Redundant Switch Failover; Pci Hot Plug - Allied Telesis AT-2400 Series Installation Manual

Redundant
Switch Failover

PCI Hot Plug

Beyond the features required for link aggregation in the IEEE 802.3ad
(LACP) standard, the AT-2916T and AT-297x supports an additional
failover feature, the so-called Redundant Switch Failover (RSF). If a
switch fails completely, RSF can move the link to a different with which
then takes over the traffic.
At the moment, this feature is implemented in the driver package for
Windows 2000 and Windows XP. The standard requires that all links of a
link aggregation group (team) are connected to the same partner
(usually a switch supporting 802.3ad (LACP)). With Allied Telesyn's link
aggregation driver, one team (group of logical links) can comprise of
several aggregators, which are connected to separated switches, the
failover feature is utilized. Data is transferred via one aggregator, and is,
if this aggregator fails, automatically switched over to another
aggregator in the same team.
Hot Plug enables the replacement of failed devices in a running system.
