Description
Port VLAN
Primary VLAN
ingress
retag-
untagged
Received frames without 802.1Q header are tagged with the
primary VLAN
drop untagged
Received frames are without 802.1Q header are discarded
egress
unmodified
Frames are sent unchanged. The Ingress mode with a retagging
has no effect on the sent frame.
discard-tag
The 802.1Q header of the frame is removed before it is sent.
with-tag
Frames without 802.1Q header receive an 802.1Q header and the
VLAN ID of the primary VLAN before sending.
7.1.2. VLAN groups
VLAN groups are pairs of a VLAN ID and a name. The VLAN ID has a value from 1 to 4095 and
occurs only once.
VLAN groups can only be removed if the group is not associated with any interface.
7.2.
QoS
Order No. 006-130-101/102
QoS (quality of service) enables prioritization of specific network traffic. The settings for QoS are
managed in the web interface at
Configuration > QoS
. The trust mode determines according to which
criteria a packet is prioritized. The trust modes VLAN and IP allows the sender of the packet to set the
priority with which the packet should to be treated.
Trust Mode
Description
none
All packages the "default ingress cos" is assigned
VLAN
If an incoming frame contains an 802.1Q header, the assigned COS value will
be used.
IP
If an incoming frame contains an 802.1Q header, the assigned DSCP value will
be used.
Thereafter, the packets are processed in different queues. QoS affects only the switch interfaces.
Queue ID
Description
3
The queue 3 is a priority queue. It will be processed as long as all frames are
transmitted. Data streams with high demands on latency and availability should
be associated with this queue. Keep in mind that a too high workload in this
queue can affect negatively the data streams of the other cues.
2
high prioritized fair weighted queue
1
normal prioritized fair weighted queue
0
low prioritized fair weighted queue
The remaining bandwidth after all frames were sent from queue 3 is divided according to the scheme
4-2-1 between the queues 2-0.
