6.7 "Layer 2" menu
Table 2 has the following columns:
● Port
Shows the available ports and interfaces.
● Priority
From the drop-down list, select the priority given to untagged frames.
The CoS priority (Class of Service) used in the VLAN tag. If a frame is received without a
tag, it will be assigned this priority. This priority specifies how the frame is further
processed compared with other frames.
There are a total of eight priorities with values 0 to 7, where 7 represents the highest
priority (IEEE 802.1p Port Priority).
● Port VID
Select the VLAN ID from the drop-down list. Only VLAN IDs defined on the "VLAN >
General" page can be selected.
If a received frame does not have a VLAN tag, it has a tag with the VLAN ID specified
here added to it and is sent according to the rules at the port.
● Acceptable Frames
Specify which types of frames will be accepted. The following alternatives are possible:
– Tagged Frames Only
– All
– No Change
● Ingress Filtering
Specify whether the VID of received frames is evaluated.
You have the following options:
– Enabled
– Disabled
– No Change

The device discards all untagged frames. Otherwise, the forwarding rules apply
according to the configuration.
The device forwards all frames.
If "No Change" is selected, the entries of the corresponding column in table 2 remain
unchanged.
The VLAN ID of received frames decides whether they are forwarded: To forward a
VLAN tagged frame, the receiving port must be a member in the same VLAN. Frames
from unknown VLANs are discarded at the receiving port.
All frames are forwarded.
If "No Change" is selected, the entries of the corresponding column in table 2 remain
unchanged.
