Chapter 21 VLAN Stacking Table 55 Advanced Application > VLAN Stacking (continued) 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 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 79 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. ES-3124 Series User's Guide 163
