HPE Aruba Instant On 1930 48G 4SFP+ Switch (JL685A) - Инструкция по эксплуатации - Страница 4

DATA SHEET

SMART-MANAGED SWITCHES

NETWORK SECURITY

TPM-based security

Includes a Trusted Platform Module(TPM) for secure hardware-
based generation and storage of cryptographic keys used for 
secure connection to the Instant On cloud portal.

IEEE 802.1Q VLAN support

Support for up to 256 VLANs with a VLAN ID range of 2-4093

IEEE 802.1X access control

Authentication of network users on a per port basis prior to 
permitting network access. Port authentication includes RADIUS 
assigned VLAN, dynamic VLAN creation, guest VLAN or into an 
unauthenticated VLAN.

Automatic denial-of-service protection

Monitors for malicious attacks and protects the network by 
blocking the attacks.

Packet storm protection

Protects against unknown unicast, broadcast and multicast 
storms with user-defined thresholds.

RADIUS

The switch supports RADIUS authentication with primary and 
backup server configuration.

RADIUS accounting

A robust set of attributes and statistics are available for 
collecting information from the switch.

Management VLAN ID

Provides secure management access to administrators in the 
specified VLAN.

Link Flap prevention

Minimizes the network disruption by automatically detecting 
and disabling ports that experience link flap events.

PERFORMANCE AND EFFICIENCY

Energy Efficient Ethernet (EEE)

Compliant with IEEE 802.3az standard requirements to save 
energy during periods of low data activity.

Auto-port shut down

The switch saves power by automatically shutting down 
power to inactive ports. Power is restored on a port upon link 
detection.

Energy savings status

The switch provides an estimated cumulative energy savings 
due to green Ethernet features being enabled.

Energy-efficient cooling

Includes variable speed fans operating only at the speed 
necessary to maintain operating temperature to reduce excess 
noise and power consumption. 

Fan-less operation

Fan-less design for 8-port models, 24- and 48-port non-PoE 
models, making the switches ideal for office deployments.

SWITCHING Features

IEEE 802.3x Flow control

Provides a flow-throttling mechanism propagated through the 
network to prevent packet loss at a congested node.

Spanning Tree Protocol (STP)

Supports standard IEEE 802.1D STP, IEEE 802.1w Rapid 
Spanning Tree Protocol (RSTP) for faster convergence, and IEEE 
802.1s Multiple Spanning Tree Protocol (MSTP on local web).

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.

BPDU filtering

Drops BPDU packets when STP is enabled globally but disabled 
on a specific port.

Jumbo frame support

Supports up to 9216 bytes frame size to improve the 
performance of large data transfers.

IGMP snooping v1/v2

Improves network performance through multicast filtering, 
instead of flooding traffic on all ports.

Link aggregation

Groups together multiple ports up to a maximum of eight (8) 
ports per trunk automatically using Link Aggregation Control 
Protocol (LACP), or manually, to form a high-bandwidth 
connection to the network backbone that helps prevent traffic 
bottlenecks. The 8-port models support 4 trunks, 24-port 
models support 8 trunks, and 48-port models support 16 
trunks.
