Model	SG350X-48-K9
Performance
Switching capacity and forwarding rate	Capacity in Mpps (64-byte packets): 130.94
Switching capacity and forwarding rate	Switching capacity (Gbps): 176
Layer 2 switching
Spanning Tree Protocol	Standard 802.1d spanning tree support Fast convergence using 802.1w (Rapid Spanning Tree Protocol [RSTP]), enabled by default 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
Power consumption (worst case)
Green power (mode)	EEE, Energy Detect, Short Reach
System power consumption	110V=51.6W 220V=51.4W
Heat dissipation (BTU/hr)	176.1
