Configuring Handling of L2CP Frames L2CP Processing
o Transparent - passes the customer control frames invisibly through to the
provider's defined Egress Port without modifying the header. Be sure tunneling
is unidirectional and defined properly on either side of each link along the route.
Manually configure the reverse direction of a transparent tunnel on all ports
specified as Egress Ports.
o Tunnel by Tag Type - tags the frame and assigns it a VLAN ID. The frame is
then passed to the defined Egress Port and tunneled through the network as if it
was a regular data frame, according to the defined Tag and VLAN ID. After
reaching its destination (UNI) the tag and VLAN ID are removed. The
modifications are made only once on the CPE side. On the CO side, transparent
tunneling is used. The reverse direction of a tagged tunnel is defined
automatically on all ports specified as Egress Ports.
o Tunnel by MAC and VLAN ID - Modifies the customer frame DST address to
a configurable MAC (only unicast address can be set) and encapsulates the frame
within a VLAN tag (with a configurable VLAN ID and Ethernet Type which is
set according to Bridge configuration). The frame is then passed to the provider's
defined Egress Port and tunneled through the network as if it was a regular data
frame, according to the defined MAC and VLAN ID. After reaching its
destination (UNI), the MAC and VLAN ID are removed. The modifications are
made only once on the CPE side. On the CO side, transparent tunneling is used.
The reverse direction of a MAC tunnel is defined automatically on all ports
specified as Egress Ports.
NOTE: When using MAC tunneling, it is important to note the following:
a. MAC tunneling, when applied on STACKED ETH ports, works with
UNTAGGED L2CP reserved frames only.
b. MAC tunneling requires Actelis ML700 on both sides. The mechanism might
not work if the MAC tunnel is not terminated by an ML NE.
5. Define the Egress Port (any ETH, HSL or COLAN port) via which the handled frame
will be forwarded to the network as follows:
From the drop-down options box adjacent to the Add Port button, choose the Egress
port.
Click Add Port. The selected port will be added to the Egress Port list. (To remove a
port, choose the port from the list and click Remove Port).
Repeat to add another port (up to two) to the list.
6. Click OK.
