I'm unable to configure Dynamic ARP Inspection on Cisco C2960X with c2960x-universalk9-mz.152-6.E2 IOS version

Hi, 

I'm not able to configure DAI on C2960x even after I upgrade the IOS to c2960x-universalk9-mz.152-6.E2,

How can I resolve this issue? 

Many thanks

Hello,

with the image installed, you need to activate either the LAN Lite or the LAN Base feature set. What is the output of 'show lic' ?

Hello, 

Thank you for your reply, 

The License installed is LAN Lite, 

How can I change it to LAN Base ?

best regards,

[Georg Pauwen]

Hello,

LAN Lite should be sufficient. 

To install the LAN Base license:

1. license right-to-use activate lanbase acceptEULA
2. reload

Hello,

If the right to use licensing is not available, you need to purchase a license and then use the license install command...
