Insufficient resource allocation for S12508F-AF

Device model and version: S12508F-AF R1152

Previously, BAGG52 successfully delivered vlan mapping, but after configuration changes were made and qinq enable was activated on the interface, errors occurred when attempting to deliver vlan mapping again.

XG1/2/0/31 reported insufficient resources, while XG2/2/0/31 could be delivered normally.

Error message from the customer's adjustment last night:

[HZD4Z-B-POP-S12508F-IRF-Bridge-Aggregation52] vlan mapping nest range 101 to700 3101 to3500 nested-vlan 3914 

Not enough hardware resources are available to complete the operation on Ten-GigabitEthernet1/2/0/31.

Interface configuration is as follows:

Acknowledge: Enabling QINQ consumes system ACL resources: This will consume ACL resources in the ifp orientation, where each VLAN passing through the port will issue separate ACL matching entries. Therefore, the more VLANs pass through, the more ACL resources are consumed. Here, VLAN refers to the VLANs permitted by the port. Configuring the qinq enable command will consume additional system resources, so it is recommended to configure it only when necessary.

This issue can be resolved by deleting QINQ and reissuing VLAN mapping. At the same time, check whether all VLANs permitted on the interface are necessary. If not, they can be streamlined.
