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 6
or 7 Port-based VLAN groups.
Symmetric Vlan This is a Ingress Rule (Rule 1, The Ingress Filtering Rule 1 is
“forward only packets with VID matching this port’s configured
VID”.). For example, if port 1 receives a tagged packet with
VID=100 (VLAN name=VLAN100), and if Symmetric-Vlan
function is enabled, the switch will check if port 1 is a member of
VLAN100. If yes, the received packet is forwarded; otherwise, the
received packet is dropped.
Note: If Symmetric is enabled and port 1, for example,
receives an untagged packet, the switch will apply the
PVID of port 1 to tag this packet, the packet then will be
forwarded. But if the PVID of port 1 is not 100, the
packet will be dropped.
SVL While SVL is enable, all VLANs use the same filtering
database storing the membership information of the VLAN
to learn or look up the membership information of the
VLAN. While SVL is disable, it means learning mode is
IVL. In this mode, different VLAN uses different filtering
database storing the membership information of the VLAN
to learn or look up the information of a VLAN member.
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.
Up-link Port: This function is enabled only when metro mode is chosen in
VLAN mode.
25 -
Except Port 25, each port of the switch cannot transmit
packets with each other. Each port groups a VLAN with Port
25, thus, total 25 groups consisting of 2 members are formed.
26 -
Except Port 8, each port of the switch cannot transmit
packets with each other. Each port groups a VLAN with Port
8, thus, total 26 groups consisting of 2 members are formed.
25 and 26 Port -
