Which command increases R1's local log buffer size and captures more messages at an informational level?

The command logging buffered 16000 informational increases the local log buffer size to 16000 bytes and sets the logging level to informational. The logging buffered command is entered in global configuration mode, as indicated by (config). The size specified (16000) is a common buffer size, and "informational" ensures that messages at this level and higher (notifications, warnings, errors, critical, alerts, emergencies) are captured. The options using critical would only capture messages at the critical level and higher, missing informational messages. The option logging buffered 4096 informational would set the correct logging level but use a smaller buffer size than requested by "captures more messages.
