The switch could not support the route leak function described above currently. Par B***y le 28/06/2020

The maximum VLAN counting number is 128. Par P***d le 20/05/2020

The interface defaults to L2 mode. Under L2, the frame size of jumbo frames is a fixed number -9216. If you want to change it, you can only configure the frame size by setting the MTU value in L3 mode. Par M***a le 14/05/2020

MLAG and STP functions can't be used together in S58 series switches. Par W***l le 08/05/2020

There is no difference between IP Base and IP Service. We have opened all advanced features for free. However, the 7.2.1ver of the S5850 series switches requires the license which will cost USD$500 to support MPLS and EVPN functions. Par T***r le 08/04/2020

1. Multi-Protocol Label Switching is a new technology that uses labels to guide high-speed and efficient transmission of data on an open communication network. The meaning of multi-protocol means that MPLS can not only support multiple protocols at the network layer level, but also be compatible with multiple data link layer technologies of the layer. 2. FS S5850 series switches support MPLS. If you need L3 VPN, you have to update to version 7.2.1 or above, and buy the lincese. Par R***n le 15/03/2020

MLAG has an anti-loop mechanism, which can construct an acyclic network. Therefore, STP (Spanning Tree Protocol) is not required. Please turn off it, and the command is: no spanning-tree enable. Please refer to the configuration case of the document to configure the MLAG. Par D***s le 27/02/2020

Store-and-Forward and Cut-Through are both switches' forwarding modes, but they have different preferences: 1. Store and forward will store and check the data frame before forwarding. So it will be have higher delay and lower speed. 2. Cut Through will forward data fraome as soon as receiving the header of data frame. So it is faster without check round. Par J***e le 24/02/2020

Don't worry, this is determined by the load mode when the link aggregates and forwards data. The data transmission of link aggregation keeps changing. S5850 uses a stream-by-stream load, so the maximum link rate cannot be reached maximum during the test; and the packet-by-packet load can reach the highest rate, but not very stable so choose stream-by-stream.

Yes, the 25G ports can be configured at 10 and 25G speed. And wire-speed fowarding is independent of buffer. As S5850-24T16B, the default mode is cut-through. In this mode, buffer is relatively small and single port supports 288KB ideally. And you can switch to store-and-foward mode, as for unicast traffic, the buffer of single port is about 1.4MB. If you have high requirement for buffer, we recommand you S5850-48S6Q, S5850-48T4Q and S5850-32S2Q. Par D***k le 14/02/2020
