Parameter description:
Port 1-26:
Port number.
PVID:
This PVID range will be 1-4094. Before you set a number x as PVID, you
have to create a Tag-based VLAN with VID x. For example, if port x
receives an untagged packet, the switch will apply the PVID (assume as
VID y) of port x to tag this packet, the packet then will be forwarded as
the tagged packet with VID y.
Symmetric/Asymmetric:
Forward only packets with VID matching this port’s configured VID. You
can choose “Symmetric” as a way for all ports to filter unwanted traffic. In
Symmetric Mode, a given port checks if the given port is a member of the
VLAN on which the received packet belongs to, to determine forward it or
not. For example, if port 1 receives a tagged packet with VID=100 (VLAN
name=VLAN100), and if “Symmetric/Asymmetric” is Symmetric, the
