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:
Network level out-of-band servers allow you to set up access to out-of-band servers that are used by specific networks only.
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.
