Interface Configuration Guide

3.1 Configuration Overview
This guide uses the term “preprovisioning” in the context of preparing or
preconfiguring entities such as chassis slots, the IOM, adapter cards, ports, and
interfaces, prior to hardware actually being installed in the chassis. These entities
can be installed but not enabled. When the entity is in a no shutdown state
(administratively enabled), the entity is considered to be provisioned.
Nokia 7705 SAR routers provide the capability to configure chassis slots to accept
specific adapter card types and set the relevant configurations before the equipment
is actually installed. The preprovisioning ability allows you to plan your configurations
as well as monitor and manage your router hardware inventory. Ports and interfaces
can also be preprovisioned. When the functionality is needed, the cards can be
inserted into the appropriate chassis slots as required.
The following sections are discussed:
• Configuring the IOM and Card Slot
• Configuring Adapter Cards and Modules
• Configuring Ports
• Configuring SCADA Bridges
3.1.1 Configuring the IOM and Card Slot
The 7705 SAR card slot ID is always 1 and the card type for the IOM is always
iom-sar.
On the 7705 SAR-8 and 7705 SAR-18, the CSM, which can only be installed in slot
A or B of the chassis, does not need to be provisioned. However, the IOM, which is
virtualized in the 7705 SAR software, must be activated before the adapter cards,
ports, and SCADA bridges can be preprovisioned and configured. The IOM is
activated by designating it a card slot ID and card type. This enables the chassis slots
to accept the adapter cards.
Note: On the 7705 SAR-8, the CSM is called the CSMv2; both terms are used
interchangeably in these guides. The CSMv2 supports bandwidth of 10 Gb/s, 2.5 Gb/s and
1 Gb/s in the first two adapter card slots and 2.5 Gb/s and 1 Gb/s in the remaining four
adapter card slots. Support for 2.5 Gb/s and 10 Gb/s adapter cards by the CSMv2 is only
available on the 7705 SAR-8 Shelf V2.
