3. VLAN Segmentation & Routing: Supporting multiple VLANs and basic Layer 3 routing between networks.

4. Stacked Network Deployments: Combining multiple switches into a single logical unit for easier management and redundancy.

5. Secure Networks: Enforcing security policies with features like ACLs, MACsec, and DHCP Snooping.

6. High-Bandwidth Connectivity: Providing reliable Gigabit connections to uplinks and critical devices.

Notes & Considerations

• Non‑PoE model: This specific SKU does not provide Power over Ethernet (PoE), so IP phones or Wi‑Fi APs requiring PoE will need external injectors or a PoE switch variant.

• Cisco devices often require Cisco DNA licensing (Essentials/DNA subscriptions) and support contracts for full feature access and software updates. Some resellers list mandatory DNA licenses as an add‑on.

• Pricing varies significantly by region and licensing options, so always request a quote from an authorized Cisco partner.
