WS-C2950-12 is a managed Layer 2 workgroup switch with twelve 10/100 Mbps copper access ports, a fixed configuration, and no dedicated uplink ports. The non-PoE design connects independently powered endpoints rather than supplying power through Ethernet cabling. Cisco Catalyst 2950 Series hardware occupies a full-width 1U rack position and uses Standard Image software for basic data, voice, and video connectivity in small-business networks. The discontinued WS-C2950-24 carries twenty-four access ports for higher-density legacy configurations. Connections toward another network device consume an access port, so endpoint count and interconnection requirements must be considered together. A legacy replacement order must preserve the existing copper connection plan rather than assume a separate higher-speed uplink.

8.8 Gbps switching capacity provides the internal switching fabric, while 2.4 Gbps maximum forwarding bandwidth sets the front-panel traffic ceiling. 1.8 Mpps forwarding describes the packet-handling rate for this model. An 8 MB shared packet buffer handles traffic bursts across the ports, and 8000 MAC entries bound the learned-address table. Cisco WS-C2950-12 uses 16 MB DRAM and 8 MB flash memory for operation and software storage. STP and PVST+ control Layer 2 loops; LACP and PAgP negotiate EtherChannel links. IGMP snooping limits multicast delivery to requesting ports, while VTP and DTP handle VLAN and trunk configuration. Port security, TACACS+, and RADIUS provide access controls and administrative authentication. Local configuration uses the console CLI, with Telnet and SNMP available for in-band management. Inter-VLAN forwarding requires a separate routing device because the switch does not perform IP routing. 30W maximum power draw establishes the chassis allowance for electrical and thermal planning without an endpoint PoE load.
ORM Systems offers WS-C2950-12 new sealed or certified refurbished; specify condition, quantity, power cord, and mounting requirements on the purchase order. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, clean boot, PSU status, and fan status; firmware is verified and configurations are wiped to factory default. ORM warranties are up to 3-year extended for new units and up to 1 year for certified refurbished units, with 30-day returns on every condition, terms apply; Cisco warranty coverage and service have ended. For enterprise and volume orders, PO is accepted, Net-30 applies for government, and RMA includes advance replacement across UK, EU, US, and MEA.

When replacement equipment must be staged with traffic visibility before installation, the Catalyst 2950 supports SPAN plus four built-in RMON groups covering history, statistics, alarms, and events. Keep monitoring requirements separate from endpoint connectivity, and specify the analyzer connection and staging configuration before placing the purchase order.
Sites retaining a shared management workflow can use Cisco CMS to manage a cluster of 16 interconnected switches through one IP address. Command-switch and member-switch roles remain part of the configuration plan. Identify those roles and the existing management configuration before specifying replacement quantities on the purchase order.
When a branch requires wall mounting rather than rack installation, the Catalyst 2950 must be mounted with its front panel facing up to meet safety requirements. Plan the supporting surface and cable arrangement around that orientation. Specify wall-mounting hardware and confirm the installation position before the purchase order.
Gigabit access or optical uplinks
WS-C2950-12 limits copper connections to 10/100 Mbps and has no optical ports or uplink expansion bay. Gigabit or fiber requirements exceed this hardware configuration.
PoE power for connected endpoints
WS-C2950-12 does not deliver PoE through its Ethernet ports. A purchase requirement to power attached devices from the switch cannot be met by this model.
Routing between separate VLANs
WS-C2950-12 forwards Layer 2 traffic but does not provide inter-VLAN IP routing. A requirement for the switch itself to act as a routing gateway exceeds its capabilities.
Active Cisco manufacturer support
WS-C2950-12 belongs to the retired Catalyst 2950 family, and Cisco support has ended. Purchasing new sealed inventory does not restore manufacturer support eligibility.

WS-C2950-12 uses the WS-C2950 family prefix for the Catalyst 2950 switch and 12 for its twelve 10/100 Mbps ports. The complete identifier selects a standalone, managed, fixed-configuration model with Standard Image software. No separate uplink or software-tier suffix appears on this part number.
WS-C2950-12 supports console and Telnet CLI access, web-based Cisco CMS, device manager, Network Assistant, and SNMP management through tools including CiscoWorks. Embedded Cisco Networking Services agents also support automated configuration. These management paths serve local configuration, remote administration, monitoring, and configuration updates rather than requiring a cloud dashboard.
No, WS-C2950-12 belongs to the retired Catalyst 2950 family, and Cisco support has ended. New sealed condition does not restart manufacturer support or the original hardware warranty. An order requiring active Cisco technical support or ongoing manufacturer software maintenance must exclude this retired model.
ORM Systems offers WS-C2950-12 new sealed with up to 3-year extended warranty, or certified refurbished with up to 1 year. Every condition has 30-day returns, terms apply. Cisco's original limited lifetime hardware warranty and service have ended. Certified refurbished units are inspected, bench-tested, firmware verified, and wiped to factory default.
No, WS-C2950-12 supports Standard Image software only, not Enhanced Image. Changing the software file does not add Enhanced Image rate limiting or security filtering to this hardware. Specify the Standard Image feature set when matching a replacement unit to an existing configuration or purchasing lab equipment.
No, WS-C2950-12 does not provide PoE on its Ethernet ports. Attached endpoints need an independent power source because the copper connections carry network traffic without supplying endpoint power. Treat this model as a data-connectivity purchase rather than a powered-access switch when preparing the equipment order.
WS-C2950-12 has no dedicated uplink connections; another network device connects through one of its twelve 10/100 Mbps copper ports. The chassis has no optical uplink interface or removable network-module bay. Reserve an access port for each interconnection when matching the switch to an existing cable plan.
No, WS-C2950-12 is a standalone switch without dedicated hardware-stacking interfaces. Cisco CMS can instead manage a cluster of 16 interconnected switches through one IP address. That arrangement centralizes management through command and member roles; it does not create a dedicated stacking connection or increase the chassis forwarding bandwidth.
WS-C2950-12 provides an 8.8 Gbps switching fabric, 2.4 Gbps maximum forwarding bandwidth, and 1.8 Mpps forwarding. The fabric rating and forwarding bandwidth describe different limits and should not be treated as interchangeable. An 8 MB packet buffer is shared across the ports for handling traffic bursts.
WS-C2950-12 uses an internal AC supply and can receive external DC through PWR300-AC-RPS-N1. AC operation supports 100-127V or 200-240V, while the external DC input is 12V. The chassis draws a maximum of 30W and does not contain a second internal power-supply bay for redundancy.
WS-C2950-24 has twenty-four 10/100 Mbps access ports, whereas WS-C2950-12 has twelve. Both models use Standard Image software and belong to the retired Catalyst 2950 family. The smaller model matches legacy twelve-port configurations; the larger model matches legacy configurations requiring twenty-four copper connections.
WS-C2950SX-24 has two fixed 1000BASE-SX fiber uplinks, whereas WS-C2950-12 has no dedicated uplinks. The fiber model also carries twenty-four copper access ports. Both models are discontinued: the first matches legacy fiber-uplink configurations, while the second matches smaller configurations using copper connections exclusively.
No, the Catalyst 2950 performs Layer 2 switching rather than inter-VLAN IP routing. VLAN and trunk configuration can separate and transport traffic, but a separate routing device must provide communication between IP networks. Standard Image software does not turn this chassis into a Layer 3 routing gateway.
The Catalyst 2950-12 uses a full-width 1U rack-mount chassis measuring 43.6 mm high, 444.5 mm wide, and 241.8 mm deep, with a weight of 3 kg. Table, shelf, and wall installation are also possible. Wall installations must place the front panel facing up for safety compliance.
WS-C2950-12 supports STP, PVST+, LACP, PAgP, IGMP snooping, VTP, and DTP for Layer 2 operation. Port security, TACACS+, and RADIUS add endpoint-access and administrative controls. These features address loops, link aggregation, multicast distribution, VLANs, and authentication without adding IP routing or Enhanced Image functionality.
