Huawei alone is unable to collect or save the content of users' communications. It is suggested that you activate the interception-related functions based on the applicable laws and regulations in terms of purpose and scope of usage.

  • Page 4: Product Positioning And Characteristics

    1.4.1.1.2.1 Product Positioning NOTICE: The S2700 Series Ethernet Switches are class A products. The switches that are operating may cause radio interference. Customers need to take prevention measures. The S2700 Series Ethernet Switches (hereinafter referred to as the S2700) provide the access and data transport functions.

  • Page 5: Flexible Networking Capability

    The S2700 can be used to construct a tree, star, or ring Ethernet network. For the ring Ethernet, the S2700 supports the Spanning Tree Protocol (STP) to prevent loops and provide rapid switchover.

  • Page 6: Convenient Operation And Maintenance

    In addition to collecting traffic statistics based on interfaces and VLANs, the S2700 provides fault detection and location tools such as ping and traceroute on an IP network. It can also work with the Huawei eSight network management system (NMS) to implement performance monitoring, alarm report, and fast fault location.

  • Page 14: Flow Control On An Interface

    1.4.1.1.4.1.2 Flow Control on an Interface Flow control on an interface is a method of congestion management. It applies to all types of flows. The S2700 implements flow control on an interface by using the hardware backpressure mechanism. When an interface works in full duplex mode, the S2700 implements flow control complying with IEEE 802.3x.

  • Page 15: Qinq

    VLAN members are defined according to source MAC addresses of packets. When an interface of the S2700 receives a packet, the S2700 determines the VLAN ID of the packet according to the source MAC address of the packet and sends the packet on the corresponding VLAN.

  • Page 16: Gvrp

    In this way, packets from user networks are transmitted transparently on the public network, and thus user networks are separated from the public network. The S2700 supports the basic QinQ function. That is, all the frames that reach the public network through an interface are tagged with the same public VLAN ID.

  • Page 17: Mstp

    Loop Protection After loop protection is enabled on the S2700, it sets the root port to the Blocking state if the root port does not receive protocol BPDUs from the upstream device. If the port receives protocol BPDUs again, it becomes the root port and changes to the Forwarding state.

  • Page 18: Partitioned Stp And Bpdu Tunnel

    BPDU Tunnel On a partitioned STP network, the S2700 considers the tagged BPDUs as common Layer 2 frames. That is, the S2700 forwards the BPDUs within the VLAN to which the tag belongs rather than sending them to the MSTP module.

  • Page 20: Multicast

    When a multicast member leaves a multicast group, the host sends an IGMP Leave message. When an interface on the S2700 is connected to only one host, the S2700 deletes the multicast forwarding entry of the interface immediately after receiving the IGMP Leave message. This saves bandwidth and system resources and http://localhost:7890/printtopics.html?time=Thu Dec 10 16:53:17 UTC-0200 2015...

  • Page 21: Multicast Traffic Control

    When receiving unknown multicast packets, the S2700 discards the packets or broadcasts them on the VLAN that the inbound interface belongs to. The S2700 can also control inbound multicast traffic volume by limiting the percentage of multicast packets on an Ethernet interface.

  • Page 22: Traffic Classification

    S2700, the S2700 performs traffic policing and access control for the packets according to the committed information rate (CIR); when packets exit an S2700, the S2700 shapes the traffic of packets and re-marks the priorities of packets.

  • Page 23: Access Control And Re-Marking

    The S2700 uses the token bucket algorithm to control the Committed Access Rate (CAR) of network traffic. The S2700 controls the rate of traffic by adjusting the rate of placing tokens. Each token equals a forwarding rate of 64 kbit/s. The S2700 "punishes" the excessive traffic to limit the incoming traffic within a proper range and to protect the network resources.

  • Page 24: Aggregate Car

    1.4.1.1.5.4.1 Device Security Hierarchical Command Protection When a user logs in to the S2700 from an Ethernet interface through Telnet, the S2700 authenticates the user to ensure security. The user can configure and maintain the S2700 only after passing the authentication.

  • Page 25: Service Security

    HWTACAS+ authentication. CPU Channel Protection The S2700 can filter the protocol packets and management packets sent to the CPU based on the protocol ID, interface, and combination of interface and VLAN. This protects the CPU channels against Denial of Service (DoS) attacks.

  • Page 26: Security Authentication

    HEEX Startpage Page 26 of 34 Parent topic: Security 1.4.1.1.5.4.3 Security Authentication The 802.1x protocol is a port-based network access control protocol. It authenticates and controls access devices on a LAN based on interfaces. A user device can access resources on the LAN only after it passes the authentication on the access interface.

  • Page 27: Reliability

    Parent topic: Service Features 1.4.1.1.5.6 Reliability The S2700 supports MSTP to eliminate broadcast storms on a network and provide backup links for data transmission. The S2700 provides the root protection function. When the designated port receives a BPDU of higher priority, it remains the designated port for a certain period of time to protect the role of the root switch.

  • Page 28: Stacking

    Thus the NMS can manage a larger area on the network. The LLDP-enabled interfaces on the S2700 periodically notify the neighbors of its own status. If the status of an interface changes, the interface sends status update messages to the directly connected neighboring device. The neighboring device stores the status update message in the standard SNMP MIB.
