Secure
The Cisco Catalyst Express 500 Series Switches offer you layers of security to protect your
business. To secure the device, management traffic to and from the GUI Device Manager can be
encrypted with SSL and Simple Network Management Protocol Version 3 (SNMPv3). For network
security, you can choose from three business-optimized security levels. Tight integration with
Cisco Aironet
®
wireless access points allows you to quickly and easily deploy a secure WLAN
network. With the NAC Appliance solution, the Cisco Catalyst Express 500 Series helps protect
your network against worms and viruses and raises the overall security protection of your network
to the next level.
Easy Monitoring and Troubleshooting
Troubleshooting is easy with the Cisco Troubleshooting Advisor, which identifies cabling problems
such as wiring opens and shorts, common configuration errors, and other potential problems in
your network and recommends corrective action. Graphical trend charts and an alert LED help you
identify problems before they cause network outages.
