What It Means

The chassisd database provides the date, time, and a component status message. The chassisd database is dynamic. It is initialized at router startup and is updated when components are added or removed. You can search for multiple items in the chassisd log file by using the | match "item | item | item" command. For example, | match "ssb | kernel | tnp" is a search for error messages for the SSB, kernel, and Trivial Networking Protocol (TNP), and indicates communication issues between the Routing Engine and the Packet Forwarding Engine components.
