I'm familiar with admin sections for Device Management > Devices , Device Groups .. but I'm not seeing how to configure FIP ... perhaps it's there but I'm not seeing it

you just assign non-local traffic group (e.g. traffic-group-1) to floating object (e.g. selfip, virtual server ip).

sorry to be dense but i don't see a virtual-server with ip corresponding to the fip for our traffic-group ... our traffic-group has two devices with ips 192.168.220.220,221 ... by inspection, fip 192.168.220.222 directs traffic to active device .. but there is no virtual-server with ip 192.168.220.222 ... i'm just not seeing where fip is configured

these are my selfip and virtual server address settings. for the selfip, 172.28.24.12 and 200.200.200.12 are non-floating and 172.28.24.14 and 200.200.200.14 are floating. for the virtual server address, of course, it is floating.

Hi Baltostar,

on CLI you can check for floating self IPs with the following command (single-line output, filters "floating enabled" and prints strings #3 [name] and #6 [address/mask]):

tmsh list net self one-line | awk '/floating.enabled/ {print $3, $6}'

In WebUI the floating self IPs should be listed in Failover Objects of your traffic-group-1 or other traffic-groups you have added. Of course they will show up as well in the list of self IPs not belonging to "traffic-group-local-only" as in nitass screenshot.

To create a floating self IP requires to already have a non-floating self IP in the related VLAN.

tmsh create net self self_float_175 address 10.131.131.176/24 vlan vlan_prod_131 allow-service none traffic-group traffic-group-1

The example above creates a new floating self IP in traffic-group-1. If you don´t set the traffic-group parameter it will be a non-floating self IP and assigned to the traffic-group-local-only.

Thanks, Stephan
