Generic Trunking (FEC/GEC)/802.3ad-Draft Static
The Generic Trunking (FEC/GEC)/802.3ad-Draft Static type of team is very similar
to the Link Aggregation (802.3ad) type of team in that all adapters in the team are
configured to receive packets for the same MAC address. The Generic Trunking
(FEC/GEC)/802.3ad-Draft Static) type of team, however, does not provide LACP
or marker protocol support. This type of team supports a variety of environments
in which the adapter link partners are statically configured to support a proprietary
trunking mechanism. For instance, this type of team could be used to support
Lucent’s OpenTrunk or Cisco’s Fast EtherChannel (FEC). Basically, this type of
team is a light version of the Link Aggregation (802.3ad) type of team. This
approach is much simpler, in that there is not a formalized link aggregation control
protocol (LACP). As with the other types of teams, the creation of teams and the
allocation of physical adapters to various teams is done statically through user
configuration software.
The Generic Trunking (FEC/GEC/802.3ad-Draft Static) type of team supports load
balancing and failover for both outbound and inbound traffic.
SLB (Auto-Fallback Disable)
The SLB (Auto-Fallback Disable) type of team is identical to the Smart Load
Balancing and Failover type of team, with the following exception—when the
standby member is active, if a primary member comes back on line, the team
continues using the standby member, rather than switching back to the primary
member.
All primary interfaces in a team participate in load-balancing operations by
sending and receiving a portion of the total traffic. Standby interfaces take over
when all primary interfaces have lost their links.
Failover teaming provides redundant adapter operation (fault tolerance) when a
network connection fails. If the primary adapter in a team is disconnected because
of failure of the adapter, cable, or switch port, the secondary team member
becomes active, redirecting both inbound and outbound traffic originally assigned
to the primary adapter. Sessions will be maintained, causing no impact to the user.
NOTE
Generic Trunk (FEC/GEC/802.3ad Draft Static) team type is not supported
for ports with NPAR mode or FCoE-Offload or iSCSI-Offload enabled.
