About the Audit Log

The Switch 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 fol-
lowing 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.
