Cisco 1921 Router features

[Brett Paulins]

I am trying to decipher the differences between the two models of the 1921 router. One has an IP Base IOS and the other has a Security IOS. I have an ASA so I don't think I need all the Security IOS bells and whistles on an internal router. Although, does the IP Base IOS allow for trunking and sub interfaces? I definitely need that and on CDW's website it says that the 1921-Sec/K9 w/ Security IOS includes 802.1Q and that spec is not listed on the 1921/K9 IP Base IOS model.

Hello Brett,

This page wiil help you: http://tools.cisco.com/ITDIT/CFN/jsp/index.jsp

I saw that IP BASE include 802.1Q but you can check there all features which you need.

Research software -> choose platform and then choose version of IOS which you have.

It is quite straightforward...

Brilliant page, I just come accross it -> https://supportforums.cisco.com/thread/2170638

With just IP Base image, I can do both Sub-interface and trunk on a 2921 running IOS 15.2.  Should be the same for 1921.
