The following table describes the fields in this screen.
16.13 Queue Method
This feature is not available on all models.
Queuing is used to help solve performance degradation when there is network congestion. Use
the Switch Configuration: Switch Setup screen to configure queuing algorithms for
outgoing traffic.
Follow the steps below to configure queuing for each port.

2 Click Configuration, Ethernet Port Configuration and then the Queue Method tab.
3 Select the ports from the Port List Panel that you want to apply this configuration.
Table 73 Ethernet Port Configuration: VLAN Stacking
LABEL DESCRIPTION
Role Select Normal to have the switch ignore frames received (or transmitted) on this port with
VLAN stacking tags. Anything you configure in SPVID and Priority is ignored.
Select Access Port to have the switch add the SP TPID tag to all incoming frames received
on this port. Select Access Port for ingress ports at the edge of the service provider's
network.
Select Tunnel Port (available for Gigabit ports only) for egress ports at the edge of the
service provider's network. In order to support VLAN stacking on a port, the port must be
able to allow frames of 1526 Bytes (1522 Bytes + 4 Bytes for the second tag) to pass
through it.
SPVID SPVID is the service provider's VLAN ID (the outer VLAN tag). Enter the service provider ID
(from 1 to 4094) for frames received on this port. See the chapter on VLANs for more
background information on VLAN ID.
Priority Select the priority level of the inner IEEE 802.1Q tag.
"0" is the lowest priority level and "7" is the highest.
Apply Click Apply to save the changes.
