VMPS on a Cisco 4006 switch??

[omegaamigo]

I am investigating the possibilities of using VMPS on my LAN. I have inherited a single Cisco 4006 switch, fully populated with 10/100 blades. The top module describes itself as "WS-X4013 Supervisor Engine II"

I have done the following:

set vmps downloadserver 10.1.1.9 vmps.dat
set vmps downloadmethod tftp
set vmps state enable

It downloads my vmps.dat file and says there are no errors.

My vmps.dat:

!VMPS File Format, version 1.1
vmps domain ceu
vmps mode open
vmps fallback --NONE--
vmps no-domain-req deny
vmps-mac-addrs
address 0004.7614.d0ff vlan-name Local
!
vmps-vlan-group davee
vlan-name Local
!
vmps-port-group daveeports
device 10.1.1.11 port 2/1
!
vmps-port-policies vlan-group davee
port-group daveeports

show vmps:

VMPS Server Status:
-------------------
Management Domain:    ceu
State:                enabled
Operational Status:   active
TFTP Server:          10.1.1.9
TFTP File:            vmps.dat
Fallback VLAN:        --NONE--
Secure Mode:          open
VMPS No Domain Req:   deny

VMPS Client Status:
---------------------
VMPS VQP Version:     1
Reconfirm Interval:   60 min
Server Retry Count:   3
VMPS domain server:   

No dynamic ports configured.

If I then set a port as dynamic at this stage, I see the error "DVLAN-1-NOVMPS:VMPS address not configured"

So, I assign a VMPS server address, which I assume is this switch itself - I've assigned address 10.1.1.201 to it. This is the part I'm unsure about.

set vmps server 10.1.1.201

show vmps now gives:

VMPS domain server:   10.1.1.201 (primary)

in addition to above config. Is this correct?

I then make port 2/1 dynamic:

set port membership 2/1 dynamic

However, if I now connect a desktop PC to port 2/1, it never changes from this status:

Port  Name               Status     Vlan
----- ------------------ ---------- ----------
 2/1                     inactive   dyn-

This port works fine as static, of course.

I've just read

http://www.cisco.com/en/US/products..._guide_chapter09186a00800915ba.html#wp1025956

which says that "The Catalyst 4000 family switches can function only as VMPS clients." and am totally confused. Is this why I'm having difficulties? Or have I missed something important in the VMPS setup? If this switch is capable only of functioning as a VMPS client, then why am I able to download the VMPS database into it via TFTP?

Any suggestions/help most welcome, thanks!
