The firewall's management password (also called the SNMP password) is the password needed to communicate between Network Device Command Center (NDCC) and the firewall. The logged on DeltaV user needs the CAN CONFIGURE and CAN DOWNLOAD privileges to change the firewall's management password.
The firewall's management password is not the same as an interactive accounts' passwords. The default interactive accounts are named User and Admin. Those passwords can be changed from the firewall's WebUI (HTTP) interface.
This procedure changes the firewall's management password in NDCC and the DeltaV firewall module. It does not change the management password on the actual firewall. That must be done from the firewall's WebUI (HTTP) interface.
