Okay, found the following Info. It clearly states dynamic ling aggregation for the 802.3ad protocol and thus the dlink static trunk would not work on this selection but it may on options e and f..
Above my pay grade.......................
The way I understand the following selections
a. load balance - based solely on availability of switch ie taking turns
b. failover - only one active at a time auto fail over
c. balance xor - I think very tentatively this means each port on the nAS is slaved to a port on the switch by mac address. the nas applies load balancing as per a. and fault tolerance since both are always up.
d. 802.3ad - has to be on both switch and NAS. dynamically creates one big throughput and of course fault tolerance. BEST bonding performance.
e. balance tlb - beyond me BUT SEEMS to indicate this may work with STATIC TRUNK.
f. balance alb - beyond me BUT may work well with STATIC TRUNKs
Load Balance (mode=0, balance-rr)
Round-robin policy: Transmit packets in sequential order from the first available slave through the last. This mode provides load balancing and fault tolerance.
Failover (mode=1, active-backup)
Active-backup policy: Only one slave in the bond is active. A different slave becomes active if, and only if, the active slave fails. The bond's MAC address is externally visible on only one port (network adapter) to avoid confusing the switch. This mode provides fault tolerance. The primary option affects the behavior of this mode.
Balance-XOR (mode=2, balance-xor)
XOR policy: Transmit based on [(source MAC address XOR'd with destination MAC address) modulo slave count]. This selects the same slave for each destination MAC address. This mode provides load balancing and fault tolerance.
802.3ad (mode=4, 802.3ad)
IEEE 802.3ad Dynamic link aggregation. Creates aggregation groups that share the same speed and duplex settings. Utilizes all slaves in the active aggregator according to the 802.3ad specification.
1. Ethtool support in the base drivers for retrieving the speed and duplex of each slave.
2. A switch that supports IEEE 802.3ad Dynamic link aggregation.
Most switches will require some type of configuration to enable 802.3ad mode.
Balance-TLB (mode=5, balance-tlb)
Adaptive transmit load balancing: channel bonding that does not require any special switch support. The outgoing traffic is distributed according to the current load (computed relative to the speed) on each slave. Incoming traffic is received by the current slave. If the receiving slave fails, another slave takes over the MAC address of the failed receiving slave.
Prerequisite: Ethtool support in the base drivers for retrieving the speed of each slave.
Balance-ALB (mode=6, balance-alb)
Adaptive load balancing: includes balance-tlb plus receive load balancing (rlb) for IPV4 traffic, and does not require any special switch support. The receive load balancing is achieved by ARP negotiation. The bonding driver intercepts the ARP Replies sent by the local system on their way out and overwrites the source hardware address with the unique hardware address of one of the slaves in the bond such that different peers use different hardware addresses for the server.
For example, if you want to setup 802.3ad, just enable the option "802.3ad", and connect both WAN and LAN to your switch. Be sure your switch supports 802.3ad, or it may not work.--
