DESCRIPTION
Select Access to have the Switch encapsulate the incoming layer 2
protocol packets and forward them to the tunnel port(s). Select Access
for ingress ports at the edge of the service provider's network.
Note: You can enable L2PT services for STP, LACP, VTP, CDP,
UDLD, and PAGP on the access port(s) only.
Select Tunnel for egress ports at the edge of the service provider's
network. The Switch decapsulates the encapsulated layer 2 protocol
packets received on a tunnel port by changing the destination MAC
address to the original one, and then forward them to an access port. If
the service(s) is not enabled on an access port, the protocol packets are
dropped.
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.
Click Cancel to begin configuring this screen afresh.
