Basic Operations

• Auto-negotiation is enabled on Huawei switch interfaces by default
• The auto-negotiation function allows interfaces on both ends of a link to select the same operating parameters by exchanging capability information.
• Interfaces working at a rate of 1000 Mbit/s only support the full-duplex mode

[Quidway]sysname S1
[S1]display interface GigabitEthernet 0/0/9

• Configuring duplex mode :

auto duplex full

• You can set the interface rate in either the auto-negotiation or non-auto negotiation mode.

  • if two interfaces negotiate to work at a rate of 100 Mbit/s, but they are required to work at a rate of 10 Mbit/s to prevent network traffic congestion, you can run the auto speed 10 command to set the rate of the interfaces to 10 Mbit/s.

  Change Speed

  • undo negotiation auto
  • speed 100

  Create Link aggregation

  interface Eth-Trunk 1
  -> Enable it on all interfaces 
  [S2]interface GigabitEthernet 0/0/10
  [S2-GigabitEthernet0/0/10]eth-trunk 1
  [S2-Eth-Trunk1]quit
  [S2]interface GigabitEthernet 0/0/9
  [S2-GigabitEthernet0/0/9]eth-trunk 1
  

  dis Eth-trunk ->#Display 
  

  Load balancing mode lACP stati

  Create Eth-Trunk 1 and set the load balancing mode of the Eth-Trunk to static LACP mode.

  #global
  [S1]interface Eth-Trunk 1
  [S1-Eth-Trunk1]mode lacp
  [S1-Eth-Trunk1]quit
  
  ##INTEFCE 9
  [S1]interface GigabitEthernet 0/0/9
  [S1-GigabitEthernet0/0/9]eth-trunk 1
  [S1-GigabitEthernet0/0/9]quit
  
  ## interface 10
  [S1]interface GigabitEthernet 0/0/10
  [S1-GigabitEthernet0/0/10]eth-trunk 1
  

  LACP Priority

  Set the system priority on S1 to 100 to ensure S1 remains the Actor.
  [S1]lacp priority 100
  

VLAN

Do all previous without priority

Trunk mode

Step 2 - Establish a VLAN trunk
The link type of a switch port interface is hybrid by default. Configure the port linktype
for Eth-Trunk 1 to become a trunk port. Additionally, allow all VLANS to be
permitted over the trunk port.

[S1]interface Eth-Trunk 1
[S1-Eth-Trunk1]port link-type trunk
[S1-Eth-Trunk1]port trunk allow-pass vlan all

Creating a VLAN
[S1] Vlan 2
[S1] Vlan 3

#configure interfaces 
[S1]interface GigabitEthernet0/0/13
[S1-GigabitEthernet0/0/13]port link-type access
[S2-GigabitEthernet0/0/3]port default vlan 4

#link VLAN to port 
[S1-vlan2]vlan 3
[S1-vlan3]port GigabitEthernet0/0/13

2 Switches sharing a VLAN

[S1-Eth-Trunk1]port trunk pvid vlan 5
[S2-Eth-Trunk1]port trunk pvid vlan 5
