Layer 2 Switching

Spanning Tree Protocol

Standard 802.1d Spanning Tree SupportFast convergence using 802.1w (Rapid Spanning Tree [RSTP]), enabled by defaultMultiple spanning tree instances using 802.1s (MSTP). 16 instances are supported

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


Support for up to 4096 VLANs simultaneously Port-based and 802.1Q tag-based VLANs MAC-based VLANManagement VLANPVE (Private VLAN Edge), also known as Protected Port, with multiple uplinksGuest VLAN Unauthenticated VLAN Protocol-based VLAN CPE VLAN Dynamic VLAN assignment via Radius server along with 802.1x client authentication

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


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).



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


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.


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.


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.


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.

Time-based ACLs supported.

Pv4 and IPv6 Dual Stack

Coexistence of both protocol stacks to ease migration
