10.11 LAG
Link Aggregation Group (LAG) is a way to combine multiple physical Ethernet interfaces into a single
logical interface. This increases uplink bandwidth. It also increases availability as even if a member link
goes down, LAG can continue to transmit and receive traffic over the remaining links.
To configure LAG, configure a link number and specify the member ports in the link. All ports must have
the same speed and be in full-duplex mode. You must configure the LAG on both sides of the link and
you must set the interfaces on either side of the link to be the same speed.
At the time of writing, up to 4 ports can be grouped into a LAG and up to 4 LAGs can be configured on
a Zyxel Device.
See Section 1.1 on page 28 to see which models support Link Aggregation Group (LAG).
10.11.1 LAG Summary Screen
This screen lists every LAG created on the Zyxel Device. To access this screen, click Configuration >
Network > Interface > LAG.
Add Click Add to create an IPv4 Address, an IPv4 CIDR (for example, 192.168.1.1/24) or an IPv4
Range (for example, 192.168.1.2-192.168.1.100) as the target IP address. The Zyxel Device
answers external ARP requests only if they match one of these inputted target IP addresses.
For example, if the IPv4 Address is 192.168.1.5, then the Zyxel Device will answer ARP
requests coming from the WAN only if it contains 192.168.1.5 as the target IP address.
