Network Management Overview A-3 Table A-1 Managed and Unmanaged Devices Managed Devices Are auto-discovered for topological display. Automatically attaches and deletes. Supports monitoring and control of device and port status. Unmanaged Devices Are added manually for topological display. Cannot be managed via HMU currently. Can only be manually attached and deleted. Proxy Master The proxy master is a managed device that connects the two sections of the managed network - the Ethernet part with the Fibre Channel part. The proxy master accomplishes the following tasks: The proxy master relays the communications from the Hub 12 Management Utilities to the individual devices on the Fibre Channel network. To do this, the proxy master must have an Ethernet connection. However, the proxy master communication can not occur through an Ethernet connection alone. The proxy master turns on numerous management features within the system (once it is properly configured internally). One of the most important management features is the MIB, the repository of information about the current status of the entire network. The proxy master automatically polls other managed devices to determine their current status. The proxy master relays commands issued by the network administrator. The Compaq Storage Hub 1 Fibre Channel Hub with the Hub 12 Management Module installed is the device that acts as the proxy master. When properly configured, it routinely collects data from all the slave-managed devices connected to it by Fibre Channel by using the Compaq Inter-Hub Communication Interface (ICI). The ICI runs over the Fibre Channel cables but uses its own logical channel not used by the standard protocol (out-of-band communications) without affecting the overall performance of the system.

Proxy Master
The proxy master is a managed device that connects the two sections of the
managed network – the Ethernet part with the Fibre Channel part. The proxy
master accomplishes the following tasks:
±
The proxy master relays the communications from the Hub 12
Management Utilities to the individual devices on the Fibre Channel
network. To do this, the proxy master must have an Ethernet connection.
However, the proxy master communication can not occur through an
Ethernet connection alone.
±
The proxy master turns on numerous management features within the
system (once it is properly configured internally). One of the most
important management features is the MIB, the repository of
information about the current status of the entire network. The proxy
master automatically polls other managed devices to determine their
current status.
±
The proxy master relays commands issued by the network administrator.
The Compaq Storage Hub 1 Fibre Channel Hub with the Hub 12 Management
Module installed is the device that acts as the proxy master. When properly
configured, it routinely collects data from all the slave-managed devices
connected to it by Fibre Channel by using the Compaq Inter-Hub
Communication Interface (ICI). The ICI runs over the Fibre Channel cables
but uses its own logical channel not used by the standard protocol (out-of-band
