How do I configure a Customizable Group so that it includes only those devices actually configured with backup interfaces?
1. Edit a Customizable Group, adding only those devices that have backup interfaces configured on them. 2. Set Membership Update for the customizable group to Upon user request only. As a result, ITM will not update the membership of the group as devices are added and deleted from ITM inventory. To maintain this group, edit it after you add or remove devices with backup interfaces to ITM.
