Does the S5700SI Support Statistics on Jumbo Frames?

Yes,S5720-52X-PWR-SI-AC supports compatible SFP, but the switch may generate alarm, however, it will not affect normal use.

The forwarding chip does not support statistics on Jumbo frames, so the display interface command on the Huawei S5700-SI does not display statistics on Jumbo frames. S5700 Switch Thunder link com

It is not possible to upgrade S5700-24TP-PWR-SI with S5700 V200R010C00SPC600.

you could always contact your Huawei dealer and ask them, if that doesn't seem tooooooo obvious to try doing.

Huawei S5700-28P-PWR-LI only can be equipped with AC 110V-220V power supply.Only Huawei S5720-28X-PWR-SI, S5720-52X-PWR-SI, S5720-36C-PWR-EI, S5720-56C-PWR-EI can support Huawei PDC-650WA-BE (650W DC PoE module)

Yes, the S5700-SI PWR complies with IEEE 802.3af and 802.3at (PoE+)
And Huawei S5700 Series Enterprise Switches provides LI (Lite), SI (Standard), EI (Enhanced) and HI (Hyper) models for users. There are some differences among these four versions.

An ES5D000G4S01 subcard can only be used on an S5700EI, and an ES5D00G4SA01 subcard can only be used on an S5700SI. If an ES5D000G4S01 subcard is installed on an S5700SI or an ES5D00G4SA01 subcard is installed on an S5700EI, the subcard cannot register.
An ES5D000G4S01/ES5D00G4SA01 front subcard must be used with an ES5D00ETPB00 extended rear subcard; otherwise, only the first two interfaces on the ES5D000G4S01/ES5D00G4SA01 subcard can work.

Fixed optical interfaces on the S5700EI, S5700SI, S5710LI, and S5700HI support 100M optical modules, while interfaces on extended front cards do not support 100M optical modules.

In the S5700LI series, only the S5700-28X-LI-24S-AC, S5701-28X-LI-24S-AC, S5700-52XLI- 48CS-AC, and S5700-28X-LI-24S-DC support 100M optical modules on their GE interfaces.

The S5710EI series switches support 100M optical modules only on their combo interfaces.

When a GE optical interface of the S5700 works at 1000 Mbit/s, it can only use a 1000M optical module. When the interface works at 100 Mbit/s, it can use either a 100M optical module or a 1000M optical module.
