Web User Interface
Built-in switch configuration utility for easy browser-based device configuration (HTTP/HTTPS). Supports configuration, system dashboard, system maintenance, and monitoring
Text-Editable Config Files
Config files can be edited with a text editor and downloaded to another switch, facilitating easier mass deployment
Command line interface
Scriptable CLI; a full CLI is supported. User privilege levels 1 and 15 are supported for the CLI
Cloud Services
Support for Cisco Small Business FindIT Network Tool
SNMP
SNMP versions 1, 2c, and 3 with support for traps, and SNMP version 3 user-based security model (USM)
Remote Monitoring (RMON)
Embedded RMON software agent supports 4 RMON groups (history, statistics, alarms, and events) for enhanced traffic management, monitoring, and analysis
IPv4 and IPv6 Dual Stack
Coexistence of both protocol stacks to ease migration
Port Mirroring
Traffic on a port or VLAN can be mirrored to another port for analysis with a network analyzer or RMON probe. Up to 8 source ports can be mirrored to one destination port. Four sessions are supported.
Firmware Upgrade
● Web browser upgrade (HTTP/HTTPS) and Trivial File Transfer Protocol ( TFTP)
● Dual images for resilient firmware upgrades
DHCP (Option 12, 66, 67, 82, 129, and 150)
DHCP options facilitate tighter control from a central point (DHCP server) to obtain IP address, auto-configuration (with configuration file download), DHCP relay, and hostname
Time Synchronization
Simple Network Time Protocol (SNTP)
Login Banner
Configurable multiple banners for web as well as CLI
Other Management
HTTP/HTTPS; TFTP upgrade; DHCP client; BOOTP; cable diagnostics; ping; traceroute; syslog

ACLs
Drop or rate limit based on source and destination MAC, VLAN ID or IP address, protocol, port, differentiated services code point (DSCP)/IP precedence, TCP/UDP source and destination ports, 802.1p priority, Ethernet type, Internet Control Message Protocol (ICMP) packets, IGMP packets, TCP flag
Support up to 512 rules
Port Security
Creates the ability to lock source MAC addresses to ports; limits the number of learned MAC addresses
IEEE 802.1x (Authenticator Role)
802.1X: RADIUS authentication; guest VLAN; multiple host mode
RADIUS, TACACS+
Supports RADIUS and TACACS authentication; switch functions as a client
MAC Address Filtering
Supported
Storm Control
Broadcast, multicast, and unknown unicast
DoS Protection
DOS attack prevention
STP Bridge Protocol Data Unit (BPDU) Guard
This security mechanism protects the network from invalid configurations. A port enabled for BPDU Guard is shut down if a BPDU message is received on that port
Secure Shell (SSH) Protocol
SSH is a secure replacement for Telnet traffic. SCP also uses SSH. SSH v1 and v2 are supported
Secure Sockets Layer (SSL)
SSL support: Encrypts all HTTPS traffic, allowing highly secure access to the browser-based management GUI in the switch

Support for up to 256 VLANs simultaneously
Port-based and 802.1Q tag-based VLANs
Management VLAN
Guest VLAN

Up to 8192 MAC addresses

12 Mb
