sSrv13 expected result states the Beh values on the lower level LN0/LN. However it does not state anything about the lower level Mod values. It's obvious that the lower level Mod values should not change (only the highest level Mod value changes).

Proposal is to add to the expected result step 3: "lower hierarchy Mod values do not change"

Agree with the editorial proposal. Nevertheless, it is not beccause it is missing in the current TP1.2 in sSrv13 that it is allowed to change Mod.stVal in lower hierarchy.

Should the text in 7-1, clause 8.2.5 be changed for clarity? It says that the mode of the LNs in a lower level may be changed individually or globally by means of LLN0 of LD3. Their mode may also be changed either by means of LLN0 of LD2 or by means of LLN0 of LD1.

So this seems to be saying that the mode in the lower level will change.

TPWG agrees this is and has been expected functionality, should be tested immediately for new test (PO received).

For devices currently in test, tester should inform the vendor and recommend change to comply.

The certificates that reflect the revised test procedure of this issue, shall have the note: Tested per Redmine Issue 6710: Proper behavior of Mod

When a revised Test Procedure document becomes mandatory, that includes the revised test procedure, the note shall not appear on the certificate.
