It is part of the Cisco Catalyst 3750-E series, which is known for its high performance and reliability. The switch supports 10/100/1000Base-T Ethernet connectivity and can be used to connect a variety of networking devices, including computers, servers, and other switches. It also has a number of advanced features, such as support for Quality of Service (QoS), which allows you to prioritize certain types of network traffic for better performance, and EnergyWise technology, which helps you to monitor and manage power usage on your network. The WS-C3750E-48PD-SF has a durable design and is built to withstand the rigors of a busy network environment. VLAN and Spanning Tree Protocol Configuration and Support The WS-C3750E-48PD-SF Catalyst 3750-E 48-Ports Multi-Layer Ethernet Switch supports VLAN and Spanning Tree Protocol (STP) configuration and has the following features: VLAN support: The switch supports up to 4,096 VLANs and can be configured for VLAN trunking protocol (VTP), which allows for VLAN information to be propagated across the network. VLANs can be configured using the command-line interface (CLI) or through the web-based graphical user interface (GUI). Spanning Tree Protocol (STP) support: The switch supports STP, Rapid STP (RSTP), and Multiple STP (MSTP). STP can be used to prevent network loops and ensure network redundancy. The switch can be configured to support various STP modes, including STP, RSTP, and MSTP. The switch also supports portfast and BPDU guard features. VLAN Trunking Protocol (VTP): VTP allows VLAN information to be shared among switches in a network. The switch can be configured as a VTP server, client, or transparent mode. Private VLANs: The switch supports private VLANs, which provide isolation between devices in the same VLAN. Voice VLANs: The switch supports voice VLANs, which separate voice and data traffic to provide better quality of service (QoS) for voice traffic. Layer 3 VLAN routing: The switch can perform Layer 3 routing between VLANs, and supports various routing protocols such as OSPF, EIGRP, and BGP. CLI and web-based GUI: The switch can be configured using the CLI or the web-based GUI. Port security: The switch supports port security, which allows network administrators to restrict access to a port based on the MAC address of the device connecting to the port. Quality of Service (QoS): The switch supports QoS features such as traffic shaping, queuing, and prioritization to provide better performance for critical network traffic. Link aggregation: The switch supports link aggregation (EtherChannel) to provide increased bandwidth and redundancy between switches. Network Management Features and Capabilities The Cisco WS-C3750E-48PD-SF Catalyst 3750-E 48-Ports Multi-Layer Ethernet Switch offers a variety of network management features and capabilities, including: Simple Network Management Protocol (SNMP): Allows for centralized network management and monitoring. Remote Monitoring (RMON): Allows for remote monitoring of traffic, network usage, and errors. Cisco Network Assistant: Provides a graphical user interface for configuring, monitoring, and troubleshooting Cisco network devices. Command-line Interface (CLI): Allows for configuring and monitoring the switch through a command-line interface. Cisco IOS Software: Provides a modular architecture for adding new features and functions. VLAN Support: Allows for the creation of multiple virtual networks on a single physical switch. Quality of Service (QoS): Allows for the prioritization of network traffic to ensure that critical applications receive the necessary bandwidth and resources. Port Mirroring: Allows for the replication of traffic from one or more ports to a designated monitoring port. Spanning Tree Protocol (STP): Prevents network loops by blocking redundant links in a network. Link Aggregation Control Protocol (LACP): Provides automatic configuration of link aggregation groups (LAGs) between the switch and other network devices. Multicast Support: Allows for the efficient delivery of data to multiple recipients on a network. Access Control Lists (ACLs): Provide the ability to control network access based on IP addresses, MAC addresses, and other criteria. DHCP Snooping: Prevents rogue DHCP servers from distributing IP addresses on the network. Port Security: Prevents unauthorized access to a network by limiting the number of MAC addresses that can be learned on a port. Simple Network Time Protocol (SNTP): Provides time synchronization between network devices to ensure consistent timing across the network.
