    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.

    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).

    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 requesters; 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.

    Layer 3

    IPv4 routing

    Wirespeed routing of IPv4 packets

    Up to 7K routes and up to 256 IP interfaces

    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

    Hardware stack

    Up to 8 units in a stack. Up to 400 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, autostacking port speed, flexible stacking port options

    High-speed stack interconnects

    Cost-effective high-speed 10G fiber and copper interfaces. Support LAG as stacking interconnects for even higher bandwidth.

    Security

    SSH

    SSH is a secure replacement for Telnet traffic. SCP also uses SSH. SSH versions 1 and 2 are supported.

    SSL

    Secure Sockets Layer (SSL) encrypts all HTTPS traffic, allowing secure access to the browser-based management GUI in the switch.

    IEEE 802.1X (authenticator role)

    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 BPDU Guard

    A security mechanism to protect the networks from invalid configurations. A port enabled for Bridge Protocol Data Unit (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.

    DHCP snooping

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

    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 address 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.

    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.

    Port security

    Ability to lock source MAC addresses to ports and limit the number of learned MAC addresses.

    RADIUS/TACACS+

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

    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.

    Storm control

    Broadcast, multicast, and unknown unicast.

    DoS prevention

    Denial-of-service (DoS) attack prevention.

    Multiple user privilege levels in CLI

    Level 1, 7, and 15 privilege levels.

    ACLs

    Support for up to 2K entries on SG550XG models.

    Support for up to 3K entries on all other models.

    Drop or rate limit based on source and destination MAC, VLAN ID or IP address, protocol, port, DSCP/IP precedence, TCP/User Datagram Protocol (UDP) source and destination ports, 802.1p priority, Ethernet type, Internet Control Message Protocol (ICMP) packets, Internet Group Management Protocol (IGMP) packets, TCP flag; ACL can be applied on both ingress and egress sides.

    Time-based ACLs supported.

    Quality of Service

    Priority levels

    8 hardware queues

    Scheduling

    Strict priority and weighted round-robin (WRR)

    Class of service

    Port based; 802.1p VLAN priority based; IPv4/v6 IP precedence/ToS/DSCP based; DiffServ; classification and remarking ACLs, trusted QoS

    Queue assignment based on differentiated services code point (DSCP) and class of service (802.1p/CoS)

    Rate limiting

    Ingress policer; egress shaping and ingress rate control; per VLAN, per port, and flow base; 2R3C policing

    Link Layer Discovery Protocol (LLDP) allows the switch to advertise its identification, configuration, and capabilities to neighboring devices that store the data in a 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. It also learns the connected device and its characteristics using Cisco Discovery Protocol.

    Product Specifications

    Power over Ethernet

    The following switches support 802.3at PoE+, 802.3af PoE, and Cisco prestandard (legacy) PoE on any of the RJ45 network ports. 60W PoE is also supported on selected RJ-45 network ports.

    Maximum power of 60W is delivered to any of the 60W PoE ports, and maximum power of 30W is delivered to any of the other RJ45 network ports, until the PoE budget for the switch is reached.

    The total power available for PoE per switch is as follows.
