Hi,

Trying to set up two Ax 1030 in HA-mode (Active/standby)  
Config on AX1:  
-Standby#show running-config ha  
ha id 1 set-id 1  
ha group 1 priority 100  
ha interface ethernet 1  
ha preemption-enable  
ha conn-mirror ip 172.16.1.152  
!

1-Standby#show running-config interfaces ethernet 1  
interface ethernet 1  
ip address 172.16.1.151 255.255.255.0  
name “HA”  
!

Config on AX2:  
-Active#sho running-config ha  
ha id 2 set-id 1  
ha group 1 priority 200  
ha interface ethernet 1  
ha conn-mirror ip 172.16.1.151  
!  
-Active#show running-config interfaces ethernet 1  
interface ethernet 1  
ip address 172.16.1.152 255.255.255.0  
name “HA”  
!

Have also syncroniced the configuration in the webgui with success (i think..)  
Anyway, when I am doing changes to the configuration on the active node is will not summit the config to the standby node.

Should not this work flawless?

Thanks in advaced.

Hello,

Using standard HA you will still need to manually synchronize the configurations. If you want to have automatic config synchronization you will need to configure the AX for aVCS (virtual chassis system). The configuration is a bit more challenging but there is en example config in the config guide if you wish to try.

Hi,

The AX do not have support for active/passive chassis. My understanding was that it worked like netscreen nsrp protocoll.

Have enabled VCS with VRRP on the top. Works great 🙂

Thanks for you reply.
