Out-of-Band Management
Management of the system is performed using Out-Of-Band (OOB) transmission methods through either the Console
port or one of the Ethernet management ports on the SPIO. OOB management ensures that no management traffic can
be accessed or viewed by any subscriber. Management data is separated on different physical interfaces from those used
to transport user data. The following figure shows this separation.

Additionally, the system uses the local context solely for system management purposes. Contexts are described in this
document‘s Glossary, but basically they provide a way to host multiple virtual service or configuration parameter
groups in a single physical device. To ensure OOB management, users are required to create other service-specific
contexts for user data.
By using the local context as the separate management context, network operations personnel are able to utilize their
own RADIUS services for management authentication and accounting, further maintaining the separation of user and
management data.
