This tutorial will help you to trunk your ports via Link Aggregation!
Walkthrough Steps
This tutorial will show you how to configure an 802.3ad LACP interface that bundles multiple physical ports of your USG to multiply the bandwidth or to create a balance-alb interface that connects a specific VLAN from multiple USG ports to multiple switches:
1. Configuration of 802.3ad (LACP Mode)
- Log in to the unit by entering it's IP address and the credentials for an admin account (by default, username is “admin”, password is “1234”)
- Navigate to Network > Interface > LAG and add a new interface under “Configuration”
- Tick the “Enable Interface” checkbox, set the “Interface Type” to “Internal”, type in a name and choose the appropriate security “Zone”
- Scroll down to “LAG Configuration”, change the “Mode” to “802.3ad”, change the “Xmit Hash Policy” to “layer 2” to connect a Layer 2 switch, or to “layer2+3” to connect to a router or Layer 3 switch
- Choose the desired “LACP rate” to fast (every second) or slow (every 30 seconds).
Choose the desired ports to be a member of your LAG.
Scroll down to “IP Address Assignment” and “DHCP Setting” to configure the IP and DHCP settings of your LAG interface before finally clicking “OK”
2. Configuration of balance-alb mode
- Log in to the unit by entering its IP address and the credentials for an admin account (by default, the username is “admin”, the password is “1234”)
- Navigate to Network > Interface > LAG and add a new interface under “Configuration”
- Tick the “Enable Interface” checkbox, set the “Interface Type” to “Internal”, type in a name and choose the appropriate security “Zone”
- Scroll down to “LAG Configuration”, change the “Mode” to “balance-alb”
- Choose the desired ports to be a member of your LAG.
Scroll down to “IP Address Assignment” and “DHCP Setting” to configure the IP and DHCP settings of your LAG interface before finally clicking “OK” - To share the VLAN using multiple USG ports across multiple switches, please click on the tab “VLAN”, edit the desired VLAN and choose the LAG Interface as your “Base Port”
Please note: When configuring 802.3ad (LACP), you also have to configure the switch ports to be in a matching link aggregation.
You can only use one switch but multiple switch ports.
The port speed and duplex must be the same on the switch and USG ports.
Be careful when configuring Link Aggregation! Misconfiguration might lead to loops that could break down your network.
