Chapter 21 VLAN Stacking 157
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 81 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 to the switch’s run-time memory. The switch loses these
changes if it is turned off or loses power, so use the Save link on the top navigation panel to
save your changes to the non-volatile memory when you are done configuring.
Cancel Click Cancel to begin configuring this screen afresh.
