  • Page 14: Introduction To Dldp

    Quidway S3700 Series Ethernet Switches Configuration Guide - Reliability 1 DLDP Configuration 1.1 Introduction to DLDP This section describes the concept of DLDP. On a network, unidirectional link faults often occur. That is, the local device can receive packets from the remote device through the link layer, but the remote device cannot receive packets from the local device.

  • Page 15: Configuring Dldp Functions

    Quidway S3700 Series Ethernet Switches Configuration Guide - Reliability 1 DLDP Configuration physical link, and DLDP identifies the remote device and unidirectional link and disables unreachable interfaces. The auto negotiation mechanism and DLDP work together to detect and close unidirectional links on the physical and logical interfaces. If the interfaces on both ends of the link work normally on the physical layer, DLDP checks the connection and packet exchange between the two interfaces on the link layer.

The data VLAN can contain both the RRPP ports and non-RRPP ports. Master node On an Ethernet ring, each switch is called a node.
  • Page 63 Quidway S3700 Series Ethernet Switches Configuration Guide - Reliability 3 RRPP Configuration In the RRPP multi-instance networking, a ring can contain multiple master nodes. Load balancing and link backup can be implemented based on the blocking state of the secondary interface on the master node.
