Voice VRJ45: Voice traffic is automatically assigned to a voice-specific VRJ45 and treated with appropriate levels of QoS

Internet Group Management Protocol Versions 1 and 2 Snooping: Internet Group Management Protocol limits bandwidth-intensive multicast traffic to only the requesters; supports 256 multicast groups

Head-of-Line (HOL) Blocking: Head-of-line blocking

IPv6 QoS: Prioritize IPv6 packets in hardware

Multicast Listener Discovery Snooping: Deliver IPv6 multicast packets only to the required receivers

IPv6 Applications: Web, ping, Simple Network Time Protocol, Trivial File Transfer Protocol, RADIUS, syslog, DNS client

IPv6 RFCs Supported: RFC 2463: ICMP version 6
RFC 3513: IPv6 address architecture
RFC 4291: IPv6 addressing architecture
RFC 2460: IPv6 specification
RFC 2461: Neighbor discovery for IPv6
RFC 2462: IPv6 stateless address auto-configuration
RFC 1981: Path maximum transmission unit discovery
RFC 4007: IPv6 scoped address architecture
RFC 3484: Default address selection mechanism
RFC 4214: ISATAP tunneling
RFC 4293: MIB IPv6: Textual conventions and general group
RFC 3595: Textual conventions for IPv6 flow label

Remote Monitoring: Embedded RMON software agent supports one RMON group (statistics) for enhanced traffic management, monitoring and analysis

IPv4 and IPv6 Dual Stack: Coexistence of both protocol stacks to ease migration

Firmware Upgrade: Web browser upgrade (HTTP) and TFTP

Port Mirroring: Traffic on a port can be mirrored to another port for analysis with a network analyzer or RMON probe Up to 4 source ports can be mirrored to one destination port. A single session is supported

VRJ45 Mirroring: Traffic from a VRJ45 can be mirrored to a port for analysis with a network analyzer or RMON probe Up to 4 source VRJ45s can be mirrored to one destination port. A single session is supported

Dynamic Host Configuration Protocol (Options 66 and 67): Dynamic Host Configuration Protocol options facilitate tighter control from a central point (DHCP server) to obtain IP address, auto-configuration (with configuration file download)

Text-Editable Config Files: Config files can be edited with a text editor and downloaded to another switch, facilitating easier mass deployment

Smartports: Simplified configuration of QoS and security capabilities

Cloud Services: Support for FindIT Network Discovery Utility

Localization: Localization of GUI and documentation into multiple languages

Other Management: HTTP, RADIUS, port mirroring, TFTP upgrade, DHCP client, BOOTP, SNTP, ping, syslog

IEEE 802.1X (Authenticator Role): RADIUS authentication and accounting, MD5 hash

Port Security: Locks MAC addresses to ports and limits the number of learned MAC addresses

Storm Control: Broadcast, multicast and unknown unicast

 Power Dedicated to PoE: 32W

Number of Ports That Support PoE: 4

 Link Layer Discovery Protocol (802.1ab) with LLDP-MED Extensions: Link Layer Discovery Protocol allows the switch to advertise its identification, configuration and capabilities to neighboring devices, which store the data in an MIB. LLDP-MED is an enhancement to LLDP that adds the extensions needed for IP phones
Cisco Discovery Protocol: The switch advertises itself using the Cisco Discovery Protocol

 Priority Levels: 4 hardware queues
Scheduling: Strict priority and weighted round-robin
Queue assignment based on differentiated services code point (DSCP) and class of service (802.1p/CoS)
Class of Service: Port based, 802.1p VRJ45 priority based, IPv4/v6 IP precedence/type of service (ToS)/DSCP based, Differentiated Services (DiffServ)
Rate Limiting: Ingress policer, per VRJ45 and per port
