TCAM carving can be tricky and requires careful planning to ensure that you have enough resources allocated for all the features you require. Here are a few suggestions that may help you allocate the necessary TCAM resources for L3 Access Lists, ARP Suppression, and QoS on Fex-Ports on your 9332PQ Leaf Switches:
-- Allocate a larger TCAM region for L3 Access Lists: L3 Access Lists require a significant amount of TCAM resources, so you may need to allocate a larger TCAM region for them. You could try increasing the size of the "racl" region to 2048 or even 4096 to accommodate your L3 Access List requirements.
-- Combine ARP Suppression and QoS into a single TCAM region: ARP suppression and QoS can both use the "ns-l3qos" TCAM region, so you could consider combining them into a single region to save TCAM resources. For example, you could allocate 128 entries for ARP suppression and 128 entries for QoS within the "ns-l3qos" region.
-- Consider reducing the size of the SVI TCAM region: SVI counters require a significant amount of TCAM resources, so you could consider reducing the size of the "svi" region to free up TCAM resources for other features. You could try reducing it to 256 or even 128 entries, depending on your specific requirements.
-- Use TCAM sharing: If you have multiple leaf switches in your fabric, you could consider using TCAM sharing to share TCAM resources between switches. This can help you optimize your TCAM usage and ensure that you have enough resources allocated for all the necessary features.
It's important to note that TCAM carving requires careful planning and testing to ensure that all the necessary features are working correctly
