Configuring Logging

Enter the email addresses of the people who should receive the exception
reports in the same way that you entered addresses for emailed logs.
5. Specify the priority level for events that the router forwards to the email
addresses:
Syntax: logging email priority-level [info | notice | warning | error | fatal]
For example:
ProCurve(config)# log forwarding priority-level error
The priority level can be the same as or different than that for events
logged to the router's event history. The default level is warning.
6. You can also specify what will appear in the From field of the email
message by entering:
Syntax: logging email sender <source>
The message will simply consist of logs without any explanation, so the
From field must give recipients enough information to know which device
originated the logs. For example, enter:
ProCurve(config)# logging email sender admin@procurve.com
7. As with forwarded logs, you can force the router to send all emailed logs
(and exception reports) with the same source address. This source
address is taken from the interface that you specify with this command:
Syntax: logging email source-interface <interface ID>
