is saved in flash memory only if these conditions are met:
The RowStatus variable (e.g., vacmAccessRowStatus) is equal to active(1).
The StorageType variable (e.g., vacmAccessStorageType) is equal to nonVolatile(3).
SNMP Configuration via a Configuration File
You can modify the SNMP configuration of the Mediatrix 4100 by inserting an SNMP Agent section in a
configuration file and then transferring this configuration file into the unit. This configuration replaces any
configuration set in a profile. For more information on how to use a configuration file for updating the Mediatrix
4100, see “Chapter 7 -
Configuration File Download” on page 99.
The SNMP Agent section is located in the SnmpGenericTemplate.xml file located under Unit Manager
Network 3.2\UnitManager\DefaultCfgFile folder. The contents of the SnmpGenericTemplate.xml file may be
appended at the end of the generated XML file. See the Unit Manager Network documentation for more
details.
The SNMP agent section must not be separated by other comments or OIDs in the configuration file.
If you transfer a configuration file with an SNMP Agent section that constitutes a change from the SNMPv3
configuration currently in use, the new configuration is applied and the unit then restarts so that the changes
take effect.
A few notes:
Once an SNMPv3 configuration is in effect in the Mediatrix 4100, it is not possible to revert the
unit back to SNMPv1 or SNMPv2c by sending it a configuration file that does not include an
SNMP Agent configuration section.
If you perform a factory reset, all settings previously applied via the configuration file (including
the SNMPv3 configuration) are lost and the unit reinitializes by using the current profile.

Caution: The SNMP Agent section contains the default Media5 parameters related to SNMP. Default
values enable SNMPv1, SNMPv2, and SNMPv3 and provide default Media5 credentials for SNMPv3.
