Link Aggregation, also known as port trunking, is a method of combining multiple physical network connections into one logical link to increase bandwidth and provide redundancy in case one of the links fails.

On the GS1200 series switch, you would use Link Aggregation to utilize multiple lower-speed links to achieve a higher cumulative speed at a lower cost than using a single high-speed connection.

Configuration

Navigate to the 'Link Aggregation' tab

Step 1: Set the Link Aggregation Algorithm: It determines how outgoing traffic is distributed across the aggregated links. Choose the traffic distribution type:

  1. MAC SA & DA: Default setting that takes both source and destination MAC addresses to distribute traffic.
  2. MAC SA: Distributes traffic based solely on the packet's source MAC address.
  3. MAC DA: Distributes traffic based on the packet's destination MAC address.

Step 2: Define Link Aggregation Group:

  • Identify and select the ports you wish to include in the aggregation.
  • Note that specific models have predefined groups:
    • GS1200-5 and GS1200-5HP: Link aggregation group containing ports 3 and 4.
    • GS1200-8 and GS1200-8HP: Two groups available, one containing ports 3 and 4, and another with ports 7 and 8.

Step 3: Click the 'Apply' button to save your changes.

Note

  • Ensure all ports in a link aggregation group have the same PVID and VLAN ID.
  • Cannot configure port isolation settings and link aggregation settings on the same port.
