Configuration overview
This guide uses the term ‟preprovisioning” in the context of preparing or preconfiguring entities such as chassis slots, line cards (for example, Switch Fabric and Control Plane Module (SF/CPM) and Integrated Media Modules (IMMs)), and media dependent adapters (MDAs), ports, and interfaces, before initialization. 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.
The 7210 SAS-T, 7210 SAS-Mxp, 7210 SAS-Sx/S 1/10GE, and 7210 SAS-Sx 10/100GE and its variants, are platforms with a fixed port configuration, and no expansion slots. 7210 SAS software inherits the concept of CPM, IOM, and MDA from the SR OS to represent the hardware logically. These logical cards are fixed and are not removable. The software creates two (2) logical cards to represent the CPM and IOM; the cards are preprovisioned on bootup. The IOM card is modeled with a single MDA that is a logical entity and represents the fixed ports on the system. The MDA is auto-provisioned on bootup and does not need to be provisioned. Ports and interfaces can also be preprovisioned.
The 7210 SAS-R6 is a chassis-based platforms that has 6 IMM slots that can accept media cards used for service delivery and 2 CPM slots that provide control-plane redundancy. The chassis slots must be provisioned to accept a specific line card 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 when required.
The 7210 SAS-R12 is a chassis-based platforms that have 12 IMM slots that can accept media cards used for service delivery and 2 CPM slots that provide control-plane redundancy. The chassis slots must be provisioned to accept a specific line card 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 when required.
Chassis slots and cards
The 7210 SAS-T, 7210 SAS-Mxp, 7210 SAS-Sx/S 1/10GE, and 7210 SAS-Sx 10/100GE are platforms which have a set of fixed ports. Software preprovisions the cards on bootup. No expansion slots are supported on these platforms.
The show card command lists the cards auto-provisioned on 7210 SAS-T, 7210 SAS-Mxp, and 7210 SAS-Sx/S 1/10GE chassis.
The following show card sample output lists the cards auto-provisioned on 7210 SAS-T chassis.

The 7210 SAS-R6 is a chassis based platform with 6 IMM slots and 2 CPM slots. On a chassis based platform the slots must be provisioned. To preprovision a chassis slot, the line card type must be specified. 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 (if any) 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. 7210 SAS-R6 supports only CPM and IMMs. It does not support any physical removable MDAs. Software uses logical MDAs internally to represent the ports on the IMMs and the MDA type is auto-provisioned by software when the IMMs are provisioned. Check the latest release notes for a list of supported card types (that is, CPM and IMMs). See the 7210 SAS-R6 Chassis Installation Guide for more information about installation of cards.
The 7210 SAS-R12 is a chassis based platform with 12 IMM slots and 2 CPM slots. On a chassis based platform the slots must be provisioned.

Please check the latest release notes for a list of supported card types (that is, CPM and IMMs). See 7210 SAS-R12 Chassis Installation Guide for more information about installation of cards.
On the 7210 SAS-R6 and 7210 SAS-R12, the user must preconfigure the type of IMMs that will be populated so that appropriate resources can be allocated on system bootup. See the config>system>chassis>allow-imm-family command in the 7210 SAS-Mxp, R6, R12, S, Sx, T Basic System Configuration Guide for more information.
