Normally, a cisco router will check for aggressive-mode during boot or responding to an IKE request which is what it appears to be with the information you have provided. How often does this message appear? every few minutes or only at initialisation stage? it could just mean that there are some peers trying to connect via IPSEC to your router.

Have a read of the below support page, depending on your environment setup you may be able to get away with adding the host as a peer to stop the informational logs.<br />
<br />
Do you know which peers are trying to communicate over IPSec to your router?<br />

IT Administration is the processes and best practices for programming and development, and incorporates methodologies for managing activities and projects. Common methodologies include waterfall, prototyping, iterative and incremental development, spiral development, rapid application development, extreme programming and various types of agile methodology. The life-cycle "model" is a more general term for a category of methodologies, and a software development "process" a more specific term to refer to a specific process chosen by a specific organization.

IT Administration

Network Management involves issues that are independent of specific hardware or software, including email policies, upgrade planning, backup scheduling and working with managed service providers for Desktop-As-A-Service (DaaS), Software-As-A-Service (SaaS) and the like through the use of tools, coupled with manufacturer standards, best practice guidelines, policies and procedures plus all other relevant documentation. Network management also includes monitoring, alerting and reporting, management reporting, planning for device or service updates, the backup of configurations, the setting of key performance indicators and measures (KPIs/KPMs), associated service level agreements and problem records as part of the IT Service Management (ITSM) framework.

Network Management

Telecommunication occurs when the exchange of information between two or more entities (communication) includes the use of technology. Communication technology uses channels to transmit information (as electrical signals), either over a physical medium (such as signal cables), or in the form of electromagnetic waves. The word is often used in its plural form, telecommunications, because it involves many different technologies.
