Description
Occasion
HP 2530-48G J9775A 4SFP Gigabit Ethernet Switch (1000-Mbit/s)
Fully Managed
HP 2530-48G switches are fully managed Layer 2 edge switches, giving you
cost-effective, reliable and secure connectivity for enterprise networks.
Quality of Service (QoS)
Traffic priority management (IEEE 802.1p): allows traffic to be classified, in real time, 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: defines the maximum rates per input port for all input traffic, or for broadcast,
multicast or unknown destination traffic
Layer 4 Prioritization: Enables prioritization based on TCP/UDP port numbers
Management
Administrative interface options: Web GUI: User-friendly GUI based on
HTML allows you to configure the switch from any web browser. Command line (CLI): the interface of
Robust command line allows advanced configuration and diagnostics.
Simple Network Management Protocol (SNMPv1/v2c/v3): allows you to administer the switch using different applications
third-party network management services.
Virtual stack: a single IP address can manage up to 16 switches
sFlow (RFC 3176): Accounting and tracking traffic at wire speed configured by SNMP and CLI using three receivers
encrypted terminals
IEEE 802.1AB LLDP (Link Layer Discovery Protocol): Automated device discovery protocol for mapping
easy with network management applications
Logging: provides local and remote event logging via SNMP (v2c and v3) and syslog; prevents the
Log throttling and 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):
offers connectivity for both protocols; provides a transition mechanism from IPv4 to IPv6. MLD traffic monitoring:
redirects IPv6 multicast traffic to the correct interface; prevents IPv6 multicast traffic from overwhelming the network;
IEEE 802.3af Power over Ethernet Cable: Delivers up to 15.4W per port to power devices
power over Ethernet cable 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
Level 2 switching
VLAN: Provide support for 512 VLANs and 4094 VLAN IDs
Jumbo packet support: accepts frames of up to 9220 bytes. to improve transfer performance
large data
Table 16,000 MAC addresses: provides access to many layer 2 devices
GARP VLAN Registration Protocol: Enables automatic learning and dynamic VLAN assignment
Security
Access Control Lists: Supports one IPv4/IPv6 port and VLAN-based ACLs
Source port filtering: allows you to specify which ports are allowed to communicate with others
RADIUS/TACACS+: Facilitates security administration on the switch (password authentication server)
SSL protocol: encrypts all HTTP data exchanged, ensuring secure access to the based management user interface
on switch browser
Port Security: Allows access to specified MAC addresses only, which can be “learned” or specified
by 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 overflow of IP multicast traffic
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 link to increase bandwidth
bandwidth and create redundant connections. Supports L2, L3, and L3.L4 trunk load balancing algorithm
IEEE 802.3ad Link Aggregation Control Protocol (LACP): Facilitates configuration of hops through configuration
automatic.
Multiple Spanning Tree IEEE 802.1s: Provides high link availability in multiple VLAN environments by allowing
the use of several trees; enables support for older generation IEEE 802.1d and IEEE 802.1w protocols
