finds out the port connected to user network 2 is customer port, removes the external
label according to the conventional 802.1Q protocol, restores it to the original packet, and
sends it to user network 2.
The data between user network 1 and 2 can be transmitted transparently via SP network.
User networks can freely plan their own private network VLAN ID to avoid the conflict with
SP network VLAN ID.
3.1.3 STP features
Support RSTP and MSTP as well as such protection features as bpdu guard, root guard
and loop guard.
3.1.4 Link aggregation
Link aggregation, known as Trunk, binds several physical ports into one logic port to
share incoming/outgoing traffic load among member ports. The switch decides according
to port load sharing policy configured by the user via which member port the packet is
sent to the opposite switch. When detecting that a fault occurs to the link of a member
port, the switch will stop sending the packet via the port, and recalculate and decide a
port for packet transport according to load sharing policy. After the faulty port restores,
the switch will recalculate and decide a port for packet transport again. Link aggregation
is an important technology to increase link bandwidth and support link transport resilience
and redundancy.
ZXR10 5250 supports static Trunk and LACP link aggregation.
Static Trunk adds several physical ports directly to Trunk group to form one logic port, but
it is not good at observing the status of link aggregation port.
LACP (Link Aggregation Control Protocol), following IEEE 802.3ad, dynamically
aggregates several physical ports into Trunk group through the protocol to form one logic
port. LACP automatically aggregates to get the maximum bandwidth.
3.1.5 Basic Ethernet features
ZXR10 5250 supports the following basic Ethernet features:

Support port mirroring
Port mirroring copies the data of one or several switch ports (mirrored port) to one
designated destination port (monitored port) to get the data of the monitored port for
traffic analysis and wrong diagnosis port data. The mirroring (RSPAN) of
cross-equipment ports is supported.

Support broadcast storm suppression
