Security

Port security: allows access only to specified MAC addresses, which can be learned or specified by the administrator
Protected ports: provides increased security by allowing specified ports to be isolated from all other ports on the switch; the protected port or ports can only communicate with the uplink or shared resources New!
MAC address lockout: prevents configured particular MAC addresses from connecting to the network
Multiple user authentication methods:
- IEEE 802.1X: industry-standard method of user authentication using an IEEE 802.1X supplicant on the client in conjunction with a RADIUS server
- Web-based authentication: similar to IEEE 802.1X, provides a browser-based environment to authenticate clients that do not support the IEEE 802.1X supplicant
- MAC-based authentication: client is authenticated with the RADIUS server based on the client's MAC address
Switch management logon security: can require either RADIUS or TACACS+ authentication for secure switch CLI logon
Multiple IEEE 802.1X users per port: provides authentication of up to two IEEE 802.1X users per port; prevents user "piggybacking" on another user's IEEE 802.1X authentication
STP BPDU port protection: blocks Bridge Protocol Data Units (BPDUs) on ports that do not require BPDUs, preventing forged BPDU attacks
Secure FTP: allows secure file transfer to/from the switch; protects against unwanted file downloads or unauthorized copying of switch configuration file
RADIUS/TACACS+: eases switch management security administration by using a password authentication server
Source-port filtering: allows only specified ports to communicate with each other
Secure Shell (SSHv2): encrypts all transmitted data for secure, remote command-line interface (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
