Configuration Overview
NOTE: This document uses the term preprovisioning in the context of preparing or preconfiguring
entities such as chassis slots, line cards (or Control Forwarding Module (CFM/IOM) cards), MDA
carrier modules (MCMs), media dependent adapters (MDAs), compact media adapters (CMAs),
ports, and interfaces, prior to initialization. These entities can be installed but not enabled. When
the entity is in a no shutdown state (administratively enabled), then the entity is considered to be
provisioned.
Alcatel-Lucent 7710 SR routers provide the capability to configure chassis slots to accept specific
line card and MDA 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 card(s) can be inserted into the appropriate chassis slots
when required.
The following sections are discussed.
• Chassis Slots and Cards on page 18
• MDAs on page 18
• MCMs on page 20
• CMAs on page 22
• Ports on page 27
Chassis Slots and Cards
To pre-provision a chassis slot, the line card type must be specified as well as the MDA/CMA
type. System administrators or network operators can enter card type information for each slot,
allowing a range of card types in particular slots. From the range of card types, a card and
accompanying MDAs/CMAs are specified. When a card is installed in a slot and enabled, the
system verifies that the installed card type matches the allowed card type. If the parameters do not
match, the card remains offline. A preprovisioned slot can remain empty without conflicting with
populated slots.
Configuration Overview
Page 20 7710 SR OS Interface Configuration Guide
MCMs
An MCM (MDA Carrier Module) slot must be configured before an MDA (Media Dependant
Adapter) can be provisioned. If you provision an MDA type before an MCM slot is configured, it
is assumed you are provisioning a Compact Media Adapter (subscriber/SAP/spoke SDP). CMAs
do not require MCM pre-configuration. Up to two MCMs may be provisioned on a on a 7710 SR-
c4. Even numbered slots are invalid for MCM installation (MCMs physically span 2 slots; “mcm
1” spans slots 1 and 2)
Refer to the CMA Installation Guide(s) and MDA Installation Guide(s) for more information on
the physical characteristics of each card.
MDAs
A chassis slot and card type must be specified and provisioned before an MDA can be
preprovisioned. An MDA is provisioned when a type designated from the allowed MDA types is
inserted. A preprovisioned MDA slot can remain empty without conflicting with populated slots.
Once installed and enabled, the system verifies that the installed MDA type matches the
configured parameters. If the parameters do not match, the MDA remains offline.
A chassis slot, card type and MCM must be specified and provisioned before an MDA can be
preprovisioned. An MDA is provisioned when a type designated from the allowed MDA type is
inserted. A preprovisioned MDA slot can remain empty without conflicting with populated slots.
Up to two MDAs may be provisioned on a on a 7710 SR-c4. Even numbered slots are invalid for
MDA installation (MDAs physically span 2 slots; “mda 1” spans slots 1 and 2).
MDA output displays an “m” in the name of the card. The following displays a
show card state
command. In this example, an m60-10/100eth-tx MDA is installed in slot 1.
