Link Aggregation for GS308E

The operating modes for LAGG interfaces are: LACP, Failover, Load Balance, Round Robin, and None.

LACP

The most commonly used LAGG protocol. ---> borrowed this text from the pfsense software, derived from FreeBSD. in the Netgear plus switch context, only Load Balance and Round Robin are meaningful. LACP isn't available <---

Failover

When using the Failover LAGG protocol traffic will only be sent on the primary interface of the group. If the primary interface fails, then traffic will use the next available interface.

Note

By default, traffic may only be received by the active interface. Create a system tunable for net.link.lagg.failover_rx_all with a value of 1 to allow traffic to be received on every member interface.

Failover mode has one additional option:

Failover Primary Interface

This option sets the primary interface for failover mode, or auto to allow the firewall to select the primary interface automatically. In auto mode, the first selected interface in the list is primary.

Each non-primary interface is eligible for use in failover if the primary fails.

Load Balance

Load Balance mode accepts inbound traffic on any port of the LAGG group and balances outgoing traffic on any active ports in the LAGG group. It is a static setup that does not monitor the link state nor does it negotiate with the switch. Outbound traffic is load balanced based on all active ports in the LAGG using a hash computed using several factors, such as the source and destination IP address, MAC address, and VLAN tag.

Round Robin

This mode accepts inbound traffic on any port of the LAGG group and sends outbound traffic using a round robin scheduling algorithm. Typically this means that traffic will be sent out in sequence, using each interface in the group in turn.

None

This mode disables traffic on the LAGG interface without disabling the interface itself. The OS will still believe the interface is up and usable, but no traffic will be sent or received on the group.

Description

A short note about the purpose of this LAGG instance.

LAGG Interface Configuration

To create or manage LAGG interfaces:

• Navigate to Interfaces > Assignments, LAGGs tab

• Click 

   

   

   Add to create a new LAGG, or click 

   

   

   to edit an existing instance.

• Complete the settings as described in LAGG Interface Settings

• Click Save

  After creating a LAGG interface, it works like any other physical interface. Assign the lagg interface under Interfaces > Assignments and give it an IP address, or build other things on top of it such as VLANs.
