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. Both the QSFP28 (named imm-sas-c-1qsfp28) and CFP4 (named imm-sas-c-1cfp4) variants are 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.
