Cisco C9300L-STACK-KIT | Stacking Kit, StackWise-320, 2x Adapters, 0.5m Cable

Q: Which Catalyst 9300 switches are compatible with this stacking kit?
A: The C9300L-STACK-KIT is designed exclusively for Catalyst 9300L and C9300LM Series fixed uplink models. It is not compatible with C9300 modular uplink models, which have built-in stacking ports and do not require stack adapters.

Q: How many switches can be stacked with this kit?
A: Up to 8 Catalyst 9300L switches can be stacked in a ring topology using StackWise-320 technology, providing a unified management plane and control plane with 320 Gbps of stacking bandwidth across the stack.

Q: Do I need to purchase a stacking kit for every switch in the stack?
A: Yes, each Catalyst 9300L switch requires its own stack kit (two adapters per switch). You will also need one stacking cable per inter-switch connection. For example, a 4-switch ring requires 4 stack kits and 4 stacking cables total.

Q: Can I use longer stacking cables if my switches are not mounted adjacently?
A: Yes, the default kit includes a 0.5-meter cable, but Cisco offers 1-meter and 3-meter stacking cables as separate orderable items to accommodate different rack configurations and physical layouts.

Q: What are the benefits of stacking Catalyst 9300L switches?
A: Stacking provides simplified management with a single IP address and management interface for the entire stack, high availability through redundant control planes, scalability up to 448 access ports, and non-stop forwarding with Stateful Switchover for network resilience.
