- Model SG350X-24P-K9-EU
- Performance
- Switching capacity and forwarding rate Capacity in Mpps (64-byte packets): 95.23
- Switching capacity (Gbps): 128
- 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 over Ethernet
