MLS problem

[nicolast]

Hello All,

I have configured MLS on a 6509 with a MSFC. When i do a 'show mls rp ip' on the MSFC, i got the following message at the end :
...
1 management interface(s) currently defined:
vlan 1 on Vlan1

2 mac-vlan(s) enabled for ip multi-layer switching:

mac 0004....
vlan id(s)
9 100

router currently aware of following 0 switch(es):
no switch id's currently exists in domain

The MLS seems to work but the router do not see the switch!?
Strange ???
