![]() ![]() Go to L2 Features > VLAN > 802.1Q VLAN > VLAN Config, create VLAN 10, VLAN 20 and VLAN 30 add Untagged port LAG1 to VLAN 10 add Untagged port LAG2 to VLAN 20 add Untagged port LAG1, LAG2, and port5 to VLAN 30. Then verify the LAGs on the LAG Table page. Go to L2 Features > Switching > LAG > Static LAG, select Group ID as LAG1, select Port 1 and Port 2, click Apply choose then Group ID as LAG2, and select Port 3 and Port 4, click Apply. LAG Configurations on Switch A, Switch B, and Switch C:Įgress Rule and PVID settings for Switch A: With correct PVID settings, both department A and department B can access the internet, but cannot communicate with each other. Create VLAN 30 for the internet, and add the hosts in department A and department B to VLAN 30.Create VLAN 10 and VLAN 20 for department A and department B respectively.Create static LAG1 and LAG2 on switch A, and create static LAG for switch B and switch C respectively.Both department A and department B can access the internet.Hosts in different departments cannot communicate with each other all hosts can access the internet.Users need to improve the bandwidth and redundancy of the link between the switches.Sometimes, we may encounter the application that needs to use these two technologies at the same time here is a configuration example. LAG (Link Aggregation Group) is a technology that can aggregate multiple physical ports into a logical interface, increasing link bandwidth and providing backup ports to enhance the connection reliability. A LAN can be divided into several VLANs logically, and only the hosts in the same VLAN can communicate with each other. VLAN (Virtual Local Area Network) is a technology that can modify the broadcasting domain. ![]()
