Cisco Catalyst 3750 48 10/100/1000T PoE + 4 SFP Enhanced Image

The Cisco Catalyst 3750 Series switches are an innovative product line that improves LAN operating efficiency by combining industry-leading ease of use and the highest resiliency available for stackable switches. This new product series represents the next generation in desktop switches, and features Cisco StackWise technology, a 32-Gbps stack interconnect that allows customers to build a unified, highly resilient switching system-one switch at a time. For mid-sized organizations and enterprise branch offices, the Cisco Catalyst 3750 Series eases deployment of converged applications and adapts to changing business needs by providing configuration flexibility, support for converged network patterns, and automation of intelligent network-services configurations. In addition, the Cisco Catalyst 3750 Series is optimized for high-density Gigabit Ethernet deployments and includes a diverse range of switches that meet access, aggregation, or small-network backbone-connectivity requirements.

The Cisco Catalyst 3750G-48PS has Enhanced Multilayer Software Image (EMI) installed. The EMI provides a richer set of enterprise-class features including advanced hardware-based IP unicast and multicast routing.

Warranty: Limited lifetime warranty.

System
Management Capabilities	Cisco IOS CLI support provides common user interface and command set with all Cisco routers and Cisco Catalyst desktop switches. Service Assurance Agent support facilitates service-level management throughout the LAN. Switching Database Manager templates for access, routing, and VLAN deployment scenarios allow the administrator to easily maximize memory allocation to the desired features based on deployment-specific requirements. VLAN trunks can be created from any port, using either standards-based 802.1Q tagging or the Cisco Inter-Switch Link (ISL) VLAN architecture. Up to 1024 VLANs per switch or stack and up to 128 spanning-tree instances per switch are supported. 4000 VLAN IDs are supported. Voice VLAN simplifies telephony installations by keeping voice traffic on a separate VLAN for easier administration and troubleshooting. Cisco VLAN Trunking Protocol (VTP) supports dynamic VLANs and dynamic trunk configuration across all switches. Cisco Group Management Protocol (CGMP) server functions enable a switch to serve as the CGMP router for CGMP client switches. EMI is required. IGMP snooping provides fast client joins and leaves of multicast streams and limits bandwidth-intensive video traffic to only the requestors. Remote Switch Port Analyzer (RSPAN) allows administrators to remotely monitor ports in a Layer 2 switch network from any other switch in the same network. For enhanced traffic management, monitoring, and analysis, the Embedded Remote Monitoring (RMON) software agent supports 4 RMON groups (history, statistics, alarms, and events).
