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.
