Aruba 2530 48G Switch (J9775A)

48 RJ-45 autosensing 10/100/1000 ports (IEEE 802.3 Type 10BASE-T, IEEE 802.3u Type 100BASE-TX, IEEE 802.3ab Type 1000BASE-T); Duplex: 10BASE-T/100BASE-TX: half or full; 1000BASE-T: full only

4 fixed Gigabit Ethernet SFP ports
(H) 4.45 cm x (W) 44.30 cm x (D) 25.40 cm (1.75” x 17.44” x 10.00”) (1U height)
Weight: 6.8 lb (3.08 kg)
Traffic prioritization (IEEE 802.1p) allows real-time traffic classification with support for eight priority levels mapped to either two or four queues, and uses weighted deficit round robin (WDRR) or strict priority
Simplified quality of service (QoS) configuration

Port-based prioritizes traffic by specifying a port and priority level
VLAN-based prioritizes traffic by specifying a VLAN and priority level
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, source port, and DiffServ
Rate limiting establishes per-port ingress-enforced maximums for all ingressed traffic or for broadcast, multicast, or unknown destination traffic
Layer 4 prioritization enables prioritization based on TCP/UDP port numbers
Flow control helps deliver reliable communication during full-duplex operation
