Configuration Control

Some iMcV-Modules offer configuration control; labels on the front faceplate are identified as such. Configuration control has been implemented to assist the end user by retaining the latest configuration regardless of how that configuration was implemented (via DIP Switch settings or SNMP).

Historically, SNMP would override DIP Switch settings. If changes are made to the module via iView2, the SNMP settings determine the configuration of the board and the DIP Switches had no effect. Configuration control enables the user to use iView2 or DIP Switches to modify the configuration.

With configuration control, the end user has three conditions under which the configuration of the iMcV-Module with Configuration Control may be impacted:

•Installing an IE-iMcV-T1/E1/J1-LineTerm, TP/SFP into a chassis already loaded with iMcV-Modules or replacing an IE-iMcV-T1/E1/J1-LineTerm, TP/SFP

-The iMcV-Module will transfer its saved configurations. The IE-iMcV-T1/E1/J1-LineTerm, TP/SFP will not override the module’s configuration.

•Replacing the same type of iMcV-Module

-If the DIP Switch settings are the same as the settings on the removed iMcV- Module, the IE-iMcV-T1/E1/J1-LineTerm, TP/SFP determines the configuration settings through the chassis's management.

-If the DSW are different, then the configuration of the module is determined by the DIP Switch settings. (The settings are forwarded to the chassis's management module and the value is saved.)

•Installing a new model of iMcV-Module

-If another type of module is installed into the same slot in a chassis, the IE- iMcV-T1/E1/J1-LineTerm, TP/SFP clears the memory of the previous configuration for that slot; the settings of a new module are adopted and stored in the IE-iMcV-T1/E1/J1-LineTerm, TP/SFP.

The SNMP Write Lock switch does not impact any iMcV-Module or IE-iMcV-Module with Configuration Control. Removing and installing a new SNMP Management Module will no longer impact these modules either. However, if there is a mixture of iMcV-Modules with and without Configuration Control, the Write Lock Switch and a new SNMP Management Module must be taken into consideration.

If the command cleandb is applied to an SNMP Management Module, all the settings for the modules will be removed, but the Configuration Control modules will still be based on the last change made, while those without Configuration Control will be set to their default settings.
