When i enable MVR on a cisco 3750 switch i seem to loose all SAP announcements.
EG with mvr:
mvr vlan 501
mvr mode dynamic
switchport access vlan 4
switchport trunk encapsulation dot1q
switchport trunk native vlan 501
switchport mode access
switchport voice vlan 5
mvr type receiver
No sap at all on the vlan 501
if i let the port direcly acess vlan 501 i do see SAP announcements on the port. Do you guys have any idea where to start to search what kills SAP in mvr mode?
