access-uplink operating mode
Description
Commands in this context allocate ingress internal TCAM resources.
The ingress internal TCAM resource pool is shared by multiple features. The resources are allocated in
chunks of fixed size; multiple features cannot share the same chunk. The users can allocate the available
resources based on their feature scaling requirements. The resource usage for different features is
provided in the CLI description. The system allocates resources to the feature from its allocated chunk until
the chunk runs out of resources. The users can reallocate chunks of resources from features that do not
need to be enabled.
To free up the resources for use by one or more features, modify the configuration to release chunks of
resources that are in use by other features. For example, to free up a chunk of resources allocated to
ingress ACLs MAC criteria and allocate the chunk to IP criteria, perform the following steps.
1. Remove the association of all the SAPs with ingress ACLs that use a MAC criteria policy.
2. Change the resource profile configuration to allocate the chunk to IP criteria.
3. Create (can be done before hand) and associate the SAPs with IP criteria.
For another example, to free up a chunk of resources used by ingress ACLs and allocate it towards SAP
ingress QoS classification, perform the following steps.
1. Remove the association of all the SAPs with ingress ACLs.
2. Change the resource profile configuration to reduce the chunk resources allocated to ingress ACLs (and
also to reduce the amount configured for specific match-criteria).
3. Allocate the chunk of resources to SAP ingress QoS classification feature.
4. Configure the SAPs with the SAP ingress QoS policies.
The following table describes the sharing of the ingress internal TCAM resource pool among the features
on different 7210 SAS platforms.
