Q1: What exactly does "PXG" mean in the C9200L-48PXG-2Y-A model name?
A: "PXG" indicates a high-density Multigigabit (mGig) PoE+ switch. It includes 48 ports, with 8 multigigabit ports capable of up to 10G speeds and 40 standard 1G PoE+ ports.
Q2: Why is the 12 MB packet buffer important for this specific switch?
A: The 12 MB packet buffer helps absorb traffic bursts from high-throughput Wi-Fi 6/6E access points, reducing packet loss and maintaining low latency for stable video and voice performance.
Q3: What routing protocols are unlocked with the Network Advantage license?
A: The Network Advantage license enables full enterprise routing, including EIGRP, IS-IS, full OSPF, and advanced multicast features such as BSR and MSDP.
Q4: Does the C9200L-48PXG-2Y-A support multiple Virtual Networks for SD-Access?
A: No. All fixed C9200L models support only one Virtual Network for SD-Access, even with the Advantage license. Modular C9200 models are required for multiple Virtual Networks.
Q5: What is the advantage of the 225G uplinks (-2Y)?
A: The two 25G SFP28 uplinks provide high aggregation bandwidth to prevent congestion from multiple downstream devices, and they support 1G and 10G for backward compatibility.
Q6: How much PoE power can this switch deliver?
A: It includes a 1000W AC power supply providing a 740W PoE+ budget. Adding a second power supply increases total PoE capacity to 1440W.
Q7: Are the cooling fans and power supplies field-replaceable?
A: Power supplies are field-replaceable and support redundancy, but the cooling fans are built into the chassis and are not field-replaceable.
Q8: Does this switch support BGP routing?
A: No. BGP is not supported on Catalyst 9200L series switches; it is available only on compact C9200CX models.
Q9: Can I stack this switch with other Catalyst models?
A: Yes. With the optional C9200L-STACK-KIT, you can stack up to 8 switches using StackWise-80 with 80 Gbps bandwidth and unified management.
Q10: Why do IT channel partners frequently stock this high-end model in physical stores?
A: It combines advanced routing, segmentation, high-density PoE+, and multigigabit capability, making it a versatile and future-ready solution for enterprise deployments.
Q11: What warranty is included?
A: It is covered by the Cisco Enhanced Limited Lifetime Warranty (E-LLW), including next-business-day hardware replacement where available and 90 days of 85 TAC support.
