I researched on this error internally and it seems that you are hitting a software defect - CSCsc64248 which is duplicate of CSCec74317

Could you please let me know if you have SNMPv3 configured on the router.

Another thing that i want to point out is your config-register is not correct. Could you please rectify it to 0x2102.

Hope this answer your query.

Hi Vinit,

Thank you so much for the help.

Yes indeed we are using V3.

Based on the defect, it has been noticed on nodes enabled with SNMPv3. I cannot say you should remove SNMPv3 as it might be a production router but i think the better option would be to upgrade the router to a fixed version.

Hope that helps.

Vinit
