QuickSpecs
Overview
Broadcast control: allows limitation of broadcast traffic rate to cut down on unwanted broadcast traffic on the network
Security
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
Secure Sockets Layer (SSL): encrypts all HTTP traffic, allowing secure access to the browser-based management GUI in
the switch
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: utilizes an industry-standard user authentication with an IEEE 802.1X supplicant on the client in conjunction
with a RADIUS server
Web-based: similar to IEEE 802.1X, it provides a browser-based environment to authenticate clients
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
Physical security:
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
Convergence
LLDP-MED (Media Endpoint Discovery): is 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 a VLAN for IP phones
Flexibility
Quiet operation:
Fanless design (2520-8-PoE and 2520G-8-PoE switches): enables quiet operation for deployment in open spaces
Variable-speed fans (2520-24-PoE switch): improves fan speed for the operating environment while lowering noise and
energy consumption levels
