RMON: provides advanced monitoring and reporting capabilities for statistics, history, alarms, and events. Find-Fix-Inform: finds and fixes common network problems automatically, then informs administrator. Locator LED: allows users to set the locator LED on a specific switch to either turn on, blink, or turn off; simplifies troubleshooting by making it easy to locate a particular switch within a rack of similar switches.Per-port LEDs: provides an at-a-glance view of status, activity, speed, and full-duplex operation. Power and fault LEDs: display any issues. Auto-MDIX: automatically adjusts for straight-through or crossover cables on all ports. Small Form-Factor Pluggable (SFP) slots: dual-personality ports allow for either copper or fiber connectivity such as Gigabit-SX, -LX, -LH, and -BX or 100-FX and -BX. IEEE 802.3af Power over Ethernet: provides up to 15.4 W per port to IEEE 802.3af-compliant PoE-powered devices such as IP phones, wireless access points, and security cameras (see product specifications for total PoE power available); supports some prestandard PoE devices (see product FAQs for more details).
RJ-45 serial console port: front of unit location provides easy access to switch CLI. Switch on a chip: provides highly integrated, high-performance switch design with a non-blocking architecture. Jumbo packet support: supports up to 9216-byte frame size to improve performance of large data transfers. Port trunking and link aggregation. Trunking: supports up to eight links per trunk to increase bandwidth and create redundant connections.
IEEE 802.3ad Link Aggregation Protocol (LACP): eases configuration of trunks through automatic configuration. IEEE 802.1s Multiple Spanning Tree Protocol (MSTP): provides high link availability in multiple VLAN environments by allowing multiple spanning trees; provides legacy support for IEEE 802.1w (Rapid Reconfiguration of Spanning Tree Protocol) and IEEE 802.1d (Spanning Tree Protocol).
VLAN support and tagging: supports the IEEE 802.1Q (4,094 VLAN IDs) and up to 256 port-based VLANs simultaneously. GARP VLAN Registration Protocol (GVRP): allows automatic learning and dynamic assignment of VLANs.
Broadcast control: allows limitation of broadcast traffic rate to cut down on unwanted broadcast traffic on the network. Manager and operator privilege levels: enables read-only (operator) and read-write (manager) access on management interfaces. RADIUS/TACACS+ for management access authentication: eases switch management security administration by using a password authentication server.Secure protocols for encryption of management traffic. Secure Shell (SSHv2): encrypts all transmitted data for secure, remote CLI access over IP networks. Simple Network Management Protocol (SNMP) v3: allows encryption of traffic between switch MIBs and network management software. Secure FTP (SFTP): encrypts uploads and downloads of configuration file. Protected ports: prevents designated ports from communicating with each other while allowing access to unprotected ports. Port security: allows access only to specified MAC addresses, which can be learned or specified by the administrator.
MAC address lockout: prevents particular configured MAC addresses from connecting to the network. MAC address lockdown: allows only specified MAC addresses access to the network on a specified port.Denial-of-service (DoS) attack filtering: automatically filters and drops common DoS attack traffic types. User authentication for port access. IEEE 802.1X: utilises an industry-standard user authentication with an IEEE 802.1X supplicant on the client in conjunction with a RADIUS server. MAC-based: client is authenticated with the RADIUS server based on MAC address. Concurrent authentication schemes: each switch port will accept up to two sessions of IEEE 802.1X, Web, and/or MAC authentications concurrently.
Custom banner: displays security policy when users log in to the switch. Spanning Tree Protocol Bridge Protocol Data Unit (BPDU) port protection: blocks BPDUs on ports that do not require BPDUs, preventing forged BPDU attacks. Spanning Tree Protocol Root Guard: when running the spanning tree protocol, protects root bridge from malicious attack or configuration mistakes. Front-panel buttons: provides the ability to disable reset and clear buttons on front panel for added security. LLDP-MED (Media Endpoint Discovery): a standard extension of LLDP that automatically configures network devices such as IP phones.IP multicast snooping and data-driven IGMP: automatically prevents flooding of IP multicast traffic. Voice VLAN: uses LLDP-MED to automatically configure VLAN for IP phones. Selectable queue configuration: increases performance and/or traffic reliability by selecting the number of queues that best meet the requirements of your network applications; switch will map 8 priorities to either 2 or 4 queues. Port-based: prioritise traffic by specifying a port and priority level.
VLAN based: prioritise traffic by specifying a VLAN and priority level. IEEE 802.1p traffic prioritisation: honors and sets IEEE 802.1p priority in the VLAN tag. IP Precedence: honors IP Precedence bits and allows mapping to a priority queue.Differentiated Services Code Point values: honors Differentiated Services Code Point (DSCP) bits and allows mapping to a priority queue. Flow control: helps ensure reliable communications during full-duplex operation. Variable-speed fans: improves fan speed for the operating environment while keeping noise and energy consumption levels to a minimum. Rackable: is mountable in a standard 19-inch rack with included hardware. Wall mountable: allows the switch to be mounted to a wall using included hardware. Surface mountable: allows the product to be mounted above or below a surface (such as a desk or table) with included hardware. Compact size: products are designed to reduce space requirements (see product specifications for exact dimensions). Fans: variable-speed fans help reduce power consumption. Port LEDs: port link and activity LEDs can be turned off to conserve energy.
Port low-power mode: when no link is detected on a port, the port will automatically go into low-power mode to conserve energy.
