Технические характеристики:

Feature	Description
Performance
DRAM/flash memory	32MB DRAM 16MB flash memory

Layer 2 Switching
Spanning Tree Protocol	Fast convergence using 802.1w, enabled by default Portfast: supported on: "Desktop," "Phone + Desktop," "Printer," and "Server" Smartports roles
MAC addresses	8000 MAC addresses
Virtual LANs (VLANs)	Up to 32 VLANs (1000 range) and support for 802.1Q trunking using Cisco Smartports
Number and type of queues	4 queues per port • Shaped Round Robin (SRR) queuing • Support for DSCP and CoS using Cisco Smartports
Port grouping	Support for Cisco EtherChannel® and IEEE 802.3ad • Up to 6 groups • Up to 8 ports per group
Smartports (Preset Cisco Recommended Network Enhancements, QoS, and Security)
Desktop	• Optimized for desktop connectivity • Configurable VLAN setting • Port security enabled to limit unauthorized access to the network
IP Phone + Desktop	• Optimized QoS for IP Phone + Desktop configurations • Voice traffic is placed on "Cisco-Voice" VLAN • Configurable data VLAN • QoS level assures Voice-over-IP (VoIP) traffic takes precedence • Port security enabled to limit unauthorized access to the network
Router	• Configured for optimal connection to a router or firewall for WAN connectivity
Switch	• Configured as an uplink port to a backbone switch for fast convergence • Enables 802.1Q trunking
Access Point	• Configured for optimal connection to a wireless access point • Configurable VLAN
Server	Can be classified as trusted, critical, business, or standard server: • Trusted: for use with Cisco CallManager Express, same QoS setting as Voice (VoIP traffic is prioritized) • Critical: for critical servers with QoS set higher than default • Business: default setting; QoS higher than desktop Internet traffic • Standard: for servers set to same level as regular desktop Internet traffic Configurable VLAN Port security enabled to limit unauthorized access to the network
Printer	• QoS settings for "Printer" are the same as "Desktop," "Access Point," and "Standard Server" • Configurable VLAN • Port security enabled to limit unauthorized access to the network
Guest	• Guests are allowed access to the Internet, but not to the company network • All guest ports are placed on the "Cisco-Guest" VLAN • Port security enabled to limit unauthorized access to the network
Other	• "Other" Smartports role allows for flexible connectivity of nonspecified devices • Configurable VLAN • No security • No QoS policy
Diagnostic	Customers can connect diagnostics devices to monitor traffic on other switches (configurable using Cisco Network Assistant only)
Security
SSL	SSL support: encrypts all HTTP traffic, allowing secure access to the browser-based management GUI in the switch
Security policy slider	Three security levels: low, medium, and high (configurable using Cisco Network Assistant only): • Low: for business environments where there is limited guest access; limited number of devices are allowed per port • Medium: for business environments where security is important; only authorized devices (by MAC address) are allowed on the company network • High: for business environments where security is critical; only authorized devices (by MAC address) and authenticated users (using IEEE 802.1x) are allowed on the company network
Multicast	• High-bandwidth video traffic is optimized so that it does not affect other applications on the network. • Internet Group Management Protocol (IGMP) (v1, v2, and v3) snooping: IGMP snooping constrains multicast traffic at Layer 2 by configuring Layer 2 LAN ports dynamically to forward multicast traffic only to those ports that want to receive it.
