The two devices at both ends of link aggregation must be in the same stacking system. This mode requires that the port on the peer device (CX320) must be configured with link aggregation that complies with IEEE 802.3ad. If you enable jumbo frames on your network you’ll get closer to 1.9gbps but you’ll need to have a dedicated network segment with devices that use jumbo frames and a router in between to fragment them for the lower MTU devices. Set the bonding mode to 802.3ad, that is, the link aggregation mode complying with IEEE802.3ad. With the above you’ll get around 1600mbps due to tcp retransmission overheads due to packet reordering but it’s still a great performance bump for single client single transfer scenarios. The network card can have No IP Address (which is useful for bonding devices), a Statically Assigned IP Address. 802.3ad True bonding which aggregates the bandwidth of multiple interfaces. Set the bonding mode to 802.3ad, that is, the link aggregation mode complying with IEEE802.3ad. Both IPv4 and IPv6 addresses are supported. The IP addresses of the NIC team ports are 192.168.20.40/24 and belongs to VLAN 20. Setting the MODE in the netctl configuration is not always successful and it may be necessary to pass options directly to the bonding module on load as noted here. File to edit is /etc/sysconfig/network-scripts/ifcfg-bond0 and change the option BONDING_OPTS="mode=4 to 0 while leaving the rest of the line as is. Port1 and Port0 are configured as a NIC team, using the 802.3ad mode. You’ll need to edit a config file on the Synology NAS as that option is not present in the gui. Set the bonding mode to balance-rr on both sides. The “trick” for improved single client single transfer performance is:ģ. Link Aggregation Control Protocol (LACP) is a subcomponent of the IEEE 802.3ad. Also using link aggregation to my VM box again using 2 ports in the same switch. Load balancing will not work if you configure link speeds that are not supported. I’m using static link aggregation with my 1019+.
