5.6.1 Rules of thumb and remarks concerning management
The following lists some rules of thumb concerning the management of OneAccess devices in a network:
• Make sure there is only one path towards the management system. Else you might get unexpected
results (e.g. devices that do not answer to polling, answer of several devices at once when polling one
device, etc.).
• Once your network starts to become complex on management level (i.e. more than just in-line
connections as depicted in Section 6.5 Management configuration attributes), you are advised to use
absolute addressing instead of relative addressing.
In practice, it is best to use absolute addressing when you configure one of the attributes listed below
as follows:
− ctrlPortProtocol attribute to management.
• If you use a router interface in the Crocus CNV, then you are advised to set the ctrlPortProtocol attribute
to management. Else you might be unable to manage the router interface.
• The Crocus CNV is not a true multi-device (a multi-device is a device that incorporates several
devices on one card, such as the Crocus SHDSL CV Twin). However, if a router interface is inserted
in both modular interface slot A and B and the ctrlPortProtocol attribute is set to …
− console, then the router interface in interface slot B is linked to “modem B”. In practice, this means
that when using e.g. a management concentrator you have to specify modem B in your exit port
settings.
− management, then the router interface in interface slot B is linked to “modem A”. In practice, this
means that when using e.g. a management concentrator you have to specify modem A instead of
modem B in your exit port settings.
• Changing the ctrlPortProtocol attribute causes the Crocus CNV to reboot.
