VLAN Subnet based VLAN allows you to group traffic into logical VLANs based on the source IP subnet you specify When a frame is received on a port the GLC1320G 55 checks if a tag is added already and the IP subnet it came from The untagged packets from the same IP subnet are then placed in the same subnet based VLAN One advantage of using subnet based VLANs is that priority can be assigned to traffic from the same IP subnet xVLAN XVLAN changes the VLAN IDs VIDs of subscriber traffic before sending it to the service provider s network It also changes the VI Ds of traffic from the service provider s network before sending it to the subscriber This lets you use unique VLANs for each subscriber but still deploy all the CPE devices with the same VLAN configuration Upstream Broadcast Storm Control Broadcast storm control lets you set limits for how many broadcast multicast and destination lookup failure DLF packets a port receives per second from the subscriber Downstream Broadcast VLAN Control Downstream broadcast VLAN control allows you to block downstream broadcast packets from being sent to specified VLANs on specified ports This helps to reduce downstream bandwidth requirements on a subscriber line MAC Count Limit You can limit the number of MAC addresses that may be dynamically learned on a port You may enable disable the MAC count filter on individual ports Rate Limiting Rate limiting on the subscriber ports allo
