ZXR10 5900/5200 Series User Manual (Ethernet Switching Volume) Assume ports 1, 2 and 3 belong to the same VLAN, while the other ports belong to other VLANs, then frames received on port 1 are broadcast to ports 2 and 3 only while they are not passed to any other port. When a user in a VLAN moves to a new location, it no longer belongs to the original VLAN unless the user is assigned to that VLAN again.
Chapter 1 VLAN Configuration It connects two devices that can identify VLAN tags and carries several VLAN’s services. It transmits tagged frames only to several VLANs. The most common trunk link is the one between two VLAN switches. 3. Hybrid Link It transmits both tagged and untagged frames. For a given VLAN, however, it only transmits frames of the same type.
ZXR10 5900/5200 Series User Manual (Ethernet Switching Volume) QinQ QinQ, also known as VLAN stack, is a graphic name for the IEEE 802.1Q based tunnel protocol. QinQ technology encapsulates the original VLAN tag (inner tag) with another VLAN tag (outer tag) so that the inner tag is masked. QinQ implements simple Layer 2 VPN (L2VPN) without protocol support, applicable to small-sized LANs with L3 switches as their core. QinQ typical networking is shown in Figure 2.
Chapter 1 VLAN Configuration Subnet VLAN isolates data frames from different source IP addresses so that a user has access to data from its own subnet only. The subnet VLAN priority in untagged frame forwarding is higher than that of protocol VLAN or PVID; the priority of tagged frame forwarding in the tagged mode is higher than that of subnet VLAN. Port is enabled on Subnet VLAN by default and also can be disabled according to actual demands.
ZXR10 5900/5200 Series User Manual (Ethernet Switching Volume) gateway address. Even if there are a number of idle IP addresses in a user’s subnet, they cannot be allocated to other users. This causes waste of IP addresses. SuperVLAN effectively resolves this problem. It merges several VLANs (called sub-VLAN) to a SuperVLAN so that they can use the same IP subnet and default gateway. With the SuperVLAN technology, the ISP needs only one IP subnet for its SuperVLAN.
Chapter 1 VLAN Configuration + VLAN ID. VLAN ID includes four digits (0s are pretended when there are less than four digits). Name of VLAN 4 is VLAN0004. Setting VLAN Link Type on Ethernet Interface To set VLAN link type on Ethernet port, use the following command. Command Function ZXR10(config-gei_1/x)#switchport mode {access|trunk This sets VLAN link type on Ethernet port. |hybrid} There are three VLAN link types for Ethernet interface of ZXR10 5900/5200: Access mode, Trunk mode and Hybrid mode.

Chapter 5 MAC Address Table Configuration Table of Contents Introduction to MAC Address ...............................................31 Configuring MAC Address Table............................................33 MAC Address Table Configuration Example ............................39 Introduction to MAC Address MAC Media Access Control address is the hardware identification of a network device. The switch forwards packets based on MAC address. MAC address is unique, ensuring accurate packet forwarding.
ZXR10 5900/5200 Series User Manual (Ethernet Switching Volume) � toS: Whether the MAC address is solid. � srF: Whether to drop frames from the source MAC address. � dsF: Whether to drop frames from the destination MAC address. � Time: the time of MAC address on the switch. Desiganated by day:hour:minute:second. During L2 forwarding, the switch checks its MAC address table for the destination MAC address of the received frame, and then forward data to the corresponding port.
Chapter 5 MAC Address Table Configuration Dynamic MAC addresses in the MAC address table are learned by the switch. The procedure of switch learning MAC address is as follows: Switch analyzes the source MAC address and VLANID (for example, MAC1+VID1) once it receives a data frame on a port. If judging the MAC address to be valid and learnable, the switch checks MAC1+VID1 in its MAC address table. If the entry is not found, the address is added to the MAC address table, otherwise the entry is updated.
ZXR10 5900/5200 Series User Manual (Ethernet Switching Volume) The configuration of MAC address table includes the following contents. Setting MAC Address Aging Time MAC address aging time influences the switch’s performance. A shorter aging time may make the switch delete useful MAC address table entries. As a result, it broadcasts many packets it loses track to their destination MAC addresses, which consumes the bandwidth.
Chapter 5 MAC Address Table Configuration of switch connects are fixed, that is, the interface that each device MAC address in switch MAC address table corresponds is fixed, then make the mac address that learns from port and will learn from port permanent to prevent MAC deceiving format network attack. Even if after device is rebooted, these MAC addresses still can be used. Of course, the premise is that automatic writing function is opened or write operation is implemented.
ZXR10 5900/5200 Series User Manual (Ethernet Switching Volume) Step Command Function 1 ZXR10(config)#mac add {dynamic|static|perman ent} interface [vlan ] When adding MAC address, if the VLAN ID is not designated , add according to port PVID. 2 ZXR10(config)#mac delete {| interface | vlan } If a VLAN ID is not specified while deleting a MAC address, all entries matching will be deleted.
Chapter 5 MAC Address Table Configuration Setting MAC Address Learning Protection ZXR10 5900/5200 supports MAC address learning protection function for ports. When a port is detected to be learning MAC addresses abnormally, its address learning will be suspended for some time. A port in protection state cannot learn new addresses. It recovers learning when the protect time is due. For setting MAC Address learning protection on a port, perform the following steps. 1.
ZXR10 5900/5200 Series User Manual (Ethernet Switching Volume) Setting MAC Address Filtering To prevent unauthorized access, ZXR10 5900/5200 support filtering data frames according to MAC addresses. There are three filtering modes: � Source MAC address matching only, that is, a data frame is dropped when its source MAC address matches the setting. � Destination MAC address matching only, that is, a data frame is dropped when its destination MAC address matches the setting.
Chapter 5 MAC Address Table Configuration MAC Address Table Configuration Example As shown in Figure 6, switches A and B are connected over trunk link smartgroup1, three PCs and a ZXR10 2826E are connected to switch B.

ZXR10 5900/5200 Series User Manual (Ethernet Switching Volume) RSTP Mode Rapid Spanning Tree Protocol (RSTP) provides a faster aggregation speed than STP (that is, SSTP mode). When the network topology changes, the state of the redundant switch port can make a fast shift (Discard > Forword) in the case of point-to-point connection. MSTP Mode Two concepts are added to Multiple Spanning Tree Protocol (MSTP): instance and VLAN mapping. SSTP/RSTP mode can be regarded as a special case of the MSTP mode.
Chapter 6 STP Configuration Note: Bridges in an MST area mush have same MST config ID. Two bridges with same MST config ID are probably in different MST area. For example, if two bridges with the same MST config ID are connected through the LAN of another MST area, they should belong to different MST area. MST area may have different spanning tree structures: Internal Spanning Tree (IST), MST1, MST2 and MSTn. Each MSTi can be regarded as an MSTI.
ZXR10 5900/5200 Series User Manual (Ethernet Switching Volume) BPDU Protection BPDU Overview Switches calculating spanning tree according to the content of BPDU packet. Network topology once changes spanning tree will be calculated again. If the network is large, the calculation will be very frequent. This influence switches to transmit packet. At the same time, the change of Root Bridge also brings some problem. BPDU protection overcomes these problems.
Chapter 6 STP Configuration packet and shut down the port which connects to switch D. This solves the problem of network performance. Port Loopback Protection Function Loopback protection provides addtional layer 2 protection function. One reason for STP loop takes places in a network with redundant link is that one port which in blocking state becomes a designated port and enters into FORWARDING state. A blocking port when doesn’t receive a BPDU packet. STP thinks that there isn’t a loop.
ZXR10 5900/5200 Series User Manual (Ethernet Switching Volume) FIGURE 9 NETWORK LOOP DIAGRAM In Figure 9, if port loopback protection is not configured. After MAX_AGE timer expires, blocking port in switch C will be transmitted into LISTENING state and then FORWARD_DELAY time is transmitted into LEARNING state. This cycle is repeated again then this will lead to loop. FIGURE 10 PORT LOOPBACK PROTECTION In Figure 10, if port loopback protection is configured.
Chapter 6 STP Configuration state after MAX_AGE time. Port in LOOP_INCONSISTENT state won’t transmit data. This will avoid looping. Port Root Protection Function Port root protection function provides a way to protect root switch. In switch environment, all switches which enable spanning-tree will take part in the election of root switch. Switch which has the lowest priority will be root switch.
ZXR10 5900/5200 Series User Manual (Ethernet Switching Volume) FIGURE 12 NEW ROOT BRIDGE In Figure 12, switch D takes part in calculating spanning tree. If priority of switch D is lower than that of switch A. Switch D is elected to be a new root switch. After calculating spanning tree, port of switch B which connects to switch A is blocked. Port root protection command is configured in interface mode. It is only permitted in designated port and is not permitted in root port.
Chapter 6 STP Configuration Configuring STP Enabling/Disabling STP Command Function ZXR10(config)#spanning-tree {enable|disable} This enables or disables STP. Note: Disable STP on ZXR10 5900/5200, all ports that physical status is up are set Forwarding status. In default, STP is disabled. Configuring STP Mode Command Function ZXR10(config)#spanning-tree mode {sstp|rstp|mstp} This configures STP mode. By default, STP mode of ZXR10 5900/5200 is MSTP.
ZXR10 5900/5200 Series User Manual (Ethernet Switching Volume) It is decided by the area root node of an instance in the MST area and decreases by 1 after each switch. When it decreases to 0 the BPDU packet is invalid. Message-age and max-age values of the BPDU packet in the MST area do not change during area transmission. To configure STP protocol parameters , use the following commands. Step Command Function 1 ZXR10(config)#spanning-tree hello-time
Chapter 6 STP Configuration Note: ZXR10 5900/5200 has on instance 0 only in SSTP/RSTP mode. In MSTP mode, the instance 0 exists by default and cannot be deleted at all. Configuring MSTP Name and Version Step Command Function 1 ZXR10(config-mstp)#name This configures MST configuration name. 2 ZXR10(config-mstp)#revision This configures version number. Note: Four conditions decide whether switches belong to same MST area: same MST configuration, same MST configuration version No.
ZXR10 5900/5200 Series User Manual (Ethernet Switching Volume) Note: Bridge and port priority of ZXR10 5900/5200 must be configured after the instance has been created. Excluding a Port from Spanning Tree Calculation In some cases, it is necessary to exclude a port from spanning tree calculation such as uplink port of switch or the port connecting to PC.
