Hello, this switch supports 802.3bj, and also supports the use of FEC on 100G ports, which are enabled by default on 100G ports. От J***u 25/06/2020

Yes, the S58 series switches support the vlan mapping/rewriting. От C***o 15/05/2020

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. От T***r 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. От R***n 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. От D***s 27/02/2020

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.

Thanks for your question. Our S5850-48S2Q4C switch does not support PBB-TE. От *** 06/08/2019

Thanks for your question. The S5850-48S2Q4C switch supports MLAG which enables same ability as stacking. The Ethernet Configuration Guide shows how to configure MLAG for your reference. От *** 04/06/2019

Hello, forwarding ASIC of the S5850-48S2Q4C is developed by ourselves, and it has great data exchange capability and supports multiple protocols, including VXLAN, MLAG, BGP etc. Plus, thank you for your advice. We'll add the chip info on the data sheet very soon. От *** 16/04/2019

Yes, the S5850-48S2Q4C switch can support Qos. And to implement rate-limit on a per-port/SVI basis in both egress & ingress, you just have to create a VLAN through the ACL and configure line rate under SVI or other normal interfaces. От T***m 18/01/2019
