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 Back to top 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 Back to top 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 Back to top 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 Back to top 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 Back to top 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 Back to top 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 Відредаговано 28 вересня, 2013 Haxxproxx!
