What Are the Network Requirements for Connections?
Updated on 2025-01-22 GMT+08:00
- 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 aligned with the Direct Connect location you select, for example, 1GE, LC, single-mode, 1310nm, 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 BGP and BGP MD5 authentication or static routing.
- (Optional) You can configure BFD on your network.
- The maximum transmission unit (MTU) supported at the physical layer cannot exceed 1,522 bytes (including 14-byte Ethernet header, 4-byte VLAN tag, 1,500-byte IP datagram, and 4-byte frame check sequence). The recommended value is 1,500.
- Private IP addresses are recommended for cloud and on-premises servers, and the IP address ranges used for communications cannot overlap.
