Description
Disable: Stop VLAN function on the switch. In this mode, no VLAN is applied
to the switch. This is the default setting.
Port-based: Port-based VLAN is defined by port. Any packet coming in or
outgoing from any one port of a port-based VLAN will be accepted. No
filtering criterion applies in port-based VLAN. The only criterion is the
physical port you connect to. For example, for a port-based VLAN named
PVLAN-1 contains port members Port 1&2&3&4. If you are on the port 1, you
can communicate with port 2&3&4. If you are on the port 5, then you cannot
talk to them. Each port-based VLAN you built up must be assigned a group
name. This switch can support up to maximal 12 port-based VLAN groups.
Tag-based: Tag-based VLAN identifies its member by VID. This is quite
different from port-based VLAN. If there are any more rules in ingress filtering
list or egress filtering list, the packet will be screened with more filtering
criteria to determine if it can be forwarded. The switch supports supplement
of 802.1q.
Each tag-based VLAN you built up must be assigned VLAN name and VLAN
ID. Valid VLAN ID is 1-4094. User can create total up to 64 Tag VLAN groups.
Metro Mode: The Metro Mode is a quick configuration VLAN environment
method on Port-based VLAN. It will create 10 or 11 Port-based VLAN groups.
Double-tag: Double-tag mode belongs to the tag-based mode, however, it
would treat all frames as the untagged ones, which means that tag with PVID
will be added into all packets. Then, these packets will be forwarded as
Tag-based VLAN. So, the incoming packets with tag will become the
double-tag ones.
This function is enabled only when metro mode is chosen in VLAN mode.
11: Except Port 11, each port of the switch cannot transmit packets with each
other. Each port groups a VLAN with Port 11, thus, total 11 groups
consisting of 2 members are formed.
12: Except Port 12, each port of the switch cannot transmit packets with each
other. Each port groups a VLAN with Port 12, thus, total 11 groups
consisting of 2 members are formed.
11 & 12: Except Port 11 and Port 12, each port of the switch cannot transmit
packets with each other. Each port groups a VLAN with Port 11 and Port 12,
thus, total 10 groups consisting of 3 members are formed.
