Getting all Network Interfaces working on LS1088ARDB

[reza_m]

I've been trying to set up 10 network interfaces for the 10 ports on the LS1088ARDB. The first 9 dpni get instantiated but when i try to create a 10th dpni object, i get the error that there no resources left.

I ran the following experiment to determine which resource is the limiting factor. I deleted all the existing network interfaces and created each interface with 2 dpcon objects. Each interface could create sufficient dpbp, dpcmp and dpcon objects, however the last interface could not create a 10th dpni object.

I tried instantiating all the dpni's in my dpl file however i'm getting a similar issue i outlined above. I have attached a my dpl file and system log.

Also, I see there is documentation on how many dpcon objects are supported, but I can't find any resources on the limits of other object types.

Thank you,

Now when i try to list my network interfaces or my mac addresses i get this error.

[yipingwang · Accepted solution]

In order to create more, the DPNIs must be created with fewer entries in WRIOP tables, e.g. fs_entries=1 or use DPNI option DPNI_OPT_NO_FS.

restool dpni create --fs-entries=1

You can add the number of flow steering entries directly to the DPL..

Below is an example:

dpni@1 {

        options = "DPNI_OPT_NO_FS";

        fs_entries = <0x1>;

};
