How to change advertised speed for the 10G GBIC to 1G in R80.10?

[Vladimir]

If I am reading this right, it should be possible:

MACP01> show asset network
Number of line cards: 3
Line card 1 type: 4 ports 10GbE SFP+ Rev 1.0
Line card 2 type: 8 ports 1GbE RJ45 Rev 2.0
Line card 3 type: 2 ports 10GbE SFP+ Rev 2.0

There is a hotfix available for the R77.30, but i do not see anything for R80.10, nor are there any means within WebUI to achieve the same:

How to restrict the advertising of specific speed on multi-speed 1G/10G Fiber interfaces that use IX... 

Although it is a pretty convoluted solution.

If you know of a way to do the same in R80.10, please let me know.

Thank you,

Vladimir
