Huawei switch network cable access

To access a Huawei switch via network cables, connect the appropriate Ethernet or optical cable, configure the port as an access port, assign it to a VLAN, and enable it using CLI commands.

Physical Cable Connection
  • Ethernet Cables: Use CAT5E or CAT6 cables for standard connections, but avoid using them for 5GE or 10GE interfaces due to potential crosstalk and packet loss issues. If the cable does not meet standards, either replace it or reduce the interface speed .
  • Optical Fiber: Install an optical module on the SFP+ port if required, and connect to the peer device using optical fiber. Ensure the fiber bend radius does not exceed 180° and remove dust plugs before installation .
  • PoE Considerations: If using PoE, ensure the power supply type is compatible. Both Ethernet ports support PoE input, and power is superimposed if the types are the same .
  • Cable Management: Bundle cables neatly, maintain at least 30 mm spacing between different types, and create drip loops to prevent water ingress .
Configuring Access Ports
  1. Access the Switch CLI: Connect via console cable or SSH and log in. Enter system-view mode using system-view .
  2. Select the Port: Navigate to the target port, e.g., interface GigabitEthernet 0/0/1 .
  3. Set Port Type: Configure the port as an access port with port link-type access .
  4. Assign VLAN: Assign the port to a VLAN using port default vlan 10 (replace 10 with your VLAN ID), .
  5. Enable the Port: Activate the port with undo shutdown .
  6. Save Configuration: Use save to make changes permanent .
Security and Optimization
  • Port Security: Enable MAC address binding with port-security enable and port-security mac-address sticky to prevent unauthorized devices .
  • Rate Limiting: Apply outbound rate limits using qos lr outbound cir to control traffic .
  • Verification: Check port status with display interface GigabitEthernet0/0/1 and VLAN assignment with display vlan .
Additional Notes
  • For trunk ports, use port link-type trunk and allow VLANs with port trunk allow-pass vlan all .
  • For switches supporting auto-negotiation, enable rate decrease auto-negotiation to adjust speed based on cable quality .
  • Always follow ESD protection measures when handling ports and modules .

By following these steps, you can ensure proper network cable access, secure port configuration, and reliable connectivity on Huawei switches.
