Opis

QoS - Traffic prioritization (IEEE 802.1p) — allows real-time traffic classification with support for eight priority levels mapped to either two or four queues; uses weighted deficit round robin (WDRR) or strict priority (SP) - Simplified QoS configuration     - Port-based — prioritizes traffic by specifying a port and priority level     - VLAN-based — prioritizes 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 Bezpieczeństwo - Access control lists (ACLs) — accommodates IPv4/IPv6 port and VLAN-based ACLs (IPv6 ACL is supported only on Gigabit Ethernet and 48-port models) - 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  - Secure Sockets Layer (SSL) — encrypts all HTTP traffic, allowing secure access to the browser-based management GUI in the switch  - 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 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 — delivers secure encryption of 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 Zarządzanie, monitorowanie, konfiguracja - Virtual stacking — provides single IP address management for up to 16 switches - sFlow (RFC 3176) — delivers wire-speed traffic accounting and monitoring configured by SNMP and CLI with three terminal encrypted receivers - IEEE 802.1AB Link Layer Discovery Protocol (LLDP) — automates device discovery protocol for easy mapping by network management applications - Logging — provides local and remote logging of events via SNMP (v2c and v3) and syslog; provides log throttling and log filtering to reduce the number of log events generated - Port mirroring — allows traffic to be mirrored on any port or a network analyzer to assist with diagnostics or detecting network attacks - RMON (remote monitoring) — provides advanced monitoring and reporting capabilities for statistics, history, alarms, and events - Find-Fix-and-Inform — finds and fixes common network problems automatically, then informs the administrator - Friendly port names — allows assignment of descriptive names to ports - Dual flash images — provides independent primary and secondary operating system files for backup while upgrading - Multiple configuration files — allows multiple configuration files to be stored to a flash image Funkcje L2 - VLANs — provides 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; 8- and 24-port Fast Ethernet models automatically support up to 2000-byte frames with no configuration needed - 16K MAC address table — provides access to many Layer 2 devices  - GARP VLAN Registration Protocol — allows automatic learning and dynamic assignment of VLANs - Per-VLAN Spanning Tree Plus (PVST+) — allows each VLAN to build a separate spanning tree to improve link bandwidth usage in network environments with multiple VLANs
