3 Functions
3.1 Basic Function
3.1.1 MAC Address Management
MAC（Media Access Control）is the hardware label of network equipment. The switch
implements message forwarding according to MAC address. As an exclusive tag, MAC
address ensures the correct forwarding of messages.
Each switch takes care of a MAC address table. In this table, MAC address and switch
port are corresponding one by one. When the switch receives data, it will find out if this
data should be filtered or forwarded to the corresponding switch port in terms of MAC
address table. MAC address table is the foundation and premise for switch to implement
fast forwarding.
ZXR10 5900E series realizes the following MAC services:
MAC Address Fixation
When the network is operated steadily for a while, the locations of the equipment
linking to all ports of the switch are fixed. In other words, the ports corresponding to
all equipment’s MAC address in switch MAC address table are fixed, so the learnt
MAC address can be fixed.
MAC address fixation actually changes all dynamic MAC addresses to static mode.
After the conversion, these MAC addresses will not join in aging process. At the
same time, if the data from whose source MAC address are these addresses
appears on other ports, the switch will not have any chance to learn again any
more.
Port Binding MAC Address

ZXR10 5900E Product Description
ZTE Confidential Proprietary 15
It is capable of adding dynamic, static and permanent MAC addresses in MAC
address table. For static or permanent MAC address, the relationship between MAC
address and port is fixed. This relationship will not stop until it is removed manually.
Restrict the Number of Port MAC Address
The capacity of switch MAC address is limited. When the number of the user in the
network reaches the limitation of the MAC address table, we can restrict the number
of the learnt MAC address that the port of the users with low priority is.
By restricting port MAC address, MAC address flooding which easily causes MAC
address table overflow can be avoided.
Port MAC Address Learning Protection
When abnormity of one port MAC address learning is found, the switch will protect
this port MAC address learning for a while. As soon as the port goes into protection
mode, it will not carry out any new MAC address learning; when the protection is
due, the port can implement MAC learning again.
The Filtering of Port Unknown MAC Address
In default mode, the filtering service of unknown MAC address of switch port is
disabled. The port does not filter unknown MAC address. If unknown MAC address
filtering service is configured on one port of the switch, the corresponding port will
discard and learn the packets with the unknown MAC address got by this port.
MAC Address Filtering
The data filtering in terms of MAC address consists of the following three modes:
Only match the source MAC address of the data, i.e. if the source MAC
address of the data is the set MAC address, then carries out the filtering.
Only match the destination MAC address of the data, i.e. if the destination
MAC address of the data is the set MAC address, then carries out the filtering.

ZXR10 5900E Product Description
16 ZTE Confidential Proprietary
Match the source or destination MAC address of the data, i.e. if the source or
destination MAC address of the data is the set MAC address, then carry out
the filtering.
3.1.2 VLAN
ZXR10 5900E series have basic L2/L3 switching functions. The forwarding carried out in
data link layer realizes the classification of virtual working group by supporting IEEE
802.1Q protocol. ZXR10 5900E series supports multiple ways to classify VLAN, i.e. the
classification based upon equipment port, or the classification based upon the host MAC
address and the network layer information of user’s message.
3.1.2.1 Port-Based VLAN
The port-based VLAN classification is simple and popular. It allocates different ports of
the equipment with different VLAN, so all traffics received by these ports belong to the
VLAN corresponding to this port.For example, port 1,2 and 3 belong to the same VLAN,
other ports belong to other VLANs, as a result, and the frames received by port 1 are only
delivered to port 2 and port 3. If the VLAN user moves to a new place, it will not belong to
its original VLAN unless it is allocated with a new VLAN.
3.1.2.2 Protocol–Based VLAN
Protocol-based VLAN is flexible, so it is suitable for L3 or network with rich protocols.
Protocol-based VLAN is classified in terms of data packet’s network layer encapsulation
protocol, so the labels with the same data packet are in the same protocol VLAN. This
VLAN based upon network layer protocol enables broadcasting domain to cross multiple
VLAN switch. Therefore, users can move freely in the network, and its VLAN
membership will still remain.
Via this method, even user changes its location, he does not have to reconfigure its
VLAN. Besides, it can classify VLAN according to protocol type. Without requiring
additional frame label to mark VLAN, this method reduces network communications.

ZXR10 5900E Product Description
ZTE Confidential Proprietary 17
Protocol VLAN is set “enable”on the physical interface, and it can be disabled as
customer requires. It only classifies VLAN according to data packet label. It isolates
packets with different labels.
3.1.2.3 Subnet VLAN
Subnet VLAN is implemented in L2 VLAN, realizing data frame forwarding flexible.
Subnet VLAN determines the corresponding VLAN data will be forwarding according to
the source IP address of the data frame. This VLAN based upon the source IP address
enables users in different network segments cross multiple VLAN forwarding. But their
VLAN membership will still remain.
Subnet VLAN isolates data with different source IP addresses. So users can only get
data from the same network segment. The priority for UNTAG frame to forward subnet
VLAN is higher than protocol VLAN and PVID, TAG frame is forwarded in TAG mode,
and its priority is higher than subnet VLAN.
3.1.2.4 PVLAN
To enhance network security and isolate messages between users, each user will be
distributed with one VLAN traditionally. This method has the following obvious
drawbacks:
Currently 4094 VLANs are supported at most in IEEE 802.1Q standard. So the
limitation of the user number stops network extension.
Each VLAN is corresponding to one IP sub-net, so many subnets will cause the
waste of IP address.
The planning and management of so many VLAN and IP subnets make network
management more complicated.
PVLAN（Private VLAN）aims at solving these problems.
PVLAN divided VLAN port into two categories: Isolate Port connecting with user’s port
and Promiscuous Port uplinking router. The isolate port which can’t connect with each
other can only communicate with promiscuous port. Therefore, ports under the same

ZXR10 5900E Product Description
18 ZTE Confidential Proprietary
VLAN are isolated, and user can communicate with its default gateway only.It tightly
ensures network security.
3.1.2.5 VLAN Translation
VLAN translation is also an expansion of the VLAN function. It allows overlapping VLAN
IDs of different Ethernet switches accessing from the edge, and via VLAN translation
service, these overlapping VLAN IDs will be changed to different VLAN IDs and sent via
uplink port. So that users can be isolated in L2 core switch, which simplifies the
configuration of edge access switch.
3.1.2.6 Super VLAN
The traditional ISP network allocates each user an IP subnet. There are three IP
addresses used as subnet network number, broadcasting address and default gateway
respectively when every subnet is allocated. If there are lots of IP address remained in
some users’subnet, they can’t be used by other users either. This method may waste a
great number of IP addresses.
SuperVLAN solves this issue perfectly by aggregating multiple VLANs (normally called
sub-VLAN) to one SuperVLAN. These VLANs use the same IP subnet and default
network gateway.
Via SuperVLAN technology, ISP only needs to allocate one IP subnet to SuperVLAN,
and create one sub-VLAN to each user. All sub-VLANs can allocate IP addresses in the
subnet of SuperVLAN flexibly. They use the default gateway of SuperVLAN. Each VLAN
is an independent broadcasting domain, making sure the isolation of different users.
Different VLAN use SuperVLAN to route and communicate with each other.
3.1.2.7 QinQ
QinQ, also known as VLAN stacking, is a vivid name for the tunnel protocol based on
802.1Q encapsulation. Besides original VLAN label (Inner Label), QinQ technology adds
another VLAN label (Outer Label) which can cover the inner label.
