Zarządzanie, monitorowanie, konfiguracja

Dual flash images — provides independent primary and secondary operating system files for backup while upgrading
Find-Fix-and-Inform — finds and fixes common network problems automatically
Friendly port names — allows assignment of descriptive names to ports
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
Multiple configuration files — allows multiple configuration files to be stored to a flash image
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
Virtual stacking — provides single IP address management for up to 16 switches
alarms
and events
history
sFlow (RFC 3176) — delivers wire-speed traffic accounting and monitoring configured by SNMP and CLI with three terminal encrypted receivers
then informs the administrator

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)
Custom banner — displays security policy when users log in to the switch
GUI
MAC address lockout — prevents particular configured MAC addresses from connecting to the network
Port security — allows access only to specified MAC addresses
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 resourc
RADIUS/TACACS+ — eases switch management security administration by using a password authentication server 
STP BPDU port protection — blocks Bridge Protocol Data Units (BPDUs) on ports that do not require BPDUs
STP root guard — protects the root bridge from malicious attacks or configuration mistakes
Secure FTP — allows secure file transfer to and from the switch, protects against unwanted file downloads or unauthorized copying of a switch configuration file
Secure Sockets Layer (SSL) — encrypts all HTTP traffic
Secure management access — delivers secure encryption of all access methods (CLI
Secure shell — encrypts all transmitted data for secure remote CLI access over IP networks
Secure shell (SSHv2, client and server) — encrypts all transmitted data for secure remote CLI access over IP networks
Source-port filtering — allows only specified ports to communicate with each other
allowing secure access to the browser-based management GUI in the switch 
or MIB) through SSHv2 and SNMPv3 
preventing forged BPDU attacks
which can be learned or specified by the administrator

QoS

    - 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
Flow control — helps deliver reliable communication during full-duplex operation
IP Type of Service (ToS)
Layer 3 protocol
Layer 4 prioritization — enables prioritization based on TCP/UDP port numbers
Rate limiting — sets per-port ingress enforced maximums for all ingressed traffic or for broadcast
Simplified QoS configuration
TCP/UDP port number
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)
and DiffServ
multicast
or unknown destination traffic
source port

Funkcje L2

16K MAC address table — provides access to many Layer 2 devices 
094 VLAN IDs
GARP VLAN Registration Protocol — allows automatic learning and dynamic assignment of VLANs
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
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
VLANs — provides support for 512 VLANs and 4
