The Global Parameters page allows you change parameters which affect the global operation of MIB Master
To change any of the parameters on this page, simply enter the new value into the appropiate field and press the "Accept" button. The new values will be installed and a new page will be displayed confirming that the new values have been added. At this point, use the "Back" button on your browser to return to the Global Parameters page.
The Log Level parameter sets the threshold for system messages generated by MIB Master. Under Windows/NT, system messages are written to the Event Log. Under Linux, they are written to /var/adm in various files. The default value is 2.
The Log Level parameter can be set a value between 0 and 3 inclusive. More messages are generated for higher values, and higher values include all messages generated by lower values
The types of messages included at each level are as follows:
0 Fatal errors only
1 All Errors
2 Warnings
3 All messages
NOTE: A Log Level value of 3 is normally used only for debugging. Using this value will substatially reduce the performance of MIB Master, and will generate a large volume of messages which may cause problems on some machines.
The SNMP Timeout parameters sets the maximum period of time that MIB Master will wait to fullfill a SNMP get or set request. The default value of 5 seconds may have to be increased for congested networks, or if SNMP communication is attempted with busy hosts that take a long time to respond.
The SNMP Retries parameter represents the maximum number of times MIB Master will resend a SNMP packets. The default value of 5 retries may have to be increased for congested networks.
The HTTP Port parameter sets the port which MIB Master uses for it's programming interface. The default value is 1090.
NOTE - immediately after submitting a page which has a new value for the HTTP Port parameter, the Web browser being used will report that it is unable to connect to MIB Master. This is normal, and is caused by the fact that the HTTP port which was formally being used no longer exists. When this occurs, the port parameter in the URL being used by the browser must be changed to reflect the new port number.
The Username and Password fields allow you to control access to the MIB Master SNMP data pages. Without this username and password, a user will only be able to access the MIB Master Home Page, and the Online Help pages. With this username and password, they will be able to access all functions except:
To have access to these functions, a user must use the Admin Username and Password
The Admin Username and Password fields allow you specify a username and password which allows access to all of MIB Master's functions. This includes the SNMP Set function, the MIB Master configuration screens and the trap display screens.
NOTE: - When using the Netscape Navigator browser to change the MIB Master Admin username and password, it will be necessary to exit and re-run Netscape. This is because Netscape caches Basic Authentication realms and this is the only mechanism possible to flush the cache. Failure to do this will result in a "403 Forbidden" response when attempting to access the controlled screens after changing the password.
