Add and change sync network in VSX

[slowfood27]

Q1: How can I modify the netmask of an existing sync network in a VSX-1 Cluster?
Q2:How can I add a 2nd sync network?

[slowfood27]

Found it. It's in the GUI under topology.
Tested in the LAB with Gaia VSX R75.40VS.
The second sync does not work in my config. I also re-bootet the whole cluster after having added the 2nd sync interface. Without re-booting, it does NOT show up in the SmartView Monitor, with a re-boot, it is beeing displayed in the SmartView Monitor.
tcpdumping shows sync traffic on both sync interfaces (I used physical interfaces "Sync" and "Lan1").
But when I disconnect the 1st sync crosssover Cable, the VSX cluster shows:


Idefix:0> cphaprob state

Re-attaching the 1st sync cable brings ths cluster back to normal operation.
Has anyone ever sucessfully tested such a sync failover?

Did you check the documentation and release notes?

I remember that for R67 VSX a second sync was not supported, even if it was possible to define it, and that fact was mentioned in release notes or known limitations.
