I have Flex Appliances 5250 and when I check ifconfig from support >> shell there are network interface docker0, mgmt0, host0 etc..
And by default when the appliance not configure IP Address on docker0 192.168.229.233 but that IP can not be reach when I direct connect my laptop to the interface eth0/nic1... I put 192.168.229.234/24 on my laptop.
When I'm finish doing initial configuration set into interface mgmt0 not docker0.
My Question is : What is the function of the docker0, mgmt0, host0, nic0 network interface ? Can Somebody explain..
And Can I access to 192.168.229.233 ?
Attached the capture.

host0: This represents the physical ethernet port (copper - nearest to the IPMI) on 5250 appliance.
mgmt0: This is bonded interface covering host0 (Yes, eventhough it's single interface only, it's configured as balanced-alb by default). When the appliance configured (setup configure-network and setup configure-console), it allows you to connect to node (via ssh & hostadmin user) and Flex Console (via https & admin user).
nic0-nicX: These are the physical ethernet ports used for data traffic, including backup/restore/replicaton. These are associated with the intances running on the Flex Appliance.
docker0: Flex uses micro-services architecture based on docker and it's there. That IP address is internal to docker and not accessible.
Hope it helps.
