About Default Alarm
Settings
A new or initialized stack has four alarms defined for each port:
■
Broadcast bandwidth used
■
Percentage of errors over one minute
The default values and actions for each of these alarms are given in
Table 7-3.
About the Audit Log
The stack keeps an audit log of all management user sessions,
providing a record of changes to any MIB including the RMON MIB.
The log can only be read by users at the
security
access level using an
SNMP Network Manager.
Each entry in the log contains information in the following order:
■
Entry number
■
Timestamp
■
User ID
■
Item ID (including qualifier)
■
New value of item
There is a limit of 16 records on the number of changes stored. The oldest
records are overwritten first.
