What numeric code indicates an error condition message in Cisco IOS router logs?

In Cisco IOS router logs, the numeric code that indicates an error condition message is 3. This is part of Cisco's logging system, where different severity levels are assigned to various types of messages to help network administrators quickly assess the importance of an event.

Severity level 3 corresponds to "error" messages. These messages indicate a problem that requires attention but may not be critical to the operation of the router. They signify that something is wrong that could potentially disrupt services. It's essential for network administrators to monitor these messages to maintain network health.

Other severity levels, such as 1 (emergency), 2 (alert), and 4 (warning), denote different types of issues, with levels 1 and 2 indicating more serious conditions than level 3, while level 4 represents conditions that are less severe and may not require immediate attention. Understanding these severity classifications helps in prioritizing response actions efficiently.
