This page lists switch IOS feature sets, versions, and a list of switch IOS features included in CCNP. The tables show an X when a particular feature is supported in a particular version and feature set. The information is these tables are based on the Cisco Feature Navigator tool (www.cisco.com/go/fn). Also, this page does not attempt to list cases where a feature may be supported at a particular version/feature set on one model router, but not on another.
This information is provided as a free services to the Cisco certification community. Please help by letting us know about any incorrect information listed in this or related pages. If you find information that is not accurate, please let us know at labdata@certskills.com. Please note that we may not be able to reply to each email individually, but will we strive to keep the data accurate.
Why Some Features, but not All?
The following tables list topics on the CCNP exams as implemented on LAN switches. The tables then show an X if the feature is believed to be supported in the particular version and feature set. The purpose of the tables is to see important differences between one feature set and another, specifically when used to practice for CCNP. As a result, the tables do not list every CCNP feature, but rather lists those most likely to be supported in one version/feature set but not another.
Switch Models and Software Feature Support
When this page last went through a major revision, the most reasonable used switches to use for a CCNP lab were 2950 and 3550 switches. Cisco switches vary much more than Cisco routers in regard to what features the software supports on a give model of switch. As a result, the following tables specifically show features checked versus 2950’s (feature sets 1 and 2) and 3550s.

Known items that need research or verification
- Cisco feature navigator does not list “voice VLAN” or similar for either 2960 or 3550. However, 3550 IOS doc confirms that the switchport voice vlan command is supported as of 12.1(9)EA1. Need to test to confirm. (labdata@certskills.com).
