8 instances are supported
Multiple Spanning Tree instances using 802.1s (MSTP)
Port groupingSupport 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 link aggregation
VLANSupport for up to 4096 VLANs simultaneously
Port-based and 802.1Q tag-based VLANs
MAC-based VLAN
Management VLAN
Private VLAN Edge (PVE), also known as protected ports, with multiple uplinks
Guest VLAN
Unauthenticated VLAN
Dynamic VLAN assignment via RADIUS server along with 802.1x client authentication
CPE VLAN
Voice VLANVoice 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 VLANMulticast TV VLAN allows the single multicast VLAN to be shared in the network while subscribers remain in separate VLANs (also known as MVR)
Q-in-Q VLANVLANs transparently cross a service provider network while isolating traffic among customers
Generic VLAN Registration Protocol (GVRP)/Generic Attribute Registration Protocol (GARP)Protocols for automatically propagating and configuring 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 blackholing of traffic in switched networks
Dynamic Host Configuration Protocol (DHCP) Relay at Layer 2Relay of DHCP traffic to DHCP server in different VLAN; works with DHCP Option 82
Internet Group Management Protocol (IGMP) versions 1, 2, and 3 snoopingIGMP limits bandwidth-intensive multicast traffic to only the requesters; supports 4K multicast groups (source-specific multicasting is also supported)
IGMP QuerierIGMP querier is used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast router
Head-Of-Line (HOL) blockingHOL blocking prevention
Loopback DetectionLoopback 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 routingWirespeed routing of IPv4 packets
Up to 7K routes and up to 256 IP interfaces
Wirespeed IPv6 static routingUp to 7K routes and up to 256 IPv6 interfaces
Layer 3 interfaceConfiguration of Layer 3 interface on physical port, LAG, VLAN interface, or loopback interface
CIDRSupport for classless interdomain routing
RIP v2Support for Routing Information Protocol version 2 for dynamic routing
VRRPVirtual 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 serverSwitch functions as an IPv4 DHCP server serving IP addresses for multiple DHCP pools/scopes.
Support for DHCP options
DHCP relay at Layer 3Relay of DHCP traffic across IP domains
User Datagram Protocol (UDP) relayRelay of broadcast information across Layer 3 domains for application discovery or relaying of BOOTP/DHCP packets
Security
SSHSSH is a secure replacement for Telnet traffic. SCP also uses SSH. SSH versions 1 and 2 are supported.
SSLSecure 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 authenticationWeb-based authentication provides network admission control through web browser to any host devices and operating systems.
STP BPDU GuardA 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 GuardThis prevents edge devices not in the network administrator’s control from becoming Spanning Tree Protocol root nodes.
DHCP snoopingFilters 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 VLANPrivate VLAN provides security and isolation between switch ports, which helps ensure that users cannot snoop on other users’ traffic; supports multiple uplinks.
Port securityAbility 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 accountingThe 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 controlBroadcast, multicast, and unknown unicast.
DoS preventionDenial-of-service (DoS) attack prevention.
Multiple user privilege levels in CLILevel 1, 7, and 15 privilege levels.
ACLsSupport for up to 2K entries on SG550XG models.
Support for up to 3K entries on all other models.
