Q1: What is the primary difference between Network Essentials and Network Advantage?
A: Network Essentials is designed for standard Layer 2 and Layer 3 access, supporting features like OSPF Routed Access (up to 1,000 routes) and static routing. Network Advantage unlocks full Layer 3 capabilities, including advanced routing protocols like BGP (on certain models), EIGRP, and IS-IS, as well as full SD-Access segmentation features like VRF and VXLAN.
Q2: Does C9200L-48P-4X support StackPower?
A: No: Stacking on C9200L switches is strictly limited to data stacking via StackWise-80; power sharing across switches through StackPower is a feature reserved for higher-tier Catalyst models like the C9300 series.
Q3: Can I stack a C9200L with a modular C9200 switch?
A: No: Mixed stacking is not supported. Fixed models (C9200L SKUs) can only be stacked with other C9200L models that have the same license level.
Q4: How many Wi-Fi 6 APs can this switch power?
A: With the default PWR-C5-1KWAC power supply providing 740W of PoE budget, it can power up to 24 ports at full PoE+ (30W). By adding a second 1KW PSU, the budget increases to 1440W, which is enough to power all 48 ports at 30W simultaneously.
Q5: What is the purpose of Perpetual PoE?
A: Perpetual PoE ensures that PoE+ power delivery to endpoints, such as IP cameras or medical devices, is maintained even during a switch reload. This prevents critical services from being interrupted during a reboot.
Q6: Are the fans on this model field-replaceable?
A: No: On the C9200L fixed SKUs, the fan units are fixed and cannot be replaced in the field. If you require field-replaceable (FRU) fan modules, you should consider the modular C9200 series.
Q7: Can I use 1G SFP modules in the 10G uplink ports?
A: Yes: The four fixed uplink ports are dual-speed, supporting both 1G SFP and 10G SFP+ transceivers. This provides investment protection as your backbone bandwidth needs grow.
Q8: What is the packet forwarding performance of the C9200L-48P-4X?
A: In a standalone configuration, this model provides a forwarding rate of 130.95 Mpps. When configured in a stack, the combined forwarding rate can reach up to 190 Mpps.
Q9: How many Virtual Networks (VNs) are supported for SD-Access?
A: The C9200L series supports a limited SD-Access implementation, allowing only 1 Virtual Network. For deployments requiring higher scale multi-tenancy, the modular C9200 series is required.
Q10: What is the total stacking bandwidth available for this model?
A: The C9200L series supports StackWise-80, providing a total stacking bandwidth of 80 Gbps. This is compared to the 160 Gbps supported by the modular C9200 series.
Q11: Does the C9200L-48P-4X support MACsec encryption?
A: Yes: It supports AES-128 MACsec encryption, which provides hardware-level link-layer security for data flowing through the switch.
Q12: Can I monitor this switch through a cloud-based dashboard?
A: Yes: The Catalyst 9200 series supports cloud monitoring through the Meraki dashboard, allowing you to view switch statistics, configuration, and troubleshooting data remotely.
Q13: What is the maximum number of MAC addresses this switch can handle?
A: The C9200L series has a capacity for a total of 16,000 MAC address entries.
Q14: Is this switch certified for environmental energy efficiency?
A: Yes: The C9200L models are ENERGY STAR certified and support Energy Efficient Ethernet (EEE) to minimize power consumption on ports that are not in use.
Q15: How many switches can I include in a single logical stack?
A: You can stack up to 8 switches in a single logical unit using StackWise-80, which allows you to manage up to 384 access ports through a single management plane.
