OPT interfaces in HA not matching

[michmoor]

I have been running with a single 6100 without HA for at least 2 years and now i have secured a another 6100 so the plan is to stand up HighAvail.
The problem i am facing is that on the Master, i have interfaces/OPTs that do not line up with whats on the Backup

For example i have opt7,igc2.11 on the Master and on the Backup when i attempt to assign the interface i only see igc2.11 as opt5

HA Sync will not work if the interfaces do not line up exactly but i have no control over how the OPT interfaces are numbered. Any suggestions?

@michmoor I'd change all occurrence of opt5 to opt7 in the config file on the backup node directly using viconfig on the command line. Of course making sure that there is no existing opt7.

Or export the config of the backup node and edit it on your computer. And upload it to the backup node afterwards.

@patient0 spot on. That is working. Appreciate the assist !

@michmoor happy it worked.

I wasn't sure how it handles adding other interface(s) later. And gave it a go on testing pfSense CE.
If you ever add another interfaces (virtual, pppoe) it will end up as the lowest, free OPT. OPT5 in your case on the backup node.
