+
+To delete ACLs applied on NNI or External Network resources, pass a null value to `--ingress-acl-id` and `--egress-acl-id`.
+
+1. Update the NNI or External Network by passing a null ID to `--ingress-acl-id` and `--egress-acl-id`.
+
+```Azure CLI
+az networkfabric nni update --resource-group "<resource-group-name>" --resource-name "<nni-name>" --fabric "<fabric-name>" --ingress-acl-id null --egress-acl-id null
+```
+
+| Parameter            | Description                                                                                      |
+|----------------------|--------------------------------------------------------------------------------------------------|
+| `--resource-group`   | Name of the resource group containing the network fabric instance.                              |
+| `--resource-name`    | Name of the network fabric NNI (Network-to-Network Interface) to be updated.                    |
+| `--fabric`           | Name of the fabric where the NNI is provisioned.                                                     |
+| `--ingress-acl-id`   | Resource ID of the ingress access control list (ACL) for inbound traffic (null for no specific ACL). |
+| `--egress-acl-id`    | Resource ID of the egress access control list (ACL) for outbound traffic (null for no specific ACL). |
+
+> [!NOTE]
+> Based on requirements, either the Ingress, Egress, or both can be updated.
+
+2. Execute `fabric commit-configuration`. 
+
+```Azure CLI
+az networkfabric fabric commit-configuration --resource-group "<resource-group>" --resource-name "<fabric-name>"
+```
+
+| Parameter        | Description                                                  |
+|------------------|--------------------------------------------------------------|
+| `--resource-group` | The name of the resource group containing the Nexus Network Fabric. |
+| `--resource-name`  | The name of the Nexus Network Fabric to which the configuration changes will be committed. |
+
+4. Verify the changes using the `resource list` command.
+
+
+### Deleting ACL Associations from NNI
+
+To disassociate only the egress ACL from an NNI, use the following command:
+
+```Azure CLI
+az networkfabric nni update --resource-group "example-rg" --resource-name "example-nni" --fabric "example-fabric" --egress-acl-id null
+```
+
+Example Output:
+
+```Output

+    },
+    "type": "microsoft.managednetworkfabric/networkfabrics/networktonetworkinterconnects",
+    "useOptionB": "True"
+}
+```
+
+To disassociate both egress and ingress ACLs from an NNI, use the following command:
+
+```Azure CLI
+az networkfabric nni update --resource-group "example-rg" --resource-name "example-nni" --fabric "example-fabric" --egress-acl-id null --ingress-acl-id null
+```
+
+These commands allow for the disassociation of ACLs from NNIs within the specified Nexus Network Fabric. Ensure to replace placeholders with actual resource group and NNI names for accurate execution.
