    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.

    DHCP Relay at Layer 2

    Relay of DHCP traffic to DHCP server in a different VLAN. Works with DHCP Option 82.

    Jumbo Frames

    Frames up to 9K (9216) bytes in length.

    Layer 3

    IPv4 routing

    Wirespeed routing of IPv4 packets Up to 2K (2048) static routes and up to 256 IP interfaces

    Wirespeed IPv6 Static Routing

    Up to 2K (2048) static routes and up to 128 IPv6 interfaces

    Layer 3 Interface

    Configuration of layer 3 interface on physical port, LAG, VLAN interface or Loopback interface

    RIP v2 (on 500X)

    Support for Routing Information Protocol version 2, for dynamic routing

    DHCP Server

    Switch functions as an IPv4 DHCP Server serving IP addresses for multiple DHCP pools/scopesSupport for DHCP options

    Stacking

    Hardware stack

    Up to 8 units in a stack. Up to 416 ports managed as a single system with hardware failover.

    High availability

    Fast stack failover delivers minimal traffic loss.

    Plug-and-play stacking configuration/management

    Master/backup for resilient stack controlAuto-numberingHot swap of units in stackRing and chain stacking options Auto stacking port speed Flexible stacking port options

    High-speed stack interconnects

    Cost-effective 5G copper and high-speed 10G Fiber and Copper interfaces.

    Hybrid stack

    A mix of SF500, SG500, and SG500X in the same stack (10/100, Gigabit, and 10 Gigabit).

    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 sessionsSupports 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 features (DHCP Snooping, IP Source Guard, and Dynamic ARP Inspection) above work together to prevent DoS attacks in the network, thereby increasing network availability

    Secure Core Technology (SCT)

    Ensures 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, etc.) 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 (PVE) with community VLAN*

    Private VLAN Edge 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

    Levels 1, 7, and 15 privilege levels.

    ACLs

    Support for up to 2K (2048) rules on 500 Series and 3K (3072) on 500X series.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.
