    Specification
    Layer   Layer 2, 3 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); 16 instances 
    Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP)
    Port grouping/link aggregation   Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP)
    Up to 32 groups
    Up to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad LAG
    Voice VLAN   Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of 
    QoS. Auto voice capabilities deliver networkwide zero-touch deployment of voice endpoints and call 
    control devices.
    VLAN    Support for up to 4094 active VLANs simultaneously; port-based and 802.1Q tag-based VLANs;
    MAC-based VLAN Management VLAN Private VLAN with promiscuous, isolated, and community port
    Guest VLAN, unauthenticated VLAN, protocol-based VLAN, IP subnet-based VLAN, CPE VLAN
    Dynamic VLAN assignment using RADIUS server along with 802.1x client authentication
    Multicast TV VLAN  Multicast TV VLAN allows the single multicast VLAN to be shared in the network while subscribers 
    main in separate VLANs. This feature is also known as Multicast VLAN Registration (MVR).
    Q-in-Q VLANs transparently cross over a service provider network while isolating traffic among customers.
    GVRP/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 port
    faults to prevent forwarding loops and blackholing of traffic in switched networks.
    DHCP relay at Layer 2 Relay of DHCP traffic to DHCP server in a different VLAN. Works with DHCP option 82.
    IGMP (versions 1, 2, and 3) snooping  Internet Group Management Protocol (IGMP) limits bandwidth-intensive multicast traffic to only the
    equesters; supports 4K 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.
    HOL blocking Head-of-line (HOL) blocking.
    IPv4 routing Wirespeed routing of IPv4 packets, Up to 7K routes and up to 256 IP interfaces
    Wirespeed IPv6 static routing Up to 7K routes and up to 256 IPv6 interfaces
    Layer 3 interface Configuration of Layer 3 interface on physical port, LAG, VLAN interface, or loopback interface
    CIDR Support for classless interdomain routing
    RIP v2 Support for Routing Information Protocol version 2 for dynamic routing
    VRRP   Virtual Router Redundancy Protocol (VRRP) delivers improved availability in a Layer 3 network by 
    providing redundancy of the default gateway servicing hosts on the network. VRRP versions 2 and 3 are 
    supported. Up to 255 virtual routers are supported
    Policy-based routing (PBR) Flexible routing control to direct packets to different next hop based on IPv4 or IPv6 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 
    BOOTP/DHCP packets
    Console port  Cisco Standard RJ45 console port
    OOB management port Dedicated Gigabit management port for out-of-band management on SG550XG models
    RPS RPS connector
    USB slot USB Type-A slot on the front panel of the switch for easy file and image management
    Buttons Reset button
    Cabling type Unshielded twisted pair (UTP) Category 5 or better; fiber options (SMF and MMF); coaxial SFP+
    LEDs System, master, fan, RPS, stack ID, link/speed per port
    Power 100 - 240V 47 - 63 Hz, internal, universal
    Certification UL (UL 60950), CSA (CSA 22.2), CE mark, FCC Part 15 (CFR 47) Class A
    Operating temperature 32° to 122°F (0° to 50°C)
    Storage temperature 4° to 158°F (-20° to 70°C)
    Operating humidity 10% to 90%, relative, noncondensing
    Storage humidity 10% to 90%, relative, noncondensing
