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



  •          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


  •          Optional 10 Gigabit Ethernet ports — allow the addition of 10 Gigabit Ethernet connections for uplinks or high-bandwidth server connections; flexibly supports XFP, SFP+, or CX4 local connections
  •          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


  •          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
  •          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
  •          IEEE 802.1AB Link Layer Discovery Protocol (LLDP) — automated device discovery protocol provides easy mapping using network management applications
  •          sFlow (RFC 3176) — wire-speed traffic accounting and monitoring
  •          Advanced IRF technology stacking — locally connects up to four 4210G switches using 10 Gigabit Ethernet or CX4 local connections; improves resiliency by spreading aggregated links across multiple stacked units; provides simplified management with single IP management and a unified control interface per stack

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 Layer 3 routing



  •          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
  •          Secure FTP — allows secure file transfer to and from the switch; protects against unwanted file downloads or unauthorized copying of a switch configuration file
  •          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
  •          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
  •          STP BPDU port protection — blocks Bridge Protocol Data Units (BPDUs) on ports that do not require BPDUs, preventing forged BPDU attacks
  •          Dynamic IP lockdown — works with DHCP protection to block traffic from unauthorized hosts, preventing IP source address spoofing
  •          DHCP protection — blocks DHCP packets from unauthorized DHCP servers, preventing denial-of-service attacks
  •          Dynamic ARP protection — blocks ARP broadcasts from unauthorized hosts, preventing eavesdropping or theft of network data
  •          STP Root Guard — protects the root bridge from malicious attack or configuration mistakes


  •          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


  •          Lifetime warranty — for as long as you own the product with advance replacement and next-business-day delivery (available in most countries)*
