How do I enable Link Aggregation on my SB8200 modem?
NOTE: The LAG feature is available on firmware version SB8200.0200.174F.174.311915.NSH.RT.NA and later.

Ethernet Link Aggregation (LAC) combines multiple wired connections (i.e. using two LAN Gigabit Ethernet ports) in parallel to increase throughput beyond what a single connection could sustain.  An important reason for using link aggregation is to provide redundancy in case one of the individual Ethernet ports fails.  This allows client devices (e.g. NAS, Managed network switch, or router) with Ethernet Link Aggregation support to achieve bandwidth up to 2 Gbps (WAN) for wired connections.  The SB8200 LAG feature is disabled by default.  This document contains the following sections:

  • Client device must support LAG.
  • Client device must have LAG enabled and or configured.

The SB8200 LAG feature is available with the fixed (default) settings:  

InterfaceListeth0; eth1

  2. Connect a second Ethernet cable to the WAN/LAG Ethernet port on the router and to Ethernet port 2 on the back of the SB8200 cable modem.
