Introduction

Manual mode Eth-Trunk is a technology based on Ethernet Link Aggregation (LAG) to realize multiple physical links into one large logical link with fault tolerance and load balancing characteristics. In manual mode, the administrator needs to manually configure the member ports of each physical link and the parameters of the Eth-Trunk interface, such as Eth-Trunk ID, load balancing algorithm, link monitoring method, etc.

Configuring manual mode Eth-Trunk mainly requires the following steps:

  1. Create an Eth-Trunk interface and configure the Eth-Trunk ID.

  2. Configure the member ports of each physical link, and specify parameters such as member priority and link monitoring mode.

  3. Configure the load balancing algorithm parameters of the Eth-Trunk interface to implement the load balancing function.

  4. Finally, the administrator needs to verify the correctness of the configuration to ensure that the Eth-Trunk interface can work properly.

In practical applications, manual mode Eth-Trunk is often used to build a high-availability network architecture to achieve load balancing and link fault tolerance.

2.1 Network diagram for configuring Eth-Trunk in manual mode

2.2 Create Eth-Trunk1 on SW1 and SW2 respectively and configure it in manual mode.

# Configure SW1

system-view //Enter system view
Undo info-center enable //Close the information management center
sysname SW1 //Name the switch SW1
interface Eth-Trunk 1 //Create Eth-Trunk interface 1 and enter the Eth-Trunk interface view
Portswitch //Switch the Eth-Trunk interface to Layer 2 mode
mode manual load-balance //The mode is manual mode Eth-Trunk, manual means manual, and load-blance means load balancing.

# Configure SW2

system-view
Undo info-center enable
sysname SW2
interface Eth-Trunk 1
portswitch
mode manual load-balance

2.3 Add member interfaces to the Eth-Trunk interfaces of SW1 and SW2.

# Configure SW1

trunkport GigabitEthernet 0/0/1 to 0/0/3
quit

# Configure SW2

trunkport GigabitEthernet 0/0/1 to 0/0/3
quit

2.4 Save configuration

Save
Y
Enter

2.5 Check configuration results

Run the display eth-trunk 1 command in any view on SW1 and SW2 respectively to check whether the Eth-Trunk is created successfully and whether the member interfaces are correctly added.

2.6 Configuration Script

# Configure SW1

system-view
Undo info-center enable
sysname SW1
interface Eth-Trunk 1
portswitch
mode manual load-balance
trunkport GigabitEthernet 0/0/1 to 0/0/3
Quit
quit
save

# Configure SW2

system-view
Undo info-center enable
sysname SW2
interface Eth-Trunk 1
portswitch
mode manual load-balance
trunkport GigabitEthernet 0/0/1 to 0/0/3
Quit
Quit
save

3. Experience and experience

In my opinion, configuring manual mode Eth-Trunk requires certain network knowledge and experience to be completed successfully. The following are some of my experiences:

  1. Familiar with the principles and functions of link aggregation technology, and understanding the roles, advantages and disadvantages of different load balancing algorithms and link monitoring methods, you can better choose the appropriate configuration.

  2. Understand the hardware specifications and limitations of network equipment, and rationally plan the number and speed of Eth-Trunk member ports to avoid bottlenecks or redundant ports.

  3. In practical applications, monitoring and maintenance work need to be done, and load balancing algorithms and link monitoring methods need to be adjusted in a timely manner to ensure the availability and stability of the Eth-Trunk interface.

In general, configuring a manual mode Eth-Trunk is a relatively complex and technically demanding task that requires adequate planning and preparation, as well as careful implementation and monitoring. However, once configured successfully, it can provide high availability and load balancing functions for the network, improving network stability and performance.
