  • Integrated security, including network admission control (NAC)
  • Enhanced quality of service (QoS)
  • Resiliency to deliver intelligent services for the network edge
  • 48 10/100/1000 PoE ports and 4 Small Form-Factor Pluggable (SFP) uplinks
  • High-speed stacking for up to nine switches
  • Unified stack management to simplify management of the network access layer
  • Auto software image and configuration provisioning for plug-and-play hardware replacement
  • Network control and bandwidth optimization using QoS shaping, granular rate limiting, traffic classification, sophisticated access control lists (ACLs), and multicast services
  • NAC through a wide range of authentication methods and support for the Cisco Catalyst Integrated Security Framework
  • Common Cisco IOS Software with support for Auto QoS and Smartports
  • Easy network configuration and troubleshooting using Cisco Network Assistant software
  • Software updates at no additional charge

90 minutes of FREE Cisco switch training on video

A friend of mine recently pointed me to these FREE videos that go in depth on how to configure Cisco switches and configure VLANs. There are 6 parts to these videos and, together, they are over 1.5 hours long (90 minutes). Cisco CCIE, Chris Bryant is the instructor and he does a great job showing you, on a Cisco switch, how to configure all that you need to know - both to administer a Cisco switch and to prepare for the Cisco CCNA certification or the CCNP switching exam. I hope you will take a look at these free Cisco switching videos.
