Guest VLAN

Auto Voice VLAN

Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS

QinQ VLAN

VLANs transparently cross a service provider network while isolating traffic among customers

Security

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

02.1X: RADIUS authentication; guest VLAN; multiple host mode

RADIUS, TACACS+

Supports RADIUS and TACACS authentication; switch functions as a client

MAC Address Filtering

Supported

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

Management

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
