Logging: local and remote logging of events via SNMP (v2c and v3) and syslog. IPv6 host: allows switches to be managed using IPv6 protocols. 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: power LED 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 FAQ for more details). RJ-45 serial console port: easily accessible on front of unit to access switch CLI. Switch on a chip: highly integrated, high-performance switch design with a non-blocking architecture. 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: industry-standard user authentication using 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. Kensington Lock: 2520-8-PoE and 2520G-8-PoE switches include a Kensington Lock slot for securing the switches in open-space deployments.
