Q1: Does the C9200L-48T-4X support full Layer 3 routing?
A: Yes. With Network Essentials, it supports static routing, RIP, and OSPF Routed Access (up to 1,000 routes). For full-scale routing including EIGRP, BGP, and IS-IS, the Network Advantage license is required.
Q2: Is this switch suitable for Wi-Fi 6 or Wi-Fi 6E deployments?
A: While the 48T model is non-PoE and cannot power APs directly, its 4x10G SFP+ uplinks provide high-speed backhaul, making it an excellent aggregation switch for wireless infrastructure.
Q3: What are the primary benefits of choosing the 48T (Data) over the 48P (PoE) model?
A: The 48T model offers a significantly higher MTBF (503,400 hours vs 346,270 hours), lower power consumption, and a lighter chassis (4.53 kg), providing a more cost-effective and reliable solution for wired-only environments.
Q4: Can I stack different Cisco Catalyst series switches together?
A: No. Mixed stacking is not supported. C9200L models can only be stacked with other C9200L models of the same license level.
Q5: What is the maximum number of devices supported in the MAC address table?
A: The C9200L series supports up to 16,000 MAC address entries, which is optimized for medium to large-scale enterprise access networks.
Q6: Are the fan modules field-replaceable in the C9200L-48T-4X?
A: No. The fans on C9200L fixed models are redundant but fixed. If your environment requires field-replaceable (FRU) fan units, the modular C9200 series should be considered.
Q7: Does this switch support hardware-level data encryption?
A: Yes. It supports hardware-anchored AES-128 MACsec encryption, ensuring secure data transmission and mitigating man-in-the-middle attacks.
Q8: Can the C9200L-48T-4X be powered by redundant power supplies?
A: Yes. It supports dual field-replaceable power supplies. You can add a second PWR-C5-125WAC unit to achieve 1+1 redundancy for business continuity.
Q9: What management options are available for this switch?
A: You can manage it via traditional CLI, Cisco Catalyst Center (on-premises), WebUI (embedded), or Meraki cloud monitoring for Catalyst.
Q10: Does it support SD-Access segmentation features?
A: Yes, with the Network Advantage license, it supports VRF, VXLAN, LISP, and SGT (Security Group Tags) for secure network segmentation.
Q11: What is the total stacking bandwidth for the C9200L series?
A: It uses StackWise-80 technology, providing 80 Gbps of bidirectional stacking bandwidth for up to 8 switches in a single logical unit.
Q12: Is the C9200L-48T-4X environmentally friendly?
A: Yes. It is ENERGY STAR certified and supports IEEE 802.3az Energy Efficient Ethernet (EEE) to reduce power consumption during idle periods.
Q13: How many VLANs can be configured on this switch?
A: It supports up to 4,096 VLAN IDs.
Q14: Does it support modern automation APIs?
A: Yes. It runs Cisco IOS XE, which supports open APIs over NETCONF and RESTCONF using YANG data models for automated provisioning.
Q15: What is the benefit of the UADP 2.0 Mini ASIC?
A: The UADP ASIC provides a programmable pipeline, ensuring investment protection by allowing the switch to support future innovations and protocols through software updates.
