Basic configuration

For 7210 SAS platforms that do not support any removable cards or MDAs (7210 SAS-T, 7210 SAS-Mxp, 7210 SAS-Sx/S 1/10GE, and 7210 SAS-Sx 10/100GE), the card and MDA is auto-provisioned and operators can directly start with identifying and configuring the ports as follows.

On 7210 SAS chassis-based platforms, (7210 SAS-R6 and 7210 SAS-R12), the card type must be provisioned and operators need to start from identifying the chassis slot and configuration of the slot and card type, as shown below.

The most basic configuration must have the following:

  • identify chassis slot (if applicable)

  • specify line card type (must be an allowed card type).

  • identify MDA slot (if applicable)

  • specify MDA (must be an allowed MDA type) – if applicable

  • identify specific port to configure

Configuring cards and MDAs

Card configurations include a chassis slot designation.

The following is a sample of card configuration output for the 7210 SAS-R6.

A:SASR6>config>card# info
----------------------------------------------
        card-type imm-sas-2xfp
        mda 1
            no shutdown
        exit
        no shutdown
----------------------------------------------
A:SASR6>config>card#

Configuration notes for provisioning of cards

The following provisioning guidelines and restrictions apply:

  • On 7210 SAS systems that require provisioning of the card type (7210 SAS-R6 and 7210 SAS-R12), if a card type is installed in a slot provisioned for a different type, the card will not initialize.

  • On 7210 SAS systems that require provisioning of a card (7210 SAS-R6 and 7210 SAS-R12), if the card is installed in an unprovisioned slot, it will remain administratively and operationally down until the card type is specified.

  • Ports cannot be provisioned until the slot and card type are specified, on systems that require provisioning of the card. Ports can be provisioned on bootup on systems that auto-provision the cards (7210 SAS-T, 7210 SAS-Sx/S 1/10GE, and 7210 SAS-Sx 10/100GE).

Configuration notes for provisioning of 7210 SAS-R6 IMMv2 (IMM-b) cards

The 7210 SAS-R6 platform supports IMM version-2 cards (imm-sas-b variants). To use IMMv2 cards, you must provision the chassis using the config>system>chassis>allow-imm-family CLI command as shown below. This command allows the software know which version of cards will be used in the system and allows it to initialize the system appropriately with the correct set of parameters. A change to this value requires a reboot of the chassis.

 config>system>chassis#
         allow-imm-family imm-family

where:

imm-family = imm-sas-r-b | imm-sas-r-c

  • imm-sas-r-b: use for IMMv2

  • imm-sas-r-c: use for IMM-c

For the list of IMMs supported in a particular release, see the release notes.

The user can change the value of allow-imm-family at any time. It does not change the operational state of the chassis. For the value to take effect, the user must reboot. If the software detects a mismatch in the cards specified by allow-imm-family and the IMM cards provisioned/equipped in the chassis, it will generate an error as shown below.


*A:NS140500018# /configure system chassis allow-imm-family ?
  - allow-imm-family <imm-family>
  - no allow-imm-family

<imm-family>         : imm-sas-r-b|imm-sas-r-c
*A:NS140500018# /configure system chassis allow-imm-family imm-sas-r-b 
INFO: CHMGR #4004 Configuration changes successful. Reboot the chassis for configura
tion to take effect.

Use the following command to display a list of supported cards per family.

Configuration notes for provisioning of 7210 SAS-R6 IMM-c cards

The user has the option to aggregate 1G and 10G customer services to 100GE uplinks to meet the increasing bandwidth needs in access networks by provisioning 7210 SAS-R6 IMM-c cards. The QSFP28 (named imm-sas-c-1qsfp28) variant is supported, providing the flexibility of using optics based on needs.

Before using the card, the command config>system>chassis>allow-imm-family imm-sas-r-c must be used, followed by a reboot of the node to allow the system to initialize correctly when using the new card.

On both the 7210 SAS-R6 and 7210 SAS-R12, imm-b and imm-c can be used simultaneously (that is, some slots can be populated with imm-b and some slots can be populated with imm-c). To achieve that, configure both imm-sas-r-b and imm-sas-r-c using the CLI command config>system>chassis>allow-imm-family. The system scaling of the functions supported when a mix of IMM-b and IMM-c are in use in the chassis is the lower of the scaling supported by each of the cards. See the scaling guide or contact your Nokia representative for more information.

 config>system>chassis#
         allow-imm-family imm-family

where:

imm-family = imm-sas-r-b | imm-sas-r-c

  • imm-sas-r-b: use for IMMv2

  • imm-sas-r-c: use for IMM-c

The following guidelines and restrictions apply:

  • IMM-c supports hot-swapping (after one-time configuration of the node).

  • On the 7210 SAS-R6, only two 100GE IMM-c cards in specified slots can be used. On the 7210 SAS-R12, all slots can be populated with 100GE IMM-c cards.

  • SyncE (as a reference and for distribution of frequency) and PTP (IEEE default and G.8265.1 profile) are available for use with the 100GE port.

  • Supports eight egress queues per network port for egress queuing and scheduling, along with MPLS EXP based marking, for prioritizing service traffic on network uplinks. Supports network port ingress classification with policing and network IP interface ingress classification with policing to differentiate and prioritize service traffic.

  • 100GE QSFP28 IMM-c variant does not provide a breakout option.
