    Auto voice capabilities deliver network-wide zero-touch deployment of voice endpoints and call control devices

    Multicast TV VLAN
    Multicast TV VLAN allows the single multicast VLAN to be shared in the network while subscribers remain in separate VLANs (also known as MVR)

    Q-in-Q VLAN
    VLANs transparently cross a service provider network while isolating traffic among customers

    Generic VLAN Registration Protocol (GVRP)/Generic Attribute Registration Protocol (GARP)
    Protocols for automatically propagating and configuring VLANs in a bridged domain

    Unidirectional Link Detection (UDLD)
    UDLD monitors physical connection to detect unidirectional links caused by incorrect wiring or cable/port faults to prevent forwarding loops and blackholing of traffic in switched networks

    Dynamic Host Configuration Protocol (DHCP) Relay at Layer 2
    Relay of DHCP traffic to DHCP server in different VLAN; works with DHCP Option 82

    Internet Group Management Protocol (IGMP) versions 1, 2, and 3 snooping
    IGMP limits bandwidth-intensive multicast traffic to only the requesters; supports 1K multicast groups (source-specific multicasting is also supported)

    IGMP Querier

    Dynamic VLAN assignment

    Web-based authentication
    Web based authentication provides network admission control through web browser to any host devices and operating systems

    STP Bridge Protocol Data Unit (BPDU) Guard
    A security mechanism to protect the network from invalid configurations. A port enabled for BPDU Guard is shut down if a BPDU message is received on that port

    STP Root Guard
    This prevents edge devices not in the network administrator's control from becoming Spanning Tree Protocol root nodes

    DHCP snooping
    Filters out DHCP messages with unregistered IP addresses and/or from unexpected or untrusted interfaces. This prevents rogue devices from behaving as DHCP Servers

    IP Source Guard (IPSG)
    When IP Source Guard is enabled at a port, the switch filters out IP packets received from the port if the source IP addresses of the packets have not been statically configured or dynamically learned from DHCP snooping. This prevents IP Address Spoofing

    Dynamic ARP Inspection (DAI)
    The switch discards ARP packets from a port if there are no static or dynamic IP/MAC bindings or if there is a discrepancy between the source or destination addresses in the ARP packet. This prevents man-in-the-middle attacks

    IP/MAC/Port Binding (IPMB)
    The preceding features (DHCP Snooping, IP Source Guard, and Dynamic ARP Inspection) work together to prevent DOS attacks in the network, thereby increasing network availability

    Secure Core Technology (SCT)
    Makes sure that the switch will receive and process management and protocol traffic no matter how much traffic is received

    Secure Sensitive Data (SSD)
    A mechanism to manage sensitive data (such as passwords, keys, and so on) securely on the switch, populating this data to other devices, and secure autoconfig. Access to view the sensitive data as plaintext or encrypted is provided according to the user-configured access level and the access method of the user

    Layer 2 isolation Private VLAN Edge (PVE) with community VLAN
    PVE (also known as protected ports) provides Layer 2 isolation between devices in the same VLAN, supports multiple uplinks

    Port security
    The ability to lock source MAC addresses to ports and limits the number of learned MAC addresses

    RADIUS/TACACS+
    Supports RADIUS and TACACS authentication. Switch functions as a client

    Storm control
    Broadcast, multicast, and unknown unicast

    RADIUS accounting
    The RADIUS accounting functions allow data to be sent at the start and end of services, indicating the amount of resources (such as time, packets, bytes, and so on) used during the session

    DoS prevention
    Denial-of-service (DOS) attack prevention

    ACLs
    Support for up to 512 rules
    Drop or rate limit based on source and destination MAC, VLAN ID or IP address, protocol, port, differentiated services code point (DSCP)/IP precedence, TCP/UDP source and destination ports, 802.1p priority, Ethernet type, Internet Control Message Protocol (ICMP) packets, IGMP packets, TCP flag, time-based ACLs supported.
    Quality of Service (QoS)Priority levels
    8 hardware queues

    Scheduling
    Strict priority and weighted round-robin (WRR)
    Queue assignment based on DSCP and class of service (802.1p/CoS)

    Class of service
    Port based; 802.1p VLAN priority based; IPv4/v6 IP precedence/type of service (ToS)/DSCP based; differentiated services (DiffServ); classification and remarking ACLs, trusted QoS
