Connectivity options for stacking with FCX and ICX Series devices

You can use stack connections, instead of standard inter-switch links with Layer 2 Spanning Tree

Protocol (STP) or Layer 3 routing, to link distributed switches . Doing so has the following significant

advantages:

• Layer 2 simplicity. Stack links do not need to be considered as part of the overall network topology,

which means that they can be used to provide resiliency, and Layer 3 routing is not needed to

manage traffic flows.

• No shut links. Because the stack links are internal to the switches, they are not seen as part of a

Layer 2 network. This means that all links can remain open and can be used to carry traffic

simultaneously, maximizing throughput.

• Fast failover. Thee rapid detection and recovery techniques used on stack links means that failure

of a link or a switch results in hitless failover with no impact on user services.

• Simplified management. Even when all the switches within a stack are physically distributed, you

can manage them as a single entity, enabling one-touch configuration changes via a single IP

address.
