Brocade General Questions: Fabric Port Name vs Permanent Port Name

Hi,

I am trying to figure out which is the WWPN for soft zoning. Not sure why Brocade couldn't standardize their output using WWPN & WWNN instead. I am assuming the WWPN is the PermanentPort Name because that's the only WWN that allows me to use when I run a nodefind 10:00:00:05:33:21:4a:a3.

In the GUI under the Zone Admin, under the Member Selection List, creating aliases just checking which is best practices, Do you select the Parent or the Child when creating the alias?

Fabric Port Name: 20:09:00:05:33:33:02:42
Permanent Port Name: 10:00:00:05:33:21:4a:a3

Is the Permanent Port Name hard zoning or soft zoning

Thanks
