Layer 2 Switching |
MAC Table | Up to 8K MAC addresses |
Spanning Tree Protocol (STP) | Standard 802.1d Spanning Tree support, enabled by default Fast convergence using 802.1w (Rapid Spanning Tree [RSTP]) Multiple Spanning Tree instances using 802.1s (MSTP) 16 instances are supported |
Port Grouping | Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP) ● Up to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad link aggregation Load balance based on source and destination MAC address, or source and destination MAC/IP |
VLAN | Support for up to 256 VLANs simultaneously Port-based and 802.1Q tag-based VLANs Management VLAN 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 |
IEEE 802.1x (Authenticator Role) | 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 |
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) |
