Select this to enable VLAN stacking on the MES-2110.
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.
Role Select Access to have the MES-2110 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 (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.
