Description
Tested and Functional Supplied with its Power Cable
HP 2530-48G Switch J9775A 4SFP Gigabit Ethernet (1000-Mbit/s)
Fully Managed
HP 2530-48G switches are fully managed layer 2 edge switches, providing you with a
cost-effective, reliable, and secure connectivity for enterprise networks.
Quality of Service (QoS)
Traffic priority management (IEEE 802.1p): allows real-time classification of traffic into eight priority levels
assigned to two or four queues; uses Weighted Deficit Round Robin (WDRR) or strict priority (SP)
Simplified QoS configuration: based on ports: prioritize traffic by specifying a port and a priority level.
VLAN-based: prioritize traffic by specifying a VLAN and a priority level.
Class of Service (CoS): defines an IEEE 802.1p priority marker based on IP address, Type of Service (ToS) IP,
layer 3 protocol, TCP/UDP port number, source port, and DiffServ
Rate limiting: defines maximum rates per input ports for all incoming traffic, or for broadcast,
multicast or unknown destination traffic
Layer 4 prioritization: enables prioritization based on TCP/UDP port numbers
Management
Administration interface options: Web user graphical interface: user-friendly graphical interface based on
HTML allows you to configure the switch from any web browser. Command line (CLI): the interface of
robust command line allows for advanced configuration and diagnostics.
Simple Network Management Protocol (SNMPv1/v2c/v3): allows you to manage the switch using various applications
third-party network management.
Virtual stack: a single IP address allows management of up to 16 switches
sFlow (RFC 3176): traffic accounting and monitoring at wire speed configured via SNMP and CLI through three receivers
encrypted terminals
IEEE 802.1AB LLDP (Link Layer Discovery Protocol): automated device discovery protocol for mapping
facilitated by network management applications
Logging: ensures local and remote logging of events via SNMP (v2c and v3) and syslog; prevents the
limiting and log filtering to reduce the number of log events generated
Connectors
IPv6: IPv6 Host: allows the switch to be deployed and managed at the edge of IPv6 networks; Dual stack (IPv4/IPv6):
provides connectivity for both protocols; offers a transition mechanism from IPv4 to IPv6. MLD traffic monitoring:
redirects IPv6 multicast traffic to the appropriate interface; prevents IPv6 multicast traffic from overwhelming the network;
Power over Ethernet IEEE 802.3af: provides up to 15.4 W per port to power devices
Power over Ethernet IEEE 802.3af, such as IP phones, wireless access points, and security cameras
Automatic MDIX: automatically adapts to straight or crossover cables on all ports
Layer 2 switching
VLAN: provides support for 512 VLANs and 4094 VLAN IDs
Support for Jumbo frames: accepts frames of up to 9220 bytes max. to enhance transfer performance
of large data
Table of 16,000 MAC addresses: provides access to numerous layer 2 devices
VLAN Registration Protocol GARP: allows for automatic learning and dynamic VLAN assignment
Safety
Access control lists: Supports an IPv4/IPv6 port and VLAN-based ACLs
Source port filtering : allows specifying the ports allowed to communicate with others
RADIUS/TACACS+ : facilitates security administration on the switch (password authentication server)
SSL Protocol : encrypts all exchanged HTTP data, ensuring secure access to the web-based management user interface
on the switch browser
Port security : allows access to only specified MAC addresses, which can be "learned" or indicated
by the administrator
Convergence
LLDP-MED (Media Endpoint Discovery) : is a standard extension of LLDP storing parameter values such as
QoS and VLAN to automatically configure network devices such as IP phones
IP multicast (data-driven IGMP) : automatically prevents IP multicast traffic overflow
IEEE 802.1AB LLDP (Link Layer Discovery Protocol) : is an automated device discovery protocol that ensures
an easy mapping of network management applications
Voice VLAN : uses LLDP-MED to automatically configure a VLAN for IP phones
Fault tolerance and high availability
Port link and link aggregation : Link: supports up to eight links per link to increase bandwidth
bandwidth and creates redundant connections. Supports the load balancing algorithm for trunk L2, L3, and L3.L4
IEEE 802.3ad LACP (Link Aggregation Control Protocol): facilitates the configuration of links through the configuration
automatic.
Multiple Spanning Tree IEEE 802.1s : offers high link availability in multiple VLAN environments by allowing
the use of multiple trees; allows support for legacy protocols IEEE 802.1d and IEEE 802.1w
