Description
Commands in this context configure the CAM resources available in the SF/CPM.
The sf-ingress-internal-tcam resource pool is shared by multiple features. The resources are allocated
in chunks of fixed size. The user is provided an option to allocate the available resources based on their
scaling requirements for the features. The resource usage for different features is provided in the CLI
description for the feature. Resources are allocated to features in chunks of fixed size. It is not possible
to for a chunk to be shared by multiple features. There are a few exceptions which are specified explicitly.
The software allocates resources from the chunk to the feature to which it is allocated until it runs out of all
resources in the chunk. If available, user can allocate more chunks to the feature (by taking away chunks
of resources from other features which do not need to be enabled).
To free up the resources for use by other features, users need to modify the configuration such that the
chunks of resources in use by other features are freed. For example, to free up a chunk of resources
allocated to UP MEPs and allocate it to P2MP LSPs, user will need to remove the configuration of UP
MEPs for all the SAPs, then change the resource profile configuration to allocate the chunk to P2MP LSPs.
Another scenario would be, to free up a chunk of resources and allocate it to another feature.
The sf-ingress-internal-tcam resource pool is shared among the following features on different platforms:
• 7210 SAS-R6 and 7210 SAS-R12
It is global per node resource pool. It is shared among UP MEPs, G8032 Fast-flood, and NG-MVPN
P2MP LSPs.
Note:
• While reassigning chunk of resources among features, in some scenarios a reboot of the node
might be required. See the CLI description of the specific feature to know more.
• The number of chunks and the number of resources per chunk varies among the different
platforms. Contact your ALU/Nokia representative for more information.
• On 7210 SAS-R6, the number of resources per slice/chunk varies. Hence, the number of
resources allocated to a feature varies based on the order of allocation of resources among
the different features. It might be necessary to allocate more slices to a feature to achieve
desired scaling.
• For some features a minimum number of chunks (greater than 1) must be allocated to enable
the feature functionality. If this is not done software cannot allocate the required number of
resources and it will fail the command associated with the feature.
