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.

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.
