Stacking
Link Aggregation
The dedicated stacking link is backed up by
a further resiliency link. If the stacking link
fails, communication between the stack
members is maintained to enable graceful
reconfiguration.
Link aggregation to the servers
creates a resilient connection to
important data, providing
load-sharing and high availability.
Link aggregation between the virtual
chassis and edge switches provides full
bandwidth and resiliency and negates the
need to configure spanning tree.

Stack
Stackable edge switches
increase resiliency and
port density, while
providing simplified
management as a single
virtual switch.
All switch tables are
synchronized across the
stack, ensuring no loss of
forwarding information in
the event of a stack
member failing.
