omcicli mib get 84 return valid data only when using 2 VLAN.

Hey!
I'll demonstrate how I handled Brazil's BLINK TELECOM ISP and ask for support.

Using this operator, I need to run the command omcicli mib set 84 0x01 FwdOp 0x02 everytime at boot.

So, I did a change to the firmware:

I created a script (attached) at /etc/scripts/fix_vlan_tag.sh .

then, you need to set the value of one variable, /etc/config/EntityID.txt:

echo 0x01 > /etc/config/EntityID.txt

Now, every time that it boots, it will run the command omcicli mib get 84. If the table is populated, then it run the command omcicli mib set 84 $EntityID FwdOp 0x02, where $EntityID = the value at /etc/config/EntityID.txt

An interesting detail is that with this ISP, I can only get it to work if I have VOIP. If the contract does not include VOIP, omcicli mib get 84 does not return anything.

I need help with this question:

When you pay for VOIP, BLINK TELECOM activates one more VLAN (normally 40) for VOIP, in addition to the default (1011) for PPPoE.
Why, without the VOIP VLAN (40), with only one VLAN, omcicli mib get 84 returns nothing?
In this scenario, diag l2-table get entry address valid shows several MACs, indicating that I can reach the ISP network.

Do you know anything about this behavior?
If anyone is interested, I can also send the complete image with my modifications.
