Configure HA a/p on Thunder1040

Product Discussions ADC - Application Delivery

Good afternoon,
I’m new in the forum. I have 2 Thunder1040-F devices with firmware 5.2.1-p3, build 70, we want to configure HA in active/passive mode, what would be the procedure to do it. and that the synchronization is done automatically from the primary to the secondary
Thank you

  1. Welcome! There are two pieces to configure which work hand in hand to accomplish your goals:
    VRRP - this provides HA data plane redundancy
  2. VCS - this provides automatic config sync between the devices

I have attached the guides for both of these, but they’re also available on the A10 Support Portal. VRRP is configured first followed by VCS. I have also attached a couple example configs for how the final config will look. Be sure to check the configuration steps on the VCS guide.

Good night.
Thank you for your support, I have a concern, after having configured the interfaces, the static route, hostname, I must configure the vrrp as mentioned in the commands you sent me:
vrrp-a common
 device-id 1
 set-id 1
 enable
!
device-context 1
 vcs enable
!
device-context 2
 vcs enable
!
vcs device 1
 priority 140
 interfaces management
 enable
!
vcs device 2
 priority 100
 interfaces management
 enable
vrrp-a vrid 0
 device-context 1
  blade-parameters
   priority 150
 device-context 2
  blade-parameters
   priority 140
!
vrrp-a interface ethernet 1/4
!
vrrp-a interface ethernet 2/4
!
vrrp-a preferred-session-sync-port ethernet 1/4
!
vrrp-a preferred-session-sync-port ethernet 2/4
but in the document something called floating IP appears, it is mandatory to configure that parameter? if so how should I configure it because I don’t understand that concept well
Thanks

The floating IP’s are configured under the VRRP VRID. Here is an example:

vrrp-a vrid 0 
  floating-ip 10.1.1.100 
  floating-ip 10.2.1.116 
  floating-ip 10.3.1.84 
  device-context 1
    blade-parameters
      priority 150
  device-context 2
    blade-parameters
      priority 140

Floating IP’s are not required, but they can be useful for failover depending on your network routing configuration. The Active device in VRRP will advertise the floating IP’s, and they can be used as next hop in routes.

Hello,
Thank you for the support you have given me, for some reason the configurations are not synchronizing between the 2 devices, I created a new server on one device but it was not replicated, what parameters should you review for this.
Thanks

Sounds like VCS may not be communicating or running properly. You can check the status of VCS from the CLI with “show vcs summary”. Here’s an example of a functional VCS output. Did you perform a “vcs reload” after configuring vcs?
