7.2 Provisioning Strategy
7.2.1 Main Concepts (Profiles, Triple Play Form, DHCP Discovery)
For managing a network, the AlliedView NMS product provides a powerful client that presents the network and its devices
in a user-friendly way, allowing its users to learn quickly how the network is configured, how to reconfigure elements when
necessary, and how to spot problems (or potential problems) before they degrade network performance.
The Allied Telesis iMG/RG is a product that supports multiple services, and when connected to the AlliedView NMS they
can be discovered and monitored, as well as provisioned; using the AlliedView NMS, the network administrator can config-
ure the RG and ensure that the correct (i.e. the most current) software loads are on the RG. This makes administration of the
(many) RGs easier to maintain.
The network administrator can follow various provisioning strategies, but all involve the following concepts:
• Profiles - A set of profiles is created that provides a set of templates that, when applied, ensure the RG is provisioned for
a specific service type with the correct attributes. There are two main profile types:
• General - These are always associated with an RG regardless of the services offered.
• Service specific - These are associated with an RG only when a specific service is to be configured.
• Triple-Play form - This form, used in previous releases to streamline provisioning of the iMAP port types, is extended to
include RG attributes. In most cases the attributes that appear and are data filled are driven by the profiles that are
included with the form.
• DHCP Discovery - Ensuring the iMG/RG is configured with the correct software and IP address is done as part of the
DHCP messaging that takes place between the iMG/RG, DHCP server, and the AlliedView NMS with its tftp server. The
series of events during DHCP ensures that the RG is correctly configured and the AlliedView NMS has created an icon
of the RG that shows where it is connected to an iMAP system.
7.2.2 Deployment Models (Access Islands, Open Access, multi-service VLANs)
7.2.2.1 Access Islands
Since a large deployment of RGs can involve many business customers and residential subscribers, there is a network hierar-
chy model that, when used and labeled correctly, can help network administrators set up and track the high number (up to
many thousand) of RGs. Refer to the following figure.
