What Are Differences Between the Outbound Traffic Policing and Traffic Shaping
Both outbound traffic policing (TP) and traffic shaping (TS) limit the rate of outgoing traffic on an interface. Traffic policing and traffic shaping have the following differences: -Traffic policing directly discards packets with rates that are greater than the traffic policing rate. Traffic shaping, however, buffers packets with rates that are greater than the traffic shaping rate and sends the buffered packets at an even rate. -Traffic shaping increases the delay, whereas traffic policing does not.

Bit error detection mechanism of a 2M tributary board
Bit error detection mechanism of a 2M tributary board: A 2M tributary board performs bit error detection for signals transmitting from a cross-connect board to the 2M tributary board, and does not perform bit error detection for 2 Mbit/s signals received from the PDH physical port on the 2M tributary board.

Different solutions for external 2M clocks of OSN 8800 and OSN 6800 devices
In OSN 8800, clock signals and frame headers do not need to pass the cross-connect board but the status signals are bound. In addition, the STG board of OSN 8800 must work with the cross-connect board. In OSN 6800, clock signals and frame headers do not need to pass the cross-connect board. Active/standby switching is implemented for cross-connect boards and STG boards in an associated way.

Question about packet loss when the rate of ping packets is high on S series switches
When another device pings an S series switch (a non-S1700 switch), the device and the switch exchange ICMP packets. To protect the CPU, you can run the icmp rate-limit command to configure a rate threshold for ICMP packets. The undo icmp rate-limit command restores the default rate threshold of ICMP packets.
