    14.88 mpps

    Switching capacity in gigabits per second (Gbps)

    20 Gbps

    Layer 2 Switching

    Spanning Tree Protocol

    Standard 802.1d Spanning Tree support
    Fast convergence using 802.1w (Rapid Spanning Tree [RSTP]), enabled by default
    Multiple Spanning Tree instances using 802.1s (MSTP); 8 instances are supported
    Per-VLAN Spanning Tree Plus (PVST+) and Rapid PVST+ (RPVST+); 126 instances are supported

    Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP)
    Up to 8 groups
    Up to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad link aggregation

    VLAN

    Support for up to 4,094 VLANs simultaneouslyPort-based and 802.1Q tag-based VLANs; MAC-based VLAN; protocol-based VLAN; IP subnet-based VLAN
    Management VLAN

    Guest VLAN, unauthenticated VLAN
    Dynamic VLAN assignment via RADIUS server along with 802.1x client authentication
    CPE VLAN

    Voice VLAN

    Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS. 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. This feature is also known as Multicast VLAN Registration (MVR)

    VLAN Translation

    Support for VLAN One-to-One Mapping. In VLAN One-to-One Mapping, on an edge interface customer VLANs (C-VLANs) are mapped to service provider VLANs (S-VLANs) and the original C-VLAN tags are replaced by the specified S-VLAN

    Q-in-Q

    VLANs transparently cross a service provider network while isolating traffic among customers

    Selective Q-in-Q

    Selective Q-in-Q is an enhancement to the basic Q-in-Q feature and provides, per edge interface, multiple mappings of different C-VLANs to separate S-VLANs
    Selective Q-in-Q also allows configuring of Ethertype (Tag Protocol Identifier [TPID]) of the S-VLAN tag
    Layer 2 protocol tunneling over Q-in-Q is also supported

    Generic VLAN Registration Protocol (GVRP)/Generic Attribute Registration Protocol (GARP)

    Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP) enable automatic propagation and configuration of 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 black holing 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 2K multicast groups (source-specific multicasting is also supported)

    IGMP Querier

    IGMP querier is used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast router

    Head-of-Line (HOL) blocking

    HOL blocking prevention

    Loopback Detection

    Loopback detection provides protection against loops by transmitting loop protocol packets out of ports on which loop protection has been enabled. It operates independently of STP

    Layer 3

    IPv4 routing

    Wirespeed routing of IPv4 packets
    Up to 990 static routes and up to 128 IP interfaces

    IPv6 routing

    Wirespeed routing of IPv6 packets

    Layer 3 Interface

    Configuration of Layer 3 interface on physical port, Link Aggregation (LAG), VLAN interface, or loopback interface

    Classless Interdomain Routing (CIDR)

    Support for classless interdomain routing

    Policy-Based Routing (PBR)

    Flexible routing control to direct packets to different next hop based on IPv4 or IPv6 Access Control List (ACL)

    DHCP Server

    Switch functions as an IPv4 DHCP server serving IP addresses for multiple DHCP pools/scopes

    Support for DHCP options

    DHCP relay at Layer 3

    Relay of DHCP traffic across IP domains

    User Datagram Protocol (UDP) relay

    Relay of broadcast information across Layer 3 domains for application discovery or relaying of Bootstrap Protocol (BOOTP)/DHCP packets

    Stacking

     

    Hardware stack

    Up to 4 units in a stack. Up to 192 ports managed as a single system with hardware failover

    High availability

    Fast stack failover delivers minimal traffic loss. Support link aggregation across multiple units in a stack

    Plug-and-play stacking configuration/management

    Master/backup for resilient stack control
    Autonumbering
    Hot swap of units in stack
    Ring and chain stacking options, auto stacking port speed, flexible stacking port options

    High-speed stack interconnects

    Cost-effective high-speed 10G fiber interfaces.

    Security

    Secure Shell (SSH) Protocol

    SSH is a secure replacement for Telnet traffic. Secure Copy Protocol (SCP) also uses SSH. SSH v1 and v2 are supported

    Secure Sockets Layer (SSL)

    SSL support: Encrypts all HTTPS traffic, allowing highly secure access to the browser-based management GUI in the switch

    IEEE 802.1X (Authenticator role)

    802.1X: Remote Authentication Dial-In User Service (RADIUS) authentication and accounting, MD5 hash; guest VLAN; unauthenticated VLAN, single/multiple host mode and single/multiple sessions
    Supports time-based 802.1X; 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. This avoids accidental topology loops

    STP Root Guard

    This prevents edge devices not in the network administrator’s control from becoming Spanning Tree Protocol root nodes

    STP loopback guard

    Provides additional protection against Layer 2 forwarding loops (STP loops)

    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.

    Run-time defenses (Executable Space Protection [X-Space], Address Space Layout Randomization [ASLR], Built-In Object Size Checking [BOSC])

    Private VLAN

    Private VLAN provides security and isolation between switch ports, which helps ensure that users cannot snoop on other users’ traffic; supports multiple uplinks

    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
