Security
provide IP Layer 3 filtering based on source/destination IP address/subnet and source/destination TCP/UDP port number
Monitor and diagnostics
• Multiple user authentication methods
− IEEE 802.1X
uses an IEEE 802.1X supplicant on the client in conjunction with a RADIUS server to authenticate in accordance
with industry standards
− Web-based authentication
provides a browser-based environment, similar to IEEE 802.1X, to authenticate clients that do not support the
IEEE 802.1X supplicant
− MAC-based authentication
authenticates the client with the RADIUS server based on the client's MAC address
• Authentication flexibility
− Multiple IEEE 802.1X users per port
provides authentication of multiple IEEE 802.1X users per port; prevents a user from "piggybacking" on another
user's IEEE 802.1X authentication
− Concurrent IEEE 802.1X, Web, and MAC authentication schemes per port
switch port will accept up to 32 sessions of IEEE 802.1X, Web, and MAC authentications

• Secure Sockets Layer (SSL)
encrypts all HTTP traffic, allowing secure access to the browser-based management GUI in the switch
• 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
• Secure FTP
allows secure file transfer to and from the switch; protects against unwanted file downloads or unauthorized copying of a
switch configuration file
• Switch management logon security
helps secure switch CLI logon by optionally requiring either RADIUS or TACACS+ authentication
• STP BPDU port protection
blocks Bridge Protocol Data Units (BPDUs) on ports that do not require BPDUs, preventing forged BPDU attacks
• DHCP protection
blocks DHCP packets from unauthorized DHCP servers, preventing denial-of-service attacks
• Dynamic ARP protection
blocks ARP broadcasts from unauthorized hosts, preventing eavesdropping or theft of network data
• Dynamic IP lockdown
works with DHCP protection to block traffic from unauthorized hosts, preventing IP source address spoofing
• STP Root Guard
protects the root bridge from malicious attacks or configuration mistakes
• Identity-driven ACL
enables implementation of a highly granular and flexible access security policy and VLAN assignment specific to each
authenticated network user
• Per-port broadcast throttling
configures broadcast control selectively on heavy traffic port uplinks
