Syslog Message Limits
If you enabled syslog message traps to be sent to an SNMP network management station by using the
snmp-server enable trap global configuration command, you can change the level of messages sent and
stored in the switch history table. You also can change the number of messages that are stored in the history
table.
Messages are stored in the history table because SNMP traps are not guaranteed to reach their destination. By
default, one message of the level warning and numerically lower levels are stored in the history table even
if syslog traps are not enabled.
When the history table is full (it contains the maximum number of message entries specified with the logging
history size global configuration command), the oldest message entry is deleted from the table to allow the
new message entry to be stored.
The history table lists the level keywords and severity level. For SNMP usage, the severity level values increase
by 1. For example, emergencies equal 1, not 0, and critical equals 3, not 2.
