The name defined by administrator is associated with a VLAN group. Valid letters
are A-Z, a-z, 0-9, “ - “ and “_”.
The maximal length is 15 characters.
VLAN ID:
VLAN identifier. Each tag-based VLAN group has a unique VID. It appears only in
tag-based and Double-tag mode.
IGMP Proxy:
IGMP proxy enables the switch to issue IGMP host messages on behalf of hosts
that the system discovered through standard IGMP interfaces. The system acts as
a proxy for its hosts. This switch can be set IGMP function “Enable” or “Disable”
by VLAN group. If the VLAN group IGMP proxy is disabled, the switch will stop the
exchange of IGMP messages in the VLAN group members. If the VLAN group
IGMP proxy is enabled, the switch will support the exchange of IGMP messages in
the VLAN group members and follow up IGMP proxy router port configuration,
which connects to a router closer to the root of the tree. This interface is the
upstream interface. The router on the upstream interface should be running IGMP.
You enable IGMP on the interfaces that connect the system to its hosts that are
farther away from the root of the tree. These interfaces are known as downstream
interfaces. Please refer to 3-15-1 for detail IGMP Proxy function description.
Member Port:
This is used to enable or disable if a port is a member of the new added VLAN,
“Enable” means it is a member of the VLAN. Just tick the check box (;) beside
the port x to enable it.
Add new VLAN:
Please click on <Add new VLAN> to create a new Tag-based VLAN. Input the
VLAN name as well as VID, configure the SYM-VLAN function and choose the
member by ticking the check box beside the port No., then, press the <Apply>
button to have the setting taken effect.
