Single LTM with multiple GTM domains
I am currently working on a Datacenter migration and we are re-IP'ing everything and rebuilding all the network appliances. I am working out the BEST, least impactful, way to migrate the GTM appliances to the new DC's. Here is the overall situation. Everything is the same version running 15.x.x with a mix of rSeries hardware running VE's and iSeries hardware also running VE's. Existing DC's: GTM Domain with two GTM's in different DC's Multiple LTM's all joined to the GTM New DC's: Two GTM's in different DC's, blank configuration Multiple LTM's all joined with the existing DC GTM's I know that I can add the new GTM's to the existing DC GTM domain, let them sync up, then update the NS records to migrate the DNS flows over to the new DC, but that also sync's over all the technical debt and limits my pre-testing abilities. I would like to setup a new GTM Domain in the new DC, build some automation for the WideIP / Pool creation, and manually review / rebuild all the necessary records in the new DC. My hangup is that this is ONLY possible if the LTM appliance can join multiple GTM domains. Can a single LTM appliance join multiple GTM domains and report status to multiple appliances? I don't have an easy way to build a test environment and build this out with VE's and validate so I am hoping for some input from the community.
Terraform AS3 code for GTM Only.
Hello All, I am really really suffering here :( Have been looking for GTM ONLY code in AS3 form, need a simple code hardcoded values will also work. I have seen documentation and couldn't see exact use case. We are doing POC for where VMs are direct;y added to GTM and NO LTM component are there. I can't post my LTM + GTM code as its in office. Would really appreciate any help and guidance here. Any simple code work snippet using only AS3 please.DNS/GTM health monitor big3d timeout because of alias config
Hello Everyone, I was testing some experimental config for DNS/GTM where the health monitor does not monitor the pool members but a specific IP address configured in the "alias" and it does not work as the error says bigd timeouts to report the state. For LTM http/https health monitors the "alias" option works but not for gtm/dns. I think I discovered a bug as this is rare use case to not monitor the pool members themselves. I have changed the ip to 1.1.1.1 just for the picture screenshot 😄 Also in the logs after gtm and big3d is enabled I see the logs below and too bad that F5 DNS does not have monitor debug like LTM to just enable a debug for a monitor and not the entire box. ----- Will not probe x.x.x.x:80 ( in DC /Common/niki-dc because will be done by other GTM (<unknown>:<unknown>) Unable to identify which gtm server represents the local device
cross platform migration issue
Hi, we want to migrate the config from iseries 4K to rseries 5k . The current software version on iseries is 13.x.. I tried to run bigip v15.x on rseries, then export the config from iseries and import it into rseries, but not successful, there were some errors. Can someone please advise how should I do to make the migration successful? Thanks in advance!

Good day, everyone! Within the LTM platform, if a Pool is configured with "Min 1 of" with multiple monitors, you can check the status per monitor via tmsh show ltm monitor <name>, or you can click the Pool member in the TMUI and it will show you the status of each monitor for that member. I cannot seem to locate a similar function on the GTM/BIG-IP DNS platform. We'd typically use this methodology when transitioning to a new type of monitor, where we can passively test connectivity without the potential for impact prior to removing the previous monitor. Does anyone have a way through tmsh or the TMUI where you can check an individual pool member's status against the multiple monitors configured for its pool? Thanks, all!why the gtm probing result is not shown on debug log?
hi ,we encounter some gtm wideip pool monitoring issue. then I tried to turn on the debug for gtm logging. The log captured for pool member status monitoring is shown as below only. There is no result about the probing, why? Can someone please advise on it? thanks in advance. debug gtmd[6034]: 011ae039:7: Check probing of IP:Port 10.50.62.252:8833 in DC /Common/DC-NY debug gtmd[6034]: 011ae03b:7: Will probe 10.50.62.252:8833 in DC /Common/DC-NYIs iQuery sent to each other among GTMs and LTMs? full mesh?
hi, we have 3 data centers and there are two LTM and one GTM at each data center. All GTM are configured in the same sync-group. And LTM are added to local GTM server list. For this setup, normally we shall see the iQuery are sent bidirectionally with full mesh, right? I saw one GTM A sent iQuery to GTM B, but no iquery from GTM B to GTM A, is it normal? please advise, thanks in advance!
