract VIPs, pools and attendant nodes, writes a skeleton resource file and then "terraform import"s each resource. After that it uses "terraform show" with some light processing to generate a complete and valid terraform .tf file for all the resources found. There is one specific bug in the BigIP plugin to terraform (see the "issues" on github) that stops me from getting a complete automatic extract in our environment. And also for our full configuration (once I've removed the VIP resources that causes problems) "terraform plan" takes between 15 and 25 minutes. So I made a option to extract just VIPs matching a string or RE pattern, as well as their attendant pools and nodes. I've been able to "terraform apply" these back to a BigIP. The README file is quite complete, basically do `./runner` to get it all or `./runner -v 'pattern'` for a substring match in the VIP name, full path or IP number. This is not a migration tool since it does not extract or handle iRules, policies and such at all, they have to exist in the target environment already.
What is the best practice for migrating from iseries to rseries?
hi ,we plan to migrate to new r-series F5 (v15.1.x) from i-series legacy appliance v13.x.x. We will create the same vlans and IP address config, but the physical interfaces will be different. The new r-series appliance is already licensed. What is the best practice for this migration? option1: import the whole UCS file to new r-series appliance. after importing the ucs to new appliance, what are the next steps to complete the whole migration? option2: copy the config for every module, for example to copy ltm config first, then gtm, final AFW ...... can someone please advise, thanks in advance!
Cisco TACACS+ Config on ISE LTM Pair
I'm trying to add TACACS+ configuration to my ISE LTMs (v17.1.3). We use Active Directory for authentication. The problem is when I try to create the profile, the "type" dropdown does not show "TACACS+". APM is not provisioned either, not if that is needed. I provisioned it on our lab, but no help.
MAC users unable to access Internet when on Netskope
Hi Team, We recently upgraded our F5 APM Clients from 7245 to 7261 . Post that some users are unable to access generic Internet websites ( which are not tunneled ) like google, Github and much more. They just get the error as connection closed in browser. Anyone here faced the same issue and if yes any suggestions. Some Difference which we noticed were that some Non working users had Netskope installed in their system
Illegal Request in Learning Suggestion for 200 OK response
Dears, I want to know the reason why this suggestion is showing an illegal request status even though response code is 200 OK. Is it because multiple violations triggered? The policy is in transparent mode and I am just verifying the suggestions. Can someone please provide an expert advise?Migration from i5800 to r5800
Hi, Request to help me migration plan step by step from i5800 to r5800. In our production we are using i5800 hardware box with Active and standby HA link with version 17.1.2 and running both LTM and GTM. The hardware i5800 is going to end of support we are planning to migrate to hardware r5800. I request to help me step by step plan without any production impact and also help for the plan like tenant to tenant moving to new hardware to test and move rest of the configuration.Please let me know if any more information is required. Thanks in advance!SFP Port LEDs Blinking Yellow
Hi I upgraded the F5 OS to version 1.8 and the tenant software to 17.5.1.3. The upgrade went smoothly and both the Active and Standby devices successfully handled traffic after the upgrade. However I have noticed that the SFP port LEDs on both the Primary and Secondary devices are blinking yellow. Both devices appear to be operating normally but I would like to confirm whether this is expected behavior Could the yellow blinking indicate a speed mismatch or should the LEDs be green under normal conditionsHow are memory and disk allocated to different modules on bigip appliance?
hi, when doing "Resource Provisioning", the memory and disk space are auto allocated to LTM and ASM are shown as below. The amount of Memory and disk is minimum requirement, right? When a huge number of virtual server will be created later, will appliance auto allocate more spare memory and disk to the module? And what is he management module responsible for? Is it responsible for packet forwarding? should we set "Provisioning" to "Medium" or "Large" if the throughput is larger than 1Gbps? Can someone please advise? thanks in advance!
