Cisco Catalyst C1000-24P-4G-L 24-Port Managed PoE+ Switch, 4x1G SFP
The Cisco Catalyst C1000-24P-4G-L is a 24-port PoE+ Layer 2 managed switch with 4x 1G SFP uplinks. It delivers 195W of PoE and supports Single IP Management.
Overview
The Cisco Catalyst 1000 Series is Cisco's line of fixed managed enterprise-class Layer 2 switches for small business and branch networks, running Cisco IOS with both a command-line interface and an on-box web UI so they can be deployed out of the wiring closet and into IoT-heavy sites. The C1000-24P-4G-L is the 24-port PoE+ configuration with four fixed 1G SFP uplinks. Its 1G SFP uplinks aggregate access traffic back to the distribution layer over fiber or copper. PoE+ on the access ports powers a mix of wireless access points, IP phones, and cameras from the switch itself on a partial power budget. As a Gigabit Ethernet model it supports Cisco Single IP Management for administering up to eight switches under one IP address, along with Cisco IOS capabilities such as AutoConfig for touchless provisioning and Bluetooth-based local console access.
Technical Details
The Cisco Catalyst C1000-24P-4G-L is a Layer 2 managed 1U rackmount access switch with 24 Gigabit Ethernet (10/100/1000) PoE+ ports and four fixed 1G SFP uplinks, running Cisco IOS. Switching capacity is 56 Gbps and forwarding rate is 41.67 Mpps. It delivers PoE+ (IEEE 802.3af and 802.3at) from a 195 W PoE power budget shared across the access ports. It provides wired access-layer connectivity and PoE+ power for endpoints such as wireless access points, IP phones, and IP cameras in small business and branch wiring closets.

Branch Office
Best For
The Cisco Catalyst C1000-24P-4G-L suits small business and branch wiring closets that power a moderate mix of access points, IP phones, and IP cameras while aggregating traffic over 1-Gigabit fiber or copper uplinks. A 195 W PoE+ budget is suitable for mixed deployments of these powered devices; actual device counts depend on each device's power draw. It runs a single fixed Cisco IOS Layer 2 feature set with no license tiers to select.
Not suitable if:
- you need 10G uplinks, since this model has fixed 1G SFP uplinks
- you need Layer 3 routing between VLANs or dynamic routing protocols, since the Catalyst 1000 is a Layer 2-only switch
- you need multigigabit (mGig) access ports, since all access ports run at 10/100/1000
- you need more than 24 access ports in a single unit

FAQ
Does the Cisco Catalyst C1000-24P-4G-L support PoE+, and what is the power budget?
Yes. The Cisco Catalyst C1000-24P-4G-L provides PoE+ (IEEE 802.3af and 802.3at) on all 24 Gigabit Ethernet access ports, drawing from a 195 W system PoE power budget shared across the ports. This supports mixed deployments of powered devices such as wireless access points, IP phones, and IP cameras; the number of devices depends on each device's power draw. For a higher shared PoE budget that supports denser powered-device deployments, the Cisco Catalyst C1000-24FP-4G-L provides Full PoE+.
What transceivers do the uplinks on the C1000-24P-4G-L use?
The Cisco Catalyst C1000-24P-4G-L has four fixed 1G SFP uplink ports. These are 1-Gigabit SFP slots and do not accept 10G SFP+ optics. Specific transceiver compatibility should be verified against the manufacturer's transceiver compatibility matrix at tmgmatrix.cisco.com. Transceivers are sold separately.
Can the Cisco Catalyst C1000-24P-4G-L be stacked?
The Cisco Catalyst C1000-24P-4G-L does not support data-plane stacking; there is no shared switching fabric across units. As a Gigabit Ethernet model it does support Cisco Single IP Management, which lets up to eight Catalyst 1000 switches be connected through their uplink ports and managed under a single IP address. This is a management convenience for administering several switches together, not a high-bandwidth stacking backplane, so each switch forwards traffic independently.
What is the difference between the C1000-24P-4G-L and the C1000-24FP-4G-L?
Both are 24-port Gigabit Ethernet Layer 2 switches with the same four 1G SFP uplinks and 56 Gbps switching capacity, and both provide PoE+. They differ in PoE power budget: the C1000-24P-4G-L has a 195 W budget for mixed powered-device deployments, while the C1000-24FP-4G-L has a 370 W Full PoE+ budget that supports denser powered-device deployments. On both, all access ports support PoE+ up to 30W per port, subject to the shared total PoE budget. Choose the FP model for dense access-point or camera deployments; actual device counts depend on each device's power draw.
What is the difference between the C1000-24P-4G-L and the C1000-24P-4X-L?
Both are 24-port PoE+ Gigabit Ethernet Layer 2 switches with a 195 W PoE budget, and they differ in uplink speed. The C1000-24P-4G-L has four fixed 1G SFP uplinks and 56 Gbps of switching capacity, while the C1000-24P-4X-L has four fixed 10G SFP+ uplinks and 128 Gbps of switching capacity. Choose the C1000-24P-4X-L when the access layer needs 10-Gigabit fiber uplinks to the distribution layer.
Does the Cisco Catalyst C1000-24P-4G-L support Layer 3 routing?
No. The Cisco Catalyst C1000-24P-4G-L is a Layer 2 managed switch and does not provide dynamic Layer 3 routing. It runs Cisco IOS with Layer 2 features such as VLANs, spanning tree, and quality of service, and it is designed for the access layer. Networks that need routing between VLANs or dynamic routing protocols should place a Layer 3 switch or router at the distribution layer.
Is the Cisco Catalyst C1000-24P-4G-L end of life?
Cisco has published an End-of-Sale and End-of-Life notice for the Cisco Catalyst 1000 Series. The last date for Cisco to accept new orders was April 30, 2025, and the Last Date of Support is April 30, 2030. Network Devices Inc. sells new, factory-sealed Catalyst 1000 units from inventory, and Cisco support continues under active service contracts through the Last Date of Support. The C1000-24P-4G-L remains fully supportable for deployments planned within that window.
What condition is the C1000-24P-4G-L sold in, and what warranty applies?
The Cisco Catalyst C1000-24P-4G-L is sold new and factory-sealed. It is covered by a Network Devices Inc. one-year warranty and a 30-day return policy.
