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, offering you
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: port-based: prioritize traffic by specifying a port and priority level.
VLAN-based: prioritize traffic by specifying a VLAN and priority level.
Class of Service (CoS): defines an IEEE 802.1p priority marker based on IP address, IP type of service (ToS),
layer 3 protocol, TCP/UDP port number, source port, and DiffServ
Rate limiting: sets maximum input rates per port 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 graphical user interface: user-friendly GUI based on
HTML allows configuring the switch from any web browser. Command Line Interface (CLI): the interface for
robust command line allows advanced configuration and diagnostics.
Simple Network Management Protocol (SNMPv1/v2c/v3): allows managing the switch using various applications
third-party network management.
Virtual stack: a single IP address can manage up to 16 switches
sFlow (RFC 3176): traffic accounting and monitoring at wire speed configured via SNMP and CLI using 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 event logging via SNMP (v2c and v3) and syslog; prevents
limiting and log filtering to reduce the number of generated log events
Connectors
IPv6: IPv6 host: allows the switch to be deployed and managed at the edge of IPv6 networks; Dual stack (IPv4/IPv6):
offers connectivity for both protocols; provides 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
Auto MDIX: automatically adapts to straight or crossover cables on all ports
Layer 2 switching
VLAN: supports 512 VLANs and 4094 VLAN IDs
Jumbo packet support: accepts frames up to 9220 bytes max. to improve transfer performance
large data
16,000 MAC address table: provides access to many layer 2 devices
GARP VLAN Registration Protocol: enables automatic learning and dynamic VLAN assignment
Security
Access control lists: Supports IPv4/IPv6 port and VLAN-based ACLs
Source port filtering: allows specifying ports authorized 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 management user interface based on
on the switch browser
Port security: allows access only to specified MAC addresses, which can be “learned” or manually specified
by the administrator
Convergence
LLDP-MED (Media Endpoint Discovery): is a standard LLDP extension 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
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 bonding and link aggregation: Bonding: supports up to eight links per bond to increase bandwidth
pass-through and create redundant connections. Supports L2, L3, and L3.L4 trunk load balancing algorithms
IEEE 802.3ad LACP Protocol (Link Aggregation Control Protocol): facilitates trunk configuration via pass-through configuration and creates redundant connections. Supports L2, L3, and L3.L4 trunk load balancing algorithms
automatic.
Multiple Spanning Tree IEEE 802.1s: provides high link availability across multiple VLAN environments by allowing
The use of multiple spanning trees; supports legacy protocols IEEE 802.1d and IEEE 802.1w
