Hello friend

Note that the value before the slash (/) refers to the device's switching capability, while the value after the slash (/) means the chip's switching capability.

Hello
From what I see in the documentation, the S5731 series switches have a Switching capacity of 672 Gbit/s, and a Forwarding performance of 85 Mpps (S5731-S24T4X and S5731-S24P4X) and 105 Mpps (S5731-S48T4X and S5731-S48P4X).
Note: Mpps (Millions of Packets per Second).

Note that switching capacity depend on number of ports so two switch of the same family can have probably the same chip installed (same chip's switching capability) but different number of ports so differents switching capability. The chip's switching capability can give you the idea of how powerful is the chip installed.

Like phones, different models of phones may have chips of the same model, but their performances are different.
Therefore, the last value just indicates that chip performance is sufficient. The previous value indicate real capability.

Hello!
I think that second value (chip capacity) can be used as a requirement in the order to clarify the object of the purchasing. That is related to my country.
