Multiple spanning tree instances using 802.1s (MSTP); 8 instances are supported

Per-VLAN Spanning Tree Plus (PVST+); 126 instances are supported

Rapid PVST+ (RPVST+); 126 instances are supported

Port grouping and link aggregation

Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP)

– Up to 8 groups

– Up to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad LAG

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

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)

VLAN translation

Support for VLAN One-to-One Mapping. In VLAN One-to-One Mapping, on an edge interface, Customer VLANs (C-VLANs) are mapped to service provider VLANs (S-VLANs) and the original C-VLAN tags are replaced by the specified S-VLAN

Q-in-Q

VLANs transparently cross over a service provider network while isolating traffic among customers

Selective Q-in-Q

Selective Q-in-Q is an enhancement to the basic Q-in-Q feature and provides, per edge interface, multiple mappings of different C-VLANs to separate S-VLANs

Selective Q-in-Q also allows configuration of the EtherType (TPID) of the S-VLAN tag

Layer 2 protocol tunneling over Q-in-Q is also supported

GVRP/GARP

Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP) enable automatic propagation and configuration of VLANs in a bridged domain

UDLD

Unidirectional Link Detection (UDLD) monitors physical connections 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 a 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; it supports 4000 multicast groups (source-specific multicasting is also supported)

IGMP querier

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 990 static routes and up to 128 IP interfaces

Wirespeed IPv6 static routing

Up to 245 static routes and up to 106 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 (CIDR)

DHCP server

Switch functions as an IPv4 DHCP server serving IP addresses for multiple DHCP pools and 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

Stacking

Hardware stack

Up to four units in a stack. Up to 208 ports managed as a single system with hardware failover

High availability

Fast stack failover delivers minimal traffic loss. Supports link aggregation across multiple units in a stack

Plug-and-play stacking configuration and management

Master and backup for resilient stack control

Auto-numbering

Hot swap of units in stack

Ring and chain stacking options, auto-stacking 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

Hybrid stack

A mix of SG350X, SG350XG, and SX350X switches in the same stack (Gigabit and 10 Gigabit Ethernet)

Security

SSH

Secure Shell (SSH) is a secure replacement for Telnet traffic. Secure Copy (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- and multiple-host mode, and single and multiple sessions

Supports time-based 802.1X dynamic VLAN assignment

IEEE 802.1X supplicant

A switch can be configured to act as a supplicant to another switch. This enables extended secure access in areas outside the wiring closet (such as conference rooms)

Web-based authentication

Web-based authentication provides Network Admission Control (NAC) through a web browser to any host devices and operating systems

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, Type of Service (ToS), and 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 based; Two-Rate Three-Color (2R3C) policing

Congestion avoidance

A TCP congestion avoidance algorithm is required to minimize and prevent global TCP loss synchronization

iSCSI traffic optimization

A mechanism for giving priority to SCSI over IP (iSCSI) traffic over other types of traffic
