SFU functions of S12700 switches

18

The ET1D2SFU provides the data plane for the entire system. The data plane provides high-speed, non-blocking data channels for data switching between service modules.
The ET1D2SFU consists of the following functional modules:
- Switching module: functions as the data plane and provides high-speed service channels for data switching.
- Local clock module: provides the working clock for the chips of the switching module, management module, and monitoring module on the ET1D2SFU.
- Power module: provides power supply for the ET1D2SFU.

S12700 SFU clustering
The S12700 uses a hardware architecture that separates the switching plane from the control plane. It has independent SFUs, and the CSS card is installed on the SFU. Packet forwarding is not affected when the S12700 has no MPU installed. This architecture allows two S12700s to set up a CSS with no MPU installed on the standby switch. 1+N backup of MPUs enables a CSS to run stably as long as one MPU of any chassis in the CSS is working normally.

Is S12700 the only S series switch that supports SFUs
The S12700 and S9310 support independent SFUs. The S12704 supports ET1D2SFUA000 and ET1D2SFUC000. The S12708 supports ET1D2SFUA000, ET1D2SFUC000, ET1D2SFUD000, and ET1D2SFUB000. The S12712 supports ET1D2SFUA000, ET1D2SFUD000, and ET1D2SFUB000. The S12710 supports ET1D2SFUB000. The S9310 supports LE1D2SFUK000.

What are the functions of the eUSB card of the S12700
The S12700 series switches support standard eUSB cards. The default capacity of an eUSB card is 2 GB, expandable to 4 GB or 8 GB. The eUSB card is used to store system files, configuration files, paf, License, and log files. The S12700 series switches can start by using the startup file in the eUSB card. In this case, the system software package is stored on the eUSB card. It is required to specify the system software package on the eUSB card as the boot file. On the S12700 series switches, logs can be stored on the eUSB cards. Do not use the uncertified eUSB cards to prevent unpredictable problems.
