My client is having an older Cisco router. It has been long since it was modified and there network engineer has left the job long back. So there is no contact with him anymore. They now want to add a new server to this router. However no one knows about its password. Is there anyway to get this? Do I need to run the setup software again? Is there any tool to get this information? I have heard about some SNMP tool which helps in this matter?
