1. What is Port LAG and the purpose of this feature?
– Port LAG (Link Aggregation) is a method of adding 2 or more network ports together, forming a single connection equal to the total bandwidth of participating ports or to prevent errors.
– Port LAG with trunking feature will increase connection speed beyond the limit of a single link or individual network port.
– Enhances actual transmission performance to create stability in the server environment, diversifying connections from clients.
– The redundancy feature also creates greater availability and prevents transmission interruptions.
2. Configuration:
– Log into the Sophos XG Web GUI page with an account with admin rights.
– Select Network > Interfaces > Add Interfaces > Add LAG and fill in the following parameters:
– Interface name: name this LAG port.
