3-6-3. PVID
Function name:
PVID
Function description:
In PVID Setting, user can input VID number to each port. The range of VID
number is from 1 to 4094. User also can choose ingress filtering rule (Rule 2)
to each port. The Ingress Filtering Rule 2 is “drop untagged frame”. While Rule
2 is enabled, the port will discard all Untagged-frames.
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.
Default Priority:
If a tagged frame does not own a VID, the Ingress rule will plus a tag with
default priority and PVID.
Drop Untag:
Drop untagged frame. You can configure a given port to accept all frames
(Tagged and Untagged) or just receive tagged frame. If the former is the
case, then the packets with tagged or untagged will be processed. If the
later is the case, only the packets carrying VLAN tag will be processed,
the rest packets will be discarded.
