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 iView

, the SNMP settings determine the configuration of the board and

the DIP Switches had no effect. Configuration control enables the user to use iView

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.
