Hello,
i have attached a IP-Phone (tagged vlan 1540) to my HP 2920 48G-PoE. The Phone got 1 PC-Port to attach a PC behind the Phone.
Port Authentication against Radius is active. Pohne is working well. If i attach a PC to the Phone , then the Switchport on 2920 got blocked. What do i need to change ?
Port Konfig:
tagged vlan 1540
untagged vlan 1520
aaa port-access authenticator
aaa port-access authenticator unauth-vid 1
loop-protect
exit
LOG:
I 02/06/18 10:05:01 00435 ports: ST2-CMDR: port 2/7 is Blocked by STP
I 02/06/18 10:05:00 00435 ports: ST2-CMDR: port 2/7 is Blocked by AAA

Thanks in advance.

Just a wild guess, try to set the client limit too 2.
kind regards
Yep, that should do it.
The problem you see is not STP, it's that the phone and the pc continuously try to authenticate and the port goes through the process of coming up.
You probably also see that in the RADIUS log
