vmps switch-port shutdown

hi I try to shutdown (errdisabled) a port of a cisco3560 with the vmps-shutdown response. i use freeradius 2.1.10 and rlm_perl. Could someone tell me how the response should look like. so fare i have: $RAD_REPLY{'VMPS-Packet-Type'} = "VMPS-Join-Response"; $RAD_REPLY{'VMPS-Error-Code'} = "VMPS-Shutdown"; $RAD_REPLY{'VMPS-Sequence-Number'} = $RAD_REQUEST{'VMPS-Sequence-Number'}; i can set the vlan on a port for a specific mac but the port does not go to errdisabled when i use the above. Thanks for help Lukas
