Aruba Instant On 1930 48G Class 4 PoE 4SFP/SFP+ 370W Switch (JL686B)

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.

LLDP/LLDP-MED (Media Endpoint Discovery)

Defines a standard extension of LLDP that stores values for parameters such as QoS and VLAN for automatic configuration of network devices such as IP phones.

Address Resolution Protocol (ARP)

The ARP table displays all of the IP addresses that have been resolved to MAC addresses, either dynamically or through static entry configuration.
