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.
Product Specifications
