vmpsVlanConfigTable
vmps Vlan Config Table
1.3.6.1.4.1.9.9.53.1.2.2
A list of VLANs with restricted access from dynamic ports. This list takes the form of a group of VLANs and a group of ports permitted for those VLANs. If no entry exists for a particular VLAN then there are no restrictions as to what ports are allowed to access that VLAN. If entries exist for a VLAN, then all ports not explicitly permitted for that VLAN are denied access (in the form of a failed configuration response).
