vmps switch-port shutdown

[Habegger Lukas, ERZ-AZD-AID-NOC]

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
