ПРОДАМ: 3com 4500G

[Haxxproxx! 0]

В связи с расширением одного из провайдера продается очень хороший коммутатор 3 уровня. 3COM 4500G-3CR17761-91
 
Проработал годик в серверной, состояние нового, не вскрывался, не ремонтировался. На фото видна заводская наклейка
 
4 вентилятора при работе не шумят практически, при загрузки из бута сильно вращаются из-за теста.

 

Цена: 2700 грн.

Если вдруг кто не знает напомню, что это - гигабитный 24 портовый, полноценный L3 коммутатор.

 

 

Quality of Service (QoS)

• Layer 4 prioritization — enables prioritization based on TCP/UDP port numbers
• Traffic prioritization (IEEE 802.1p) — allows real-time traffic classification into eight priority levels mapped to eight queues
• 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 and per-port, per-queue guaranteed minimums
• Bandwidth shaping —
  • Rate limiting — provides per-port, ingress-based enforced bandwidth maximums
  • Guaranteed minimums — provides per-port, per-queue egress-based guaranteed bandwidth minimums
• Broadcast control — allows limitation of broadcast traffic rate to cut down on unwanted network broadcast traffic

Management

• Remote configuration and management — is available through a secure Web browser or a command-line interface (CLI)
• Manager and operator privilege levels — enable read-only (operator) and read/write (manager) access on CLI and Web browser management interfaces
• Management VLAN — segments traffic to and from management interfaces, including CLI/telnet, a Web browser interface, and SNMP
• RADIUS accounting support — separates RADIUS accounting server support per SSID; provides detailed session, usage, and billing information for each client activity
• Multiple configuration files — can be stored to the flash image
• Dual flash images — provide independent primary and secondary operating system files for backup while upgrading
• Secure Web GUI — provides a secure, easy-to-use graphical interface for configuring the module via HTTPS
• Command-line interface (CLI) — provides a secure, easy-to-use command-line interface for configuring the module via SSH or a switch console; provides direct real-time session visibility
• SNMPv1, v2c, and v3 — facilitate centralized discovery, monitoring, and secure management of networking devices
• Port mirroring — enables traffic on a port to be simultaneously sent to a network analyzer for monitoring
• 3Com-heritage Comware Operating System — CLI and Web user interface in common with HP 4XXX and 55XX series switches

Connectivity

• Auto-MDIX — automatically adjusts for straight-through or crossover cables on all 10/100 and 10/100/1000 ports
• Dual-personality functionality — includes four 10/100/1000 ports or SFP slots for optional fiber connectivity such as Gigabit-SX, -LX, and -LH, or 100-FX
• IEEE 802.3af Power over Ethernet (PoE) — provides up to 15.4 W per port to IEEE 802.3af-compliant PoE-powered devices such as IP phones, wireless access points, and security cameras
• Optional 10 GbE ports — through the use of optional modules, additional 10 GbE connections are available for uplinks or high-bandwidth server connections; flexibly supports XFP, SFP+, or CX4 local connections

Manageability

• RMON (remote monitoring) — provides advanced monitoring and reporting capabilities for statistics, history, alarms, and events
• Dual flash images — provides independent primary and secondary operating system files for backup while upgrading
• Full-featured console — provides complete control of the switch with a familiar command-line interface (CLI)
• Web interface — allows configuration of the switch from any Web browser on the network
• Multiple configuration files — allow multiple configuration files to be stored to a flash image
• Software updates — free downloads from the Web
• sFlow (RFC 3176) — wire-speed traffic accounting and monitoring
• Virtual stacking capability — single IP address management for a virtual stack of up to 255 Comware-based 3Com legacy devices, including HP 4XXX and 55XX series switches

Layer 2 switching

• VLAN support and tagging — support IEEE 802.1Q with 4,094 simultaneous VLAN IDs
• GARP VLAN Registration Protocol — allows automatic learning and dynamic assignment of VLANs
• IP multicast snooping and data-driven IGMP — automatically prevents flooding of IP multicast traffic
• Jumbo packet support — supports up to 9220-byte frame size to improve the performance of large data transfers
• IEEE 802.1ad QinQ — increases the scalability of an Ethernet network by providing a hierarchical structure; connects multiple LANs on a high-speed campus or metro network

Layer 3 routing

• Static IP routing — provides manually configured routing; includes ECMP capability
• Routing Information Protocol (RIP) — provides RIPv1 and RIPv2 routing

Back to top

 

Security

• Access control lists (ACLs) — provide IP Layer 3 filtering based on source/destination IP address/subnet and source/destination TCP/UDP port number
• RADIUS/TACACS+ — eases switch management security administration by using a password authentication server
• Secure Shell — encrypts all transmitted data for secure remote CLI access over IP networks
• Secure Web management with HTTPS and SSL — encrypts all HTTP traffic, allowing secure access to the browser-based management GUI in the switch
• IEEE 802.1X and RADIUS network logins — control port-based access for authentication and accountability
• 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
• Secure FTP — allows secure file transfer to and from the switch; protects against unwanted file downloads or unauthorized copying of a switch configuration file
• Switch management logon security — can require either RADIUS or TACACS+ authentication for secure switch CLI logon
• Secure management access — securely encrypts all access methods (CLI, GUI, or MIB) through SSHv2, SSL, and/or SNMPv3
• Custom banner — displays security policy when users log in to the switch
• Automatic VLAN assignment — automatically assigns users to the appropriate VLAN based on their identity and location and the time of day
• Management password — provides security so that only authorized access to the Web browser interface is allowed

Convergence

• LLDP-MED (Media Endpoint Discovery) — is a standard extension of LLDP that stores values for parameters such as QoS and VLAN to automatically configure network devices such as IP phones
• IEEE 802.1AB Link Layer Discovery Protocol (LLDP) — is an automated device discovery protocol that provides easy mapping of network management applications
• Automated voice VLAN assignment — recognizes IP phones and automatically assigns voice traffic to a dedicated VLAN for IP phones
