Currently PI 3.7 is polling our 9300 switch and getting almost all of the wired client information except the "User Name" which is normally the workstations host name. I swear the switches in our test environment and production are the same except it's not displaying on our production network. Both PI are connected to ISE and i've had to follow a few guides for SNMPv3 matching the context.
I'm using the default view for snmp-server on the switches. Switches on both environments aren't sending traps to the PI server. Also yes, PI can connect and is in the SNMP-R ACL along with it being able to connect via SSH.
currently what i have is
snmp-server group SYSTEM_GROUP v3 priv access SNMP-R
snmp-server group SYSTEM_GROUP v3 priv context vlan- match prefix access SNMP-R
snmp-server user PI_USER SYSTEM_GROUP v3 auth sha passwordgoeshere priv aes 128 passwordgoeshere access SNMP-R
snmp-server enable traps snmp authentication linkdown linkup coldstart warmstart
snmp-server enable traps envmon fan shutdown supply temperature status

It's just that stupid hostname i'm after, I was creating a API that would allow our help desk to look up by MAC or IP or Hostname and i've noticed that the hostname no longer displays on production. Do i need to include a view and would iso be sufficient or something else? Everything else is working great. Almost forgot that all of the wired client details display for wireless. Another note, When i try to view all ISE wired clients, i get nothing but i figured that's something else. I do have 2 off sites that are on 3850's and they display the wired clients hostname.
I did use these two as reference and still no hostname is being displayed:
