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 |

Provides fewer points of management for remote and small branch offices |
|
Support for 802.1P QoS |

|
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 |

Simplifies network configuration and improves fault tolerance |
|
Voice Virtual LAN (VLAN) feature for IP Phones |

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

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 |
|

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 |
