Guest VLAN Unauthenticated VLAN Protocol-based VLAN CPE VLAN

Dynamic VLAN assignment via Radius server along with 802.1x client authentication

Voice VLAN

Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS. Auto voice capabilities deliver network-wide zero touch deployment of voice endpoints and call control devices.

Multicast TV VLAN

Multicast TV VLAN allows the single multicast VLAN to be shared in the network while subscribers remain in separate VLANs. This feature is also known as Multicast VLAN Registration (MVR).


VLANs transparently cross over a service provider network while isolating traffic among customers.


Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP) enable automatic propagation and configuration of VLANs in a bridged domain.

Unidirectional Link Detection (UDLD)

UDLD monitors physical connection to detect unidirectional links caused by incorrect wiring or port faults to prevent forwarding loops and blackholing of traffic in switched networks

DHCP Relay at Layer 2

Relay of DHCP traffic to DHCP server in a different VLAN. Works with DHCP Option 82.

IGMP (versions 1, 2, and 3)

Internet Group Management Protocol (IGMP) limits bandwidth-intensive multicast traffic to only the requesters; supports 1K (1024) and 4K (for SG500X in native mode) multicast groups (source-specific multicasting is also supported).

IGMP querier

IGMP querier is used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast router.

HOL blocking

Head-of-line (HOL) blocking.

Jumbo Frames

Frames up to 9K (9216) bytes in length.

Layer 3

IPv4 routing

Wirespeed routing of IPv4 packets

Up to 2K (2048) static routes and up to 256 IP interfaces

Wirespeed IPv6 Static Routing

Up to 2K (2048) static routes and up to 128 IPv6 interfaces

Layer 3 Interface

Configuration of layer 3 interface on physical port, LAG, VLAN interface or Loopback interface


Support for Classless Inter-Domain Routing

RIP v2 (on 500X)

Support for Routing Information Protocol version 2, for dynamic routing

VRRP (on 500X)

Virtual Router Redundancy Protocol (VRRP) delivers improved availability in a Layer 3 network by providing redundancy of the default gateway servicing hosts on the network. VRRP versions 2 and 3 are supported. Up to 255 virtual routers are supported.

DHCP Server

Switch functions as an IPv4 DHCP Server serving IP addresses for multiple DHCP pools/scopes

Support for DHCP options

DHCP Relay at Layer 3

Relay of DHCP traffic across IP domains.

User Datagram Protocol (UDP) Relay

Relay of broadcast information across Layer 3 domains for application discovery or relaying of BOOTP/DHCP packets.


Hardware stack

Up to 8 units in a stack. Up to 416 ports managed as a single system with hardware failover.

High availability

Fast stack failover delivers minimal traffic loss.

Plug-and-play stacking configuration/management

Master/backup for resilient stack control


Hot swap of units in stack

Ring and chain stacking options Auto stacking port speed Flexible stacking port options

High-speed stack interconnects

Cost-effective 5G copper and high-speed 10G Fiber and Copper interfaces.

Hybrid stack

A mix of SF500, SG500, and SG500X in the same stack (10/100, Gigabit, and 10 Gigabit).



SSH is a secure replacement for Telnet traffic. SCP also uses SSH. SSH versions 1 and 2 are supported.


Secure Sockets Layer (SSL) encrypts all HTTPS traffic, allowing secure access to the browser-based management GUI in the switch.

IEEE 802.1X (Authenticator role)

RADIUS authentication and accounting, MD5 hash, guest VLAN, unauthenticated VLAN, single/multiple host mode and single/multiple sessions

Supports time-based 802.1X Dynamic VLAN assignment

Web Based Authentication

Web based authentication provides network admission control through web browser to any host devices and operating systems.


A security mechanism to protect the networks from invalid configurations. A port enabled for Bridge Protocol Data Unit (BPDU) Guard is shut down if a BPDU message is received on that port. This avoids accidental topology loops.

STP Root Guard

This prevents edge devices not in the network administrator’s control from becoming Spanning Tree Protocol root nodes.

DHCP snooping

Filters out DHCP messages with unregistered IP addresses and/or from unexpected or untrusted interfaces. This prevents rogue devices from behaving as a DHCP Server.

IP Source Guard (IPSG)

When IP Source Guard is enabled at a port, the switch filters out IP packets received from the port if the source IP addresses of the packets have not been statically configured or dynamically learned from DHCP snooping. This prevents IP Address Spoofing.

Dynamic ARP Inspection (DAI)

The switch discards ARP packets from a port if there are no static or dynamic IP/MAC bindings or if there is a discrepancy between the source or destination address in the ARP packet. This prevents man-in-the-middle attacks.

IP/Mac/Port Binding (IPMB)

The features (DHCP Snooping, IP Source Guard, and Dynamic ARP Inspection) above work together to prevent DoS attacks in the network, thereby increasing network availability

Secure Core Technology (SCT)

Ensures that the switch will receive and process management and protocol traffic no matter how much traffic is received.

Secure Sensitive Data (SSD)

A mechanism to manage sensitive data (such as passwords, keys, etc.) securely on the switch, populating this data to other devices, and secure autoconfig. Access to view the sensitive data as plaintext or encrypted is provided according to the user configured access level and the access method of the user.

Layer 2 isolation (PVE) with community VLAN*

Private VLAN Edge provides security and isolation between switch ports, which helps ensure that users cannot snoop on other users’ traffic; supports multiple uplinks.

Port security

Ability to lock Source MAC addresses to ports, and limit the number of learned MAC addresses.


Supports RADIUS and TACACS authentication. Switch functions as a client.

RADIUS accounting

The RADIUS accounting functions allow data to be sent at the start and end of services, indicating the amount of resources (such as time, packets, bytes, and so on) used during the session.

Storm control

Broadcast, multicast, and unknown unicast.

DoS prevention

Denial-of-Service (DoS) attack prevention.

Multiple user privilege levels in CLI

Levels 1, 7, and 15 privilege levels.


Support for up to 2K (2048) rules on 500 Series and 3K (3072) on 500X series.

Drop or rate limit based on source and destination MAC, VLAN ID or IP address, protocol, port, DSCP/IP precedence, TCP/User Datagram Protocol (UDP) source and destination ports, 802.1p priority, Ethernet type, Internet Control Message Protocol (ICMP) packets, Internet Group Management Protocol (IGMP) packets, TCP flag.

Ce primesti in cutie cand cumperi de la noi

Servere Refurbished

Serverul este selectat din depozit si adus in zona de asamblare impreuna cu restul componentelor necesare in configuratia comandata.


Aici serverul este verificat si curatat profesional. Urmeaza montarea cu atentie a componentelor si pornirea sistemului. Se instaleaza absolut toate componentele din configuratie. Procesoarele sunt instalate cu atentie in socket-uri si acoperite cu pasta termica termica Arctic MX-2


Memoriile sunt instalate tinand cont de modul corect de populare al canalelor de memorie recomandat de producatorul serverului.


Se monteaza hard disk-urile si ssd-urile in caddy pentru a fi montate in bay-uri. Se monteaza eventualele placi de extensie PCI sau LOM-uri.



Se porneste serverul, se reseteaza BIOS-ul si sistemul de management al serverului. Se urmareste realizarea unui POST fara erori sau alerte. Dupa POST, se trece la realizarea update-ului de firmware pe intreaga platforma, folosing cele mai recente  biblioteci de firmware puse la dispozitie de producatori.

Dupa ce s-a relizat actualizarea de firmware se face test complet al configuratiei folosind sofurile integrate in server, pentru a asigura o buna functionalitate a intregului ansamblu.



Daca toate testele se realizeaza fara erori se trece la ambalarea sistemului. Pentru impachetare folosim cutii de carton realizate special pentru servere a.i sa fie cat mai apropiate de cutiile originale. Serverele sunt protejate in cutie folosing confectii din spuma de polipropilena si alte elemete pentru umplerea golurilor. In felul acesta ne asiguram ca sistemul ajunge la tine in cele mai bune conditii.
