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.
