USED

16/36 10BaseT/100BaseTX Ports

Delivers up to 200 Mbps of bandwidth (full duplex) Layer 2; forwards and filters backflow at full wire speed on each port

Autosensing on each port

Detects the speed of the attached device and automatically configures the port for 10- or 100-Mbps operation

Integrated Switching

Provides fewer points of management for remote and small branch offices

Support for 802.1P QoS

Supports QoS based on the Institute of Electrical and Electronics Engineers (IEEE) class-of-service (CoS) and port-based prioritization, allowing the switch to change the CoS settings of tagged packets on a per-port basis

802.1Q Trunking

Allows the setup of separate VLANs with tagged and untagged framing; trunking is used to save ports when creating a link between two devices implementing VLANs

802.1D Spanning Tree (a Layer 2 link-management protocol that provides path redundancy while preventing undesirable loops in the network)

Simplifies network configuration and improves fault tolerance

Voice Virtual LAN (VLAN) feature for IP Phones

Enables phones to be placed into their own VLANs without the need for end-user intervention; a user can plug the phone into the switch, and the switch provides the phone with the necessary VLAN information

Port-Based Reclassification for Queues on each 10/100 that are Configurable using a Weighted Round Robin (WRR) Scheduler

Enables users to prioritize mission-critical traffic, such as VoIP and IP-based video applications over regular traffic

Media Access Control (MAC)-Based Port-Level Security

Prevents unauthorized stations from accessing the switch; Cisco fully supports the entire set of Requests for Comments (RFCs)

Multifunction LEDs per Port for Port Status

Provide a comprehensive and convenient visual management system

Cisco IOS Command-Line Interface (CLI)

Provides configuration through Cisco IOS CLI and provides common user interface for all the router functions

Multicast Management Support

Offers Internet Group Management Protocol (IGMP) snooping in hardware for management support

Memory

Features 4-/8-MB shared-memory architecture that is shared across all ports

SNMP Management

Offers support for Simple Network Management Protocol (SNMP) Management Information Base (MIB) manageable via a MIB browser

Cisco Pre-standard Power over Ethernet (optional)

EtherSwitch with the external power chassis or internal power supply upgrades can power Cisco IP Phones and wireless access points
