3CX Debian 10 SBC Cluster

[mr412]

Hi!

I have a question with the floating IP. I have configured 2 SBC:

SBC 1
eth0:0: 10.xx.xx.101

SBC2
eth0:0: 10.xx.xx.102

on both I also have eth0:1 (floating ip)
10.xx.xx.100

but at the selection for the SBC HA service is empty. an interface selection works only without alias.

instead of:
eth0:0: 10.xx.xx.101
eth0:1: 10.xx.xx.100

what am i doing wrong here?

SBC is not supported yet on Debian 10, only debian 9

Have you followed these steps - https://www.3cx.com/docs/sbc-high-availability-cluster/

 

[mr412]

that was not the question (https://www.3cx.com/docs/installing-pbx-raspberry-pi/)

Enter an unallocated LAN address to serve as the floating IP for the clustered SBC service running on both nodes. SBC 1 and SBC 2 must both be configured with this IP.

the question is much more, is an alias enough (eth0:1) or do i have to set up a dummy interface for the floating ip?

Hi @mr412 ,
Have you tried following this guide?
https://www.3cx.com/docs/sbc-high-availability-cluster/

Generally, you need to configure a static IP for SBC A and SBC B.
The Floating IP you don't need to actually configure on the devices, just follow the on-screen instructions.

When it asks you for the Floating IP, input it.
All you need to make sure is that the IP you use as the Floating one, is not assigned accidentally by your DHCP to some other device on the network.

If you do everything correctly, if you run the "crm_mon" command, you should see both SBC IPs, and in the Management Console in the SBC "General" tab (you see the SBCs in the "SIP Trunks" node), you should see the Floating IP there.
