What Are the Network Requirements for Connections?

  • Your on-premises network must use a single-mode fiber with a 1GE, 10GE, 40GE, or 100GE optical module to connect to the access device in Huawei Cloud. In addition, key parameters such as the LC, wavelength, and distance must be consistent with those of the access device on Huawei Cloud. Examples of optical module parameters: 1 GE, LC single-mode, 1,310 nm, and 10 km
  • Auto-negotiation for the port must be disabled. Port speed and full-duplex mode must be manually configured.
  • 802.1Q VLAN encapsulation must be supported on all devices of the entire connection, including intermediate devices.
  • Your device must support Border Gateway Protocol (BGP) and BGP MD5 authentication or static routing.
  • (Optional) You can configure Bidirectional Forwarding Detection (BFD) on the network.
  • A physical connection supports jumbo frames with a default maximum transmission unit (MTU) size of 8,500 bytes. If you need to configure a larger MTU, contact the Direct Connect manager.

    If you ping the IP address of the local gateway of a Direct Connect connection for connectivity test, the MTU is 1,500 bytes.

  • Private IP addresses are recommended for cloud and on-premises servers, and the IP address ranges used for communications cannot overlap.
