6.4. Logical Networks and Permissions

6.4.1. Managing System Permissions for a Network

As the SuperUser, the system administrator manages all aspects of the Administration Portal. More specific administrative roles can be assigned to other users. These restricted administrator roles are useful for granting a user administrative privileges that limit them to a specific resource. For example, a DataCenterAdmin role has administrator privileges only for the assigned data center with the exception of the storage for that data center, and a ClusterAdmin has administrator privileges only for the assigned cluster.
A network administrator is a system administration role that can be applied for a specific network, or for all networks on a data center, cluster, host, virtual machine, or template. A network user can perform limited administration roles, such as viewing and attaching networks on a specific virtual machine or template. You can use the Configure button in the header bar to assign a network administrator for all networks in the environment.
The network administrator role permits the following actions:
  • Create, edit and remove networks.
  • Edit the configuration of the network, including configuring port mirroring.
  • Attach and detach networks from resources including clusters and virtual machines.
The user who creates a network is automatically assigned NetworkAdmin permissions on the created network. You can also change the administrator of a network by removing the existing administrator and adding the new administrator.
