Out-of-Band management of devices is a method to access a device when the primary management path is not available. Out-of-Band (OOB) Servers provide for direct console or AUX connectivity to your devices.

The servers that can be configured include, Modem Banks and Term Services. Both OOB server types support sever authentication.

Phone numbers and port information for each device is set within the device properties Communications tab.

Network Configuration Manager provides an option for setting up alternative communication methods using out-of-band servers.

For example, if there is a problem with a device and traffic cannot flow through the network, an alternate path can be set using a terminal server to reach the network nodes--even when the network is down.

Out-of-Band servers are used when you need a secure, remote, emergency network access path to manage and troubleshoot device issues when:

  • The device is not on the network

  • The device is not network manageable

  • The network is down 

Network Configuration Manager allows you to set up out-of-band servers at two levels:

  • Global level

  • Network Level 

Global level out-of-band servers allow you to set up access to out-of-band servers that can be used by any network being managed using Network Configuration Manager.


When you have configured an out-of-band server for a network, the network defaults to use the network level out-of-band server, unless otherwise indicated.
