Self-ip Not pingable

Hi All, With VMWARE ESX, I have 2 F5 VMs. In both F5 VM's internal and HA interfaces respond to self ping and also from each other, but having issues with ping with external interface self-ips. External self ips ping themselves fine. However, they are not able to ping the other F5 device. In this setup, we have a dedicated interface for the external vlan. Any thoughts on why this can be? I have deleted and recreated the vlan, self ips; I have tried tagged and untagged, I have checked the port lockdown is allowed all, I have requested the VM interface to be reinitialised, has not helped. Running 13.1.0. There is no other config other than the interface initialisation and DNS/NTP server ip address. Any thoughts? I don't think its a F5 issue?

Thanks, Vidhya

Agreed with the previous response. Sounds like a VLAN issue.

  • If there is a default gateway or IP on the ESX Server on the External vlan, try to ping that from the F5's.
  • Try to add other devices to the same external vlan and see if they can ping each other.
  • On the F5 VM control panel, make sure the right interface is actually connected to the ESX vlan. Bear in mind that iv the VM has 4 interfaces, the first one is MGMT, the second one should be 1.1, third one 1.2, and so on.
  • The following has worked for me a couple of times: have each F5 start pinging its peer and then under the F5 VM's settings, check and uncheck a couple of times the "connected" tickbox, this should cause them to start sending gratuitous ARP's Image Text

Many Thanks to everyone that responded. It is indeed a VMWare issue.

Hi Vidhya203,

I could not understand your problem "External self ips ping themselves fine. However, they are not able to ping the other F5 device." What do you mean by the other F5 device?

Do you have an HApair that wants to reach another F5?

Could you please clarify your problem in detail?

This seems a VLAN problem. Can you double-check that this external VLAN is extended from the external switch all the way to the port-group of the VEs. And can you also double check if there routes for this ping to happen?
