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 
Inline power (PoE) 
● 
All 24 PoE ports on the Cisco Catalyst Express 500-24PC can supply up to 15.4W 
(IEEE 802.3af standard maximum) of power over Category 5 cable, for a total of 370W 
of inline power. 
● 
All 4 PoE ports on Cisco Catalyst Express 500-24LC switches can supply up to 15.4W 
of power over Category 5 cable, for a total of 62W of inline power. 
● 
Both the IEEE 802.3af PoE standard and Cisco prestandard inline power are supported.
