Overview:

WS-C3560X-24T-L

The Cisco Catalyst 3750-X  and 3560-X ( WS-C3560X-24T-S ) Series Switches are an enterprise-class lines of stackable and standalone switches, respectively. And these switches provide high availability, scalability, security, energy efficiency. Moreover, its ease of operation with innovative features such as Cisco StackPower (available only on the Catalyst 3750‑X), IEEE 802.3 at Power over Ethernet Plus (PoE+) configurations, optional network modules, redundant power supplies, and Media Access Control Security (MACsec) features.
In other words,  the Cisco Catalyst 3750-X Series with StackWise^® Plus technology provides scalability, ease of management and investment protection for the evolving business needs. The Cisco Catalyst 3750-X and 3560-X enhance productivity by enabling applications such as IP telephony, wireless, and video for borderless network experience.

Above all, Cisco Catalyst 3750-X and 3560-X Series primary features:

• 24 and 48 10/100/1000 PoE+, non-PoE models, and 12 and 24 GE SFP port models.
• 24 and 48 10/100/1000 UPOE-capable models with Energy Efficient Ethernet (EEE) support.
• Four optional uplink network modules with GE or 10GE ports.
• Industry first PoE+ with 30W power on all ports in 1 rack unit (RU) form factor.
• Dual redundant, modular power supplies and fans.
• Media Access Control Security (MACsec) hardware-based encryption.
• Flexible NetFlow and switch-to-switch hardware encryption with the Service Module uplink.
• Open Shortest Path First (OSPF) for routed access in IP Base image.
• IPv4 and IPv6 routing, Multicast routing, advanced quality of service (QoS), and security features in hardware.
• Enhanced limited lifetime warranty (LLW) with next business day (NBD) advance hardware replacement.
• 90 day access to Cisco Technical Assistance Center (TAC) support.
• Enhanced Cisco EnergyWise for operational cost optimization by measuring actual power consumption of the PoE devices
• And reporting, and reducing energy consumption across the network

Software:

In addition to IP Base and IP Services feature sets, the Cisco Catalyst 3750-X and 3560-X Series come with a new LAN Base feature set.

• LAN Base: Enhanced Intelligent Services
• IP Base: Baseline Enterprise Services
• IP Services: Enterprise Services

Moreover, The LAN Base feature set offers enhanced intelligent services that includes comprehensive Layer 2 features. The IP Base feature set provides baseline enterprise services in addition to all LAN Base features. IP Base also includes the support for routed access, StackPower, and MACsec.

The IP Services feature set provides full enterprise services that includes advanced Layer 3 features such as Enhanced Interior Gateway Routing Protocol (EIGRP), Open Shortest Path First (OSPF), Border Gateway Protocol (BGP), Protocol Independent Multicast (PIM), and IPv6 routing such as OSPFv3 and EIGRPv6.

IP Services feature set also includes the Embedded Event Manager (EEM) and IP service-level agreements (SLAs) initiator functionalities.

In conclusion, The Cisco Catalyst 3750-X Series Switches with LAN Base feature set can only stack with other Cisco Catalyst 3750-X Series LAN Base switches. A mixed stack of LAN Base switch with IP Base or IP Services features set is not supported.
