Documentation
Possibly the most important requirement in any network environment is to have current and
accurate information about the network available at all times. During the process of changing
the network, it is critical to ensure that documentation is kept up to date. Network
documentation should include the following:
Detailed physical layer drawing that displays all network devices that have a medium risk
(or higher) on the network. The drawing should include rack layouts, cable connections,
and devices.
Detailed network layer drawing of all network devices that have a medium risk (or higher)
on the network. The drawing should include addresses, and IP subnetwork and VLAN
information.
Out-of-band management access maps and documentation.
Solution templates.
Detailed numbering plans and assignments.
Detailed dial plan and call routing information.
VLAN numbering plans and assignments.
Network Region assignments.
Naming standards for all network devices.
Software code and hardware types that are currently implemented and supported.
Protocol filtering criteria and methodologies.
Routing protocols standards and supported modifications from default settings.
Global configuration standards.
Inventory database for all physical connectivity and contact information.
In addition, Avaya recommends that you develop a matrix that contains information about user
groups, the applications they require, and the servers (addresses and locations) that host these
applications. This information is necessary to ensure that users continue to have the level of
access and performance they require during and after the change. In addition, previously used
test plans assist in simplifying future changes, and they may assist in troubleshooting problems
that occur because of a change.
