4.4.1 Management VLAN
Management VLAN settings allow administrator to access the switch and perform the switch manage-
ment over a dedicated VLAN.
The following rules are applied with the Management VLAN:
1. If the VLAN function is disabled, Management VLAN settings are ignored and no VLAN
limitation is applied in accessing the switch web management interface. The switch web (http)
server only accepts untagged management packets and replies untagged packets to the manage-
ment host.
2. If [Management VLAN - VID] settings is zero, no VLAN limitation is applied in accessing the
switch web management interface. The switch web (http) server only accepts untagged manage-
ment packets and replies untagged packets to the management host.
3. If [Management VLAN - VID] settings is not zero, The switch web (http) server only accepts
tagged management packets matched [Management VLAN -VID] and replies tagged packets
with tag composed of [Management VLAN] VID, CFI and User Priority settings to the manage-
ment host. The egress port will also be limited in the member ports of the matched VLAN group.
