RMON and the Switch 61 Table 6 Values for the default alarm(s) Statistic High Threshold Number of errors Value: 8 errors per 10 over 10 seconds seconds Action: Smart auto-sensing will reduce port speed Low Threshold Recovery Period Value: 8 errors per 10 seconds 10 secs Action: None. (Speed can only be increased upon link loss, for example by removing and replacing the cable, or by triggering the port to perform another auto-negotiation on that link.) 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 The last 16 operations are stored in the audit log. The oldest records are overwritten first. Email Notification of Your Switch allows you to receive email notification when certain RMON Events events occur. You can receive notification via email, SMS (Short Message Service), or pager, of the event that has occurred. This feature uses an SMTP (Simple Mail Transfer Protocol) email client to send the notification email. The Short Message Service (SMS) and pager messages are constrained on message size so they are sent to a different email address which creates the message to be displayed and then forwards it on to the SMS or pager gateway.
