Looking at a port, there are buttons to 'Shutdown' or 'Turn On' the port. When I mouse-over the clickable part of these buttons, I get the message "RW credential is not defined for the node", and cannot use the buttons. I have searched the Quick Start Guide, Administrator Guide, and these forums for RW credential, but only come up with credentials related to Active Directory. These are HP and Cisco switches, which are not Active Directory integrated.
How can I specify a credential to use for these functions?
You can edit nodes and their credentials in Node management. Go to Settings, and click "Manage Nodes" in the "Node & Group Management" section. Select the nodes for which you want to add the R/W credential and click Edit Properties button. This will bring you to the page where you can set it.
