Port VID
1
The VLAN ID assigned to untagged frames received on this
port.
Port Default
Priority²
0
Set the default ingress priority to any value beneath the
priority threshold (chapter 3 “Configuring Global Bridge
Settings”) to specify the low priority queue, or to any value
equal to or above this threshold to specify the high priority
queue.
VLAN
Tagging³
Layer 2 -
Rx All,
Tx All
Multilayer -
Rx All,
Tx Untag
Indicates whether or not VLAN tags will be included on frames
transmitted out of this port. The options include:
Rx All:
Accepts all frames, tagged or untagged.
Rx Untag: Only accepts untagged frames.
Tx All:
If PVID and frame tag are same, sends tagged
frame, otherwise send untagged.
Tx Untag: Sends only untagged frames.
Port
GVRP
Enabled
Enables or disables GVRP for this port. When disabled, any
GVRP packets received on this port will be discarded and no
GVRP registrations will be propagated from other ports.
Note that GVRP must be enabled globally for the switch
before this setting can take effect. (See “Configuring Global
Bridge Settings” on chapter 3.)
Port
GMRP
Enabled
Enables or disables GMRP for this port. When enabled, this
port will allow endstations to register with multicast groups
using GMRP.
Note that GMRP must be enabled for the switch before this
setting can take effect (chapter 3 “Configuring Global Bridge
Settings”).
IGMP and IGMP Snooping also provide multicast filtering. For
multilayer mode, the full IGMP protocol set is automatically
enabled / disabled along with DVMRP. (See “IGMP Protocol”
on chapter 4, “Configuring DVMRP” on chapter 3, and
“Configuring IGMP Snooping” on chapter 3.)
Ingress
Filtering
4
Disabled If enabled, incoming frames for VLANs which do not include
this ingress port in their member set will be discarded at the
ingress port.
2. This switch supports Quality of Service (QoS) by using two priority queues, with
Weighted Fair Queuing for each port. Inbound frames that do not have VLAN tags
are tagged with the input port’s default ingress user priority, and then placed in the
appropriate priority queue at the output port. The default priority for all ingress ports
is zero. Therefore, any inbound frames that do not have priority tags will be placed in
the low priority queue of the output port. (Note that if the output port is an untagged
member of the associated VLAN, these frames are stripped of all VLAN tags prior to
transmission.)
3. If you want to create a small port-based VLAN for just one or two switches, you can
assign ports to the same untagged VLAN (and use a separate connection where a
