CCNA Router IOS Features

This page lists:

  • Sections by IOS Version
  • Each section lists Features Sets researched at that IOS version
  • Each section lists two tables, one for the ICND1 exam features, and one of the ICND2 exam features
  • Each table lists rows with IOS features important to the exam
  • Each table’s columns lists an X when a given feature set supports a given feature

These tables use the Cisco Feature Navigator tool (www.cisco.com/go/cfn) as the basis for the information in the table. Note that the information varies from router, so this page shows data collected for a given model plus version plus feature set.

The tables on this page do not list all CCNA features. Instead, it lists a subset of CCNA features so that you can see differences between IOS versions, feature sets, and router models.

  1 Cisco Feature Navigator shows this feature as not supported, but with other similar features supported, it could be that Cisco Feature Navigator is simply incorrect.

 1 I am suspicious whether feature navigator is correct, that a 2610XM with this version and feature set does not have EIGRPv6 support. If you have that combination to test, please let me know, labdata@certskills.com.
