F5 Ltm Pool members http down
F5 Pool monitors http traffic and node Offline (Enabled) - Pool member has been marked down by a monitor. The same problem has been encoutered before. Do you have an idee? Many thx.
Dears, Finally I found the error I have done. The vlan's were tagged and normaly they shouldn't as I have done this in lab with VMWare workstation pro. I just modified vlan's from tagged to untagged. Thanks for all of you for your help.

From the bash, you can try to use curl or wget to simulate the monitor check and observe the output form the pool member to troubleshoot further.

Hi,
In order to investigate, you can enable "Monitor Logging" for that, go to:
Local Traffic ›› Pools : Pool Lis >> then click on your poolmemeber then check Monito Logging.
The system stores logs in /var/log/monitors/, which are regularly rotated and compressed.
you can too check your application from F5 using CLI when the problem occur:

Make sure that the node healthcheck is also succesfull. Most of the time this is an icmp check to the IP adress of the poolmember.
If this succeeds you can try to perform a curl from bash.

Dears, Many thanks for your answers. Is seems that a route is missing I can't ping the webservers (nodes) 10.2.0.11 and 10.2.0.33. Is it normal? see the log Besides when I do a telnet 10.2.0.11 80 I have the following answer "No route to host". In the configuration of BigIP I only declared the external route. Is it enough? thx

Hi,
Verify the routing using tmsh show /net route.
Then can you add a static route just for testing?
10.2.0.11 to GW...
