RMON and Your Switch

The Audit Log
The Switch keeps an audit log of all management user sessions, providing
a record of a variety of changes, including ones relating to RMON. The
log can only be read by users at the
security
access level using an SNMP
Network Management application.
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.
