The following table describes the labels in this screen.

Table 51 VLAN Stacking

LABEL DESCRIPTION

Active Select this checkbox to enable VLAN stacking on the switch.

SP TPID SP TPID is a standard Ethernet type code identifying the frame and indicates whether the

frame carries IEEE 802.1Q tag information. Choose 0x8100 or 0x9100 from the drop-down

list box or select Others and then enter a four-digit hexadecimal number from 0x0000 to

0xFFFF. 0x denotes a hexadecimal number. It does not have to be typed in the Others text

field.

Port The port number identifies the port you are configuring.

* Settings in this row apply to all ports.

Use this row only if you want to make some settings the same for all ports. Use this row first

to set the common settings and then make adjustments on a port-by-port basis.

Note: Changes in this row are copied to all the ports as soon as you make

them.

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 are 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 Chapter 8 on page 85 for more

background information on VLAN ID.

Priority On the switch, configure priority level of inner IEEE 802.1Q tag in the Port Setup screen.

"0" is the lowest priority level and "7" is the highest.

Apply Click Apply to save your changes back to the switch.

Cancel Click Cancel to begin configuring this screen afresh.
