WEB OPERATION & CONFIGURATION
4.3.22.3 IP Subnet-based VLAN
IP Subnet-based VLAN configuration is to map untagged ingress frames to a specific VLAN if the source address is
found in the IP subnet-to-VLAN mapping table. When IP subnet-based VLAN classification is enabled, the source
address of untagged ingress frames are checked against the IP subnet-to-VLAN mapping table. If an entry is found for
that subnet, these frames are assigned to the VLAN indicated in the entry. If no IP subnet is matched, the untagged
frames are classified as belonging to the receiving port’s VLAN ID (PVID).
VCE ID:
Index of the entry. Valid range is 0-256.
IP Address:
Indicate the IP address for this rule.
Mask Length:
Indicate the network mask length.
VLAN ID:
Indicate the VLAN ID
Port Members:
Assign ports to this rule.
Click the “Add New Entry” button to insert a new entry to the list.
Click the “Delete” button to remove a newly-inserted entry or select the checkbox to remove a saved entry during the
next save.
4.3.23 Voice VLAN
Nowadays, in the enterprise network, VoIP devices are commonly deployed to save operational cost due to its easy-
to-setup feature and convenience. However, while deploying VoIP devices, it is recommended that VoIP traffic is
separated from data traffic. By isolating traffic, VoIP traffic can be assigned to have the highest priority while
forwarding so that higher voice quality can be achieved without encountering situations like excessive packet delays,
packet loss, and jitters. Moreover,
This switch provides Voice VLAN feature that enables voice traffic to be forwarded on the voice VLAN. The user can
also overwrite traffic priority by assigning higher traffic class value to voice traffic. Voice traffic can be detected on a
port by using LLDP (IEEE 802.1ab) to discover VoIP devices attached to the switch or from devices’ OUI
(Organizationally Unique Identifier). When voice packets are detected on a port, the switch automatically assigns the
port as a tagged member of the Voice VLAN and forward packets based on configurations set in Voice VLAN
configuration page.
