Specifications
From The Manufacturer:
Cisco SG350-28SFP Switch Specifications:
| Model | SG350-28SFP |
| Capacity in Millions of Packets per Second (mpps) (64-byte packets) | 41.66 |
| Switching Capacity in Gigabits per Second (Gbps) | 56.0 |
| Layer 2 Switching | |
| Port grouping/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 link aggregation |
| 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 |
| Q-in-Q | VLANs transparently cross a service provider network while isolating traffic among customers |
| Unidirectional Link Detection (UDLD) | UDLD monitors the 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 |
| IGMP Querier | IGMP querier is used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast router |
| Head-Of-Line (HOL) blocking | HOL blocking prevention |
| Layer 3 | |
| IPv4 and IPv6 routing | Wirespeed routing of IPv4 packets
Up to 990 static routes and up to 128 IP interfaces Wirespeed routing of IPv6 packets |
| Layer 3 Interface | Configuration of Layer 3 interface on physical port, LAG, VLAN interface, or loopback interface |
| DHCP Server | Switch functions as an IPv4 DHCP server serving IP addresses for multiple DHCP pools/scopes
Support for DHCP options |
| User Datagram Protocol (UDP) relay | Relay of broadcast information across Layer 3 domains for application discovery or relaying of bootP/DHCP packets |
| Security | |
| Secure Shell (SSH) Protocol | SSH is a secure replacement for Telnet traffic. SCP also uses SSH. SSH v1 and v2 are supported |
| Web-based authentication | Web-based authentication provides network admission control through a web browser to any host devices and operating systems |
| STP loopback guard | Provides additional protection against Layer 2 forwarding loops (STP loops) |
| 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 |
| Private VLAN | Private VLAN 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 |
| Storm control | Broadcast, multicast, and unknown unicast |
| Quality of Service | |
| Priority levels | 8 hardware queues |
| Class of service | Port-based; 802.1p VLAN priority based; IPv4/v6 IP precedence/Type of Service (ToS)/DSCP based; Differentiated Services (DiffServ); classification and remarking ACLs, Trusted QoS
Queue assignment based on DSCP and class of service (802.1p/CoS) |
| Standards | |
| IPv6 QoS | Prioritize IPv6 packets in hardware |
| Multicast Listener Discovery (MLD v1/2) snooping | Deliver IPv6 multicast packets only to the required receivers |
| Management | |
| Web user interface | Built-in switch configuration utility for easy browser-based device configuration (HTTP/HTTPS)
Supports simple and advanced modes, configuration, wizards, customizable dashboard, system maintenance, monitoring, online help, and universal search |
| Port mirroring | Traffic on a port can be mirrored to another port for analysis with a network analyzer or RMON probe. Up to 8 source ports can be mirrored to one destination port. A single session is supported |
| Localization | Localization of GUI and documentation into multiple languages |
| Power consumption (worst case)
Green Power (mode) |
EEE, Energy Detect, Short Reach |
| Total System Ports | 28 Gigabit Ethernet |
| Packet Buffer | 1.5 MB |
| Unit Dimensions | 440 x 44 x 203 mm (17.3 x 1.73 x 7.99 in) |
| Unit Weight | 2.7 kg (5.95 lb) |
| Power | 100-240V 50-60 Hz, internal, universal |
| Operating temperature | 32° to 122°F (0° to 50°C) |
| Acoustic noise and MTBF
FAN (Number) |
1 |
