Valdomi (managed) komutatoriai suteikia galimybę valdyti duomenų perdavimą vidiniame tinkle bei jų valdymą. Nevaldomi komutatoriai tiesiog suteikia galimybę dviems įrenginiams, Ethernet jungties pagalba, pvz., kompiuteriui ir spausdintuvui sąveikauti. Įprastai tokio tipo įrenginiai vadinami «Plug-and-Play».

Tinklo standartai
Belaidžio ryšio perdavimo standartai. 802.11G vis dar nenorinti pasiduoti senoji technologija technologija. Mat G standarto adapterius turi dauguma prieš kelerius metus pagamintų nešiojamųjų kompiuterių. Ryšys veikia 2,4 GHz bangų diapazonu. Teorinė jo sparta siekia 54 MB/s, kas šiais laikais yra gerokai per mažai. 802.11ac – tai naujas belaidžio ryšio standartas, užtikrinantis didelį perduodamų duomenų greitį 5 GHz dažnio intervale. Dėl to garantuojamas trukdžių ir užlaikymų nebuvimas, kai perduodamas srautinis HD video vaizdas, atliekami video skambučiai, veikia VoIP telefonija ar žaidžiami žaidimai. 802.11ac užtikrina spartų duomenų duomenų perdavimą iki 1,3 Gb/s sparta – trigubai greičiau negu naudojant ankstesnį 802.11n standartą.

Tinklo (LAN) jungčių greitis
LAN arba Ethernet jungtis tinklo kabeliui pajungti. 10/100 MB/s standartinis greitis, kuris būdingas beveik visiems maršrutizatoriams. 10/100/1000 MB/s arba GigaBit standartas dešimt kartų greitesnis, kuris kartu su Gigabit LAN tinklo plokštės pagalba leidžia vidiniame kompiuterių tinkle duomenis perduoti itin greitai. Toks sprendimas yra būtinas biuruose, kur tarp kompiuterių reikia dažnai nukopijuoti didelės apimties failus arba reikalingas spartus plačiajuostis interneto ryšys (su ~30 Mb/s) keliuose kompiuteriuose vienu metu.

Specifications:

Product overview
The HP 2530 Switch Series consists of four fully managed Layer 2 edge switches, delivering cost-effective, reliable, and secure connectivity for business networks. Designed for entry-level to midsize enterprise networks, these Gigabit Ethernet switches deliver full Layer 2 capabilities with enhanced access security, traffic prioritization, IPv6 host support, and optional PoE+, and include a product lifetime warranty.

Each 2530 switch has 24 or 48 RJ-45 10/100/1000 ports and four small form-factor pluggable (SFP) slots for fiber connectivity. For customers implementing Power over Ethernet for voice, video, or wireless deployments, the HP 2530-24G-PoE+ and the HP 2530-48G-PoE+ Switches are IEEE 802.3af and IEEE 802.3at compliant with up to 30 W per port.

The HP 2530 Switch Series is easy to use, deploy, and manage via SNMP, CLI, and Web GUI. The series offers flexible wall, table, and rack mounting; quiet operation; and improved power savings, with features such as IEEE 802.3 az (Energy Efficient Ethernet). These switches include a lifetime warranty and all software releases and technical phone support.

  • 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) — 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 — sets 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
Management

  • Power and fault LEDs — display any issues
Connectivity
  • IPv6 host — allows the switch to be deployed and managed at the edge of an IPv6 network
  • Dual stack (IPv4/IPv6) — supports connectivity for both protocols; provides a transition mechanism from IPv4 to IPv6
  • MLD snooping — forwards IPv6 multicast traffic to the appropriate interface; prevents IPv6 multicast traffic from flooding the network

  • Auto-MDIX — adjusts automatically for straight-through or crossover cables on all ports
  • Pre-standard PoE support — detects and provides power to pre-standard PoE devices; see list of supported devices in the product FAQ at www.hp.com/networking/support
  • Small Form-Factor Pluggable (SFP) slots — provides fiber connectivity such as Gigabit-SX, -LX, -LH, and -BX with four SFP slots
  • Dual-personality (RJ-45 or USB micro-B) serial console port — gives easy access to switch CLI via front switch location of dual-personality RJ-45 or USB micro-B serial console port
Layer 2 switching
  • VLANs — provide support for 512 VLANs and 4,094 VLAN IDs
  • Jumbo packet support — supports up to 9220-byte frame size to improve the performance of large data transfers

  • GARP VLAN Registration Protocol — allows automatic learning and dynamic assignment of VLANs
Security
  • Access control lists (ACLs) — accomnodates IPv4/IPv6 port and VLAN-based ACLs
  • Source-port filtering — allows only specified ports to communicate with each other
  • RADIUS/TACACS+ — eases switch management security administration by using a password authentication server

  • Port security — allows access only to specified MAC addresses, which can be learned or specified by the administrator
  • MAC address lockout — prevents particular configured MAC addresses from connecting to the network
  • Multiple user authentication methods —
  • IEEE 802.1X — is an industry-standard method of user authentication using an IEEE 802.1X supplicant on the client in conjunction with a RADIUS server
  • Web-based authentication — similar to IEEE 802.1X, it provides a browser-based environment to authenticate clients that do not support the IEEE 802.1X supplicant
  • MAC-based authentication — authenticates the client with the RADIUS server based on the client's MAC address
  • Secure Shell (SSHv2) (client and server) — encrypts all transmitted data for secure, remote CLI access over IP networks
  • Secure Shell — encrypts all transmitted data for secure remote CLI access over IP networks
  • STP BPDU port protection — blocks Bridge Protocol Data Units (BPDUs) on ports that do not require BPDUs, preventing forged BPDU attacks
  • STP Root Guard — protects the root bridge from malicious attacks or configuration mistakes
  • Secure management access — securely encrypts all access methods (CLI, GUI, or MIB) through SSHv2 and SNMPv3
  • Custom banner — displays security policy when users log in to the switch
  • Secure FTP — allows secure file transfer to and from the switch; protects against unwanted file downloads or unauthorized copying of a switch configuration file
  • Protected ports CLI — offers intuitive CLI to configure the source-port filters feature by allowing specified ports to be isolated from all other ports on the switch; the protected port or ports can communicate only with the uplink or shared resources
Authentication flexibility —
  • Multiple IEEE 802.1X users per port — provides authentication of up to eight IEEE 802.1X users per port; prevents user "piggybacking" on another user's IEEE 802.1X authentication
  • Concurrent IEEE 802.1X and Web or MAC authentication schemes per port — switch port will accept any of IEEE 802.1X and either Web or MAC authentications
  • Switch management logon security — helps secure switch CLI logon by optionally requiring either RADIUS or TACACS+ authentication
Convergence
