Configuring Port MAC Duplication

mac-duplicate <0-4>
no mac-duplicate <0-4>
Note:
Port is configured as customer port of SVLAN based on ACL. The
learning L2 entry on port is vlan id of inner tag , need to enable
MAC duplication for customer port. CPU duplicates a L2 entry of
outer tag vlan id, downlink packet can get customer port informa-
tion according to outer vlan id L2 entry.

Configuring Port LOOPBACK

Configure uplink port of SVLAN based on ACL to implement loop-
back. At this time ,the port doesn't send packet. All packets are
loopback on this port and forwarded to other ports in the same
vlan. In one vlan, at least two ports should exist to send packets
as SVLAN uplink port.
loopback {enable|disable}
Note:
When loopback enable is configured, port learning function will be
closed automatically, whereas port learning function is opened au-
tomatically when loopback disable is configured. Loopback port
as uplink port of SVLAN only receives packet that SVLAN cus-
tomer port redirects after adding tags and loopbacks to uplink port,
which doesn't receive packet forwarded by uplink port. Therefore
it needn't port learning function. If port learning function is not
disabled, port learns L2 entry when loopbacking message, which
causes L2 entry, set by MAC duplication function on customer port,
to be coverd.
