Using Link Aggregation (LAG) on our 1G Switches

In this process, we are configuring two switches to work together using a Link Aggregation Group (LAG) and the Spanning Tree Protocol (STP), as we do not support Link Aggregation Control Protocol (LACP) on the 1G switch.
 
A Link Aggregation Group (LAG) is a networking technique used to combine multiple network connections in order to increase throughput, provide redundancy, and enhance fault tolerance. It enables two or more physical network links to act as a single logical link. This is achieved by bundling multiple links between the two switches, effectively increasing the bandwidth between them and providing load balancing for the traffic. In this specific case, we are creating a LAG between the Flex 24-10G switch and our 1G switch.
 
Configure the NVT 1G Switch:

1. Access Admin Page:
   Go to the admin page, navigate to the terminal tab.
    
2. Enable Link Aggregation:
   If you are in the GUI, type in the following commands:
   • set-linkagg enable
   • conf-save
     
     Please note that in the CLI Terminal you will need to write "pal-" before those commands
      
3. Show the Configuration:
   • pal-conf-show
      
4. Then look for:

@@@@@ /etc/linkagg
enable=1
 

Configure the Flex-24-10G Switch:
 
FLEX24-10G# configure terminal
FLEX24-10G(config)# interface 10GigabitEthernet 1/1-2
FLEX24-10G(config-if)# aggregation group 1 mode on
FLEX24-10G(config-if)# exit
FLEX24-10G(config)# exit
FLEX24-10G# show aggregation
FLEX24-10G# copy running-config startup-config
