GTM - Monitor bigip from gtmd: no reply from big3d

I have two pairs of GTM's and LTM's in HA mode.

 

 

GTM A/B GTM C/D

 

 

LTM A/B LTM A/B

 

 

The GTM HA pair's have a self ip each, and a floating ip. I have the listener set to the floating ip.

 

 

The virtual servers in the GTM are showing some as down, even though the LTM says they are up. I get the error Monitor bigip from gtmd: no reply from big3d.

 

 

Do I have my listener setup correctly? Should it be the floating ip in the pair? Its set to UDP also, on all vlan's.

 

 

Thanks,

 

Nick
  • Did you make sure you copied the keys so that the bigip and GTM can communicate. I am assuming that you add the LTM to the GTM

     

  • Yes, and most of the virtual servers on the GTM are showing as green, but only a handful are getting the error. Even though they are on the same LTM.
  • I would add the listening on the self addresses and see if that makes a difference.

     

     

     

  • I've seen this when all the server selfs are not routable with the GTMs. Example setup that eliminated this problem:

     

     

    GTM1/2 in DC1 needs to be able to route/communicate with GTM1/2 in DC2 & LTM1/2 in DC1 & DC2 on iquery port (I also allowed ssh)
