This object is used to enable or disable the snooping module functioning in the enhanced mode. By default, the snooping module operates in the normal or default mode. In the default mode, the module multicasts from an Outer VLAN (SVLAN) to a set of ports. The Inner VLAN (CVLAN) will typically have a value of zero. In this mode, an S-tagged multicast data or query packet from one port can result in multiple packets on separate egress ports, but only one packet on any one egress port with an S-tag or with no tag. Enabling this object causes the snooping module to operate in the enhanced mode. The module multicasts from an Outer VLAN (SVLAN) to a set of ports & Inner VLANs (CVLAN). In this mode, an S-tagged multicast data or query packet from one port can result in multiple copies of the packet on the same egress port, each with a different C-tag. The Inner VLAN (CVLAN) will typically have a valid value within the designated range. However under certain scenarios, the Inner VLAN may also have a value of zero. Disabling this object causes the snooping module to operate in the default mode.
