MCU-PLUS-SDK-AM243X: VLAN entry in ALE

Hussein Hafez

Hello,

I am using Am243x-lp and I added VLAN entry with ID to port1 in ALE and when I tried to delete this VLAN using `CPSW_ALE_IOCTL_REMOVE_VLAN` it gives me error and I can not track what is wrong because I used the same to delete OUI entry and unicast entry and everything is working fine

void L2EntryTable_vDeleteVlanEntry(EnetApp_PerCtxt *perCtxt, uint32_t u32VlanId)
{
CpswAle_VlanEntryInfo sVlanEntryInfo;
Enet_IoctlPrms sParameters;
int32_t s32Status;
memset(&sVlanEntryInfo, 0U, sizeof (CpswAle_VlanEntryInfo));
sVlanEntryInfo.vlanIdInfo.vlanId = u32VlanId;
sVlanEntryInfo.vlanIdInfo.tagType = ENET_VLAN_TAG_TYPE_INNER;

ENET_IOCTL_SET_IN_ARGS(&sParameters,&sVlanEntryInfo)
ENET_IOCTL(perCtxt->hEnet,gEnetApp.coreId,CPSW_ALE_IOCTL_REMOVE_VLAN,&sParameters,s32Status);
if (s32Status != ENET_SOK)
{
EnetAppUtils_print("L2EntryTable_vDeleteVlanEntry() failed CPSW_ALE_IOCTL_REMOVE_ADDR: %d\n", s32Status);
}
else
{
EnetAppUtils_print("VLAN Entry Deleted: \n\r");
}

}

I added entry with VLAN ID = 20 and I pass to this function u32VlanId = 20 and this error appears.

Hi Hussein Hafez ,

Can you please help me to reproduce the issue on my setup ?

Which SDK example you are working on ?

What are local changes on your setup ?

Regards

I am using "mcu_plus_sdk_am243x_09_01_00_41", I changed the ALE to be in VLAN aware mode, ports to have VLAN, CPSW ALE enabled and no learning for each port and enable MAC authentication

Hi Hussein Hafez,

As we do not have any out of box example for VLAN addition/ deletion.

I created below patch for C:\ti\mcu_plus_sdk_am64x_09_00_00_35\examples\networking\lwip\enet_cpsw_tcpserver

/cfs-file/__key/communityserver-discussions-components-files/908/add_5F00_delete_5F00_vlan_5F00_entry.patch

Let me know if you have any concern here ?

Did this example works on your side and the error does not appear?

Hi Hussein Hafez ,

Thanks for follow-up.

We are also able to reproduce the problem with CPSW_ALE_IOCTL_REMOVE_ADDR.

Will get back to you with timeline of the fix as soon as I get it from dev team.

Hi Hussein Hafez,
We had analyzed the issue and root caused it to wrong input arguments.

Here is the correction to your code-

void L2EntryTable_vDeleteVlanEntry(EnetApp_PerCtxt *perCtxt, uint32_t u32VlanId)
{
-   CpswAle_VlanEntryInfo sVlanEntryInfo;
+   CpswAle_VlanIdInfo sVlanEntryInfo
    Enet_IoctlPrms sParameters;
    int32_t s32Status;

    memset(&sVlanEntryInfo, 0U, sizeof (CpswAle_VlanEntryInfo));


-   sVlanEntryInfo.vlanIdInfo.vlanId = u32VlanId;
-   sVlanEntryInfo.vlanIdInfo.tagType = ENET_VLAN_TAG_TYPE_INNER;
+   sVlanEntryInfo.vlanId = u32VlanId;
+   sVlanEntryInfo.tagType = ENET_VLAN_TAG_TYPE_INNER;


    ENET_IOCTL_SET_IN_ARGS(&sParameters,&sVlanEntryInfo)

    ENET_IOCTL(perCtxt->hEnet,EnetSoc_getCoreId(),CPSW_ALE_IOCTL_REMOVE_VLAN,&sParameters,s32Status);

    if (s32Status != ENET_SOK)
    {
        EnetAppUtils_print("L2EntryTable_vDeleteVlanEntry() failed CPSW_ALE_IOCTL_REMOVE_ADDR: %d\n", s32Status);
    }
    else
    {
        EnetAppUtils_print("VLAN Entry Deleted: \n\r");
    }

}
