•          IEEE 802.1AB Link Layer Discovery Protocol (LLDP) — automated device discovery protocol provides easy mapping using network management applications
•          sFlow (RFC 3176) — wire-speed traffic accounting and monitoring
•          Advanced IRF technology stacking — locally connects up to four 4210G switches using 10 Gigabit Ethernet or CX4 local connections; improves resiliency by spreading aggregated links across multiple stacked units; provides simplified management with single IP management and a unified control interface per stack

Layer 2 switching

•          VLAN support and tagging — support IEEE 802.1Q with 4,094 simultaneous VLAN IDs
•          GARP VLAN Registration Protocol — allows automatic learning and dynamic assignment of VLANs
•          IP multicast snooping and data-driven IGMP — automatically prevents flooding of IP multicast traffic
•          Jumbo packet support — supports up to 9220-byte frame size to improve the performance of large data transfers
•          IEEE 802.1ad QinQ — increases the scalability of an Ethernet network by providing a hierarchical structure; connects multiple LANs on a high-speed campus or metro network

Layer 3 routing

•          Static IP routing — provides manually configured Layer 3 routing

Security

•          Access control lists (ACLs) — provide IP Layer 3 filtering based on source/destination IP address/subnet and source/destination TCP/UDP port number

•          Secure Shell — encrypts all transmitted data for secure remote CLI access over IP networks
•          Secure Web management with HTTPS and SSL — encrypts all HTTP traffic, allowing secure access to the browser-based management GUI in the switch
•          IEEE 802.1X and RADIUS network logins — control port-based access for authentication and accountability
•          Secure FTP — allows secure file transfer to and from the switch; protects against unwanted file downloads or unauthorized copying of a switch configuration file
•          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
•          Switch management logon security — can require either RADIUS or TACACS+ authentication for secure switch CLI logon
