I am in the process of replacing EOL Cisco 871 routers with 892's. I can add them in and the SNMP test passes, they get backed up by NCM and I can double-click on them to get real time stats. The problem is they all show and overall hardware status of "Could not Poll". If I click on poll now it's sucessful. I've tried deleteing them and adding them back in but the status remains the same. They are running 15.x Cisco IOS which I thought might be an issue but I have Cisco 2911 routers on the same release and they work fine. Any ideas?
