bash - Correct mrtg cfgmaker file

Question

mrtg cfgmaker does read incorrect values over SNMP V1 and V2 and I need to correct the resulting file.

I would like to run a script after creation and use sed if possible. Lines that needs to be corrected in my case are for LAG's and normal ports:

MaxBytes[switch01_lag_26]: 125000000 should go to MaxBytes[switch01_lag_26]: 250000000

(switch01_lag_26 can be switch01_lag_1 until switch01_lag_26)

MaxBytes[switch01_g1]: 12500000 should go to MaxBytes[switch01_g1]: 125000000

(switch01_g1 can be switch01_g1 until switch01_g16)

What sed patterns I have to use to analyze if its a lag or port in the square brackets and then replace the number after the : ?

The html part should show the correct speed if possible too, this is original for port g1:

                        </table>
                </div>

I can change all speeds in HTML using sed -i 's/([0-9.]+) MBytes/125.0 MBytes/' /switch01.cfg but this changes for LAG's too. How to detect if the HTML part belongs to a LAG?
