MVR : MVR is used to eliminate the need to duplicate multicast traffic for subscribers
in each VLAN. Multicast traffic for all channels is sent only on a single (multicast) VLAN.
MSTP : The 802.1s Multiple Spanning Tree protocol (MSTP) uses VLANs to create
multiple spanning trees in a network, which significantly improves network resource
utilization while maintaining a loop-free environment.
Port :
The logical port for the settings contained in the same row.
Port Type :

not removed. C-port is Customer Port. S-port is Service port. Custom S-port is
S-port with Custom TPID.
