Hi Team, I'm planning to deploy openstack over a blade server. The blade server have switch ports that connected to tor switch. My questions is how do openstack detect which port on the server switch is belongs to which server. I have read openstack network configuration and seems from the configuration file the nic name is enter for example as p1p1 or p2p1 (slot2 port1)... I couldn't understand how they get the name like that...i have check on my server it didn't show something like that (p1p1/p2p1) for the nic/port name... I'm not sure the exact name that i should enter in the nic configuration file ...so I'm stuck right now... Please advise me. Thank you for helping.

Which documentation did you read? Please be aware that the instructions on docs.openstack.org don't know your particular interface names. You have to replace the examples in the documentation with the names on your servers.

Can I get the each interface name from ifconfig? and use the name I got for config file for my overcloud...? Is this the correct way...?

it would help me help you if you told me which web page or other source refers to p1p1.

Yes you can list your server's (not the switch's) ports with ifconfig, although this tool is often not installed. Better use ip a.

I strongly recommend learning Linux networking before installing OpenStack.
