There is a default template called Interfaces by SNMP, inside interfaces discovery there are items "Bits sent" and "Bits received".

Those items are collecting octects count/info with preprocessing steps:

1. Change per second
2. custom multiplier: 8

Since the item update interval is 3mins we will have the difference of octects between 3mins and multiplied by 8 will have value of: Total number of bits transmitted in 3mins. But we have applied directly "bps" in units which is saying: total number of bits transmitted in 1sec.

For example:

1st polling value: 12345678

2nd polling value after 3mins: 134567892 (since 3mins is the item update interval)

Now the preprocessing steps executes:

1. Change per second = 134567892 - 123456789 = 11111103
2. custom multiplier = 11111103 * 8 = 88888824

the value is 88888824 bits transmitted in 3mins of time

but as we have applied units as bps for that item it says 88888824 bits transmitted in 1 sec which is wrong right? its showing 88.8Mbps for Bits sent item where my link is only 25Mbps link.

Please correct me if I'm wrong with any misunderstanding.
