classification; packets are mapped to six hardware queues for more effective throughput
• IEEE 802.1p/Q VLAN tagging
Delivers data to devices based on the priority and type of traffic; supports IEEE 802.1Q
• Advanced classifier based QoS
Classifies traffic using multiple match criteria based on Layer 2, 3, and 4 information.
• Packet storm protection
Protects against unknown unicast, broadcast and multicast storms with user-defined thresholds
• Rate limiting
Sets per-port ingress enforced maximums or percent minimum bandwidth per queue
• Class of Service (CoS)
Sets the IEEE 802.1p priority tag based on IP address, IP Type of Service (ToS), Layer 3 protocol, TCP/UDP port number
or source port
• Powerful QoS feature
Supports the following congestion actions: strict priority queuing (SP) or weighted round robin (WRR) queuing. SP and
WRR queuing can be configured on individual switch ports.
Connectivity
• IPv6 host
Enables switches to be managed and deployed at the IPv6 network’s edge
• IEEE 802.3X Flow Control
Provides a flow throttling mechanism propagated through the network to prevent packet loss at a congested node
• IEEE 802.3at Power over Ethernet (PoE+)
Provides up to 30 W per port, which allows support of the latest PoE+ capable devices such as Video IP phones, wireless
access points, and advanced pan/tilt/zoom security cameras, as well as any 15.4 W IEEE 802.3af-compliant end device;
mitigates the cost of additional electrical cabling and circuits that would otherwise be necessary in IP phone and WLAN
deployments
• PoE+ port availability
Ports 1–4 are PoE/PoE+ capable on the HPE OfficeConnect 1920S 8G PPoE+ 65W switch; ports 1–12 are PoE/PoE+
capable on the HPE OfficeConnect 1920S 24G 2SFP PPoE+ 185W switch; all ports provide PoE/PoE+ on the HPE
OfficeConnect 1920S 24G 2SFP PoE+ 370W switch; ports 1–24 are PoE/PoE+ capable
on the HPE OfficeConnect 1920S
48G 4SFP PPoE+ 370W switch
• Auto-PoE power configuration
The switch automatically assigns the required power to a port for a PD device based on Link Layer Discovery Protocol
(LLDP). Optionally, the switch permits manual, per port, PoE power configuration
• PoE shut down mode
A PoE scheduler provides the ability to define the hours of PoE power being supplied to a group of switch ports based on
a 24-hour day. The scheduler enables the flexibility to select individual days of a we
ek as well as reoccurrence on a weekly
basis with a start and end date.
• PoE power allocation
Support multiple methods (automatic, IEEE 802.3af class, LLDP-MED, or user-specified) to allocate PoE power for more
efficient energy savings
• SPF ports for fiber connectivity
Provides fiber connections for uplinks and other connections across longer distances than copper cabling can support;
SFP ports are in addition to available copper Ethernet ports, providing a higher total number of available ports. Two SFP
ports available on 24 and four SFP ports on 48 port models
• Loop protection
If the switch detects a loop, it disables the source port from forwarding data packets originating from the switch to avoid
broadcast storms
• Auto MDI/MDI-X
Adjusts automatically for straight-through or crossover cables on all 10/100/1000 ports
• Energy Efficient Ethernet (EEE)
Compliant with IEEE 802.3az standard requirements to save energy during periods of low data activity
• Auto-port shut down
