Hello
After upgrading our 2960-X stacks from 15.2(6)E3 to 15.2(7)E1, dynamic vlan assignment through MAB works randomly.
We sometimes encounter this kind of errors :
%PM-3-INTERNALERROR: Port Manager Internal Software Error (vlan > 0 && vlan < PM_MAX_VLANS: ../switch/pm/pm_vlan.c: 878: pm_vlan_test_portlist)
the port stays in VLAN 1 and MAC address on the port is in "Drop" state in the MFT.
We have the problem only with 2960-X stacks in 15.2(7)E1, all others are working fine.
RADIUS Debug show that the Tunnel-Private-Group-Id is correctly received on the switch, but somehow is discarded.
Have you encountered the same issue ?
Thanks for your help
