Issue Description

Q: 
How to solve the loss of ping NE5000E interface address?

Alarm Information

Null

Handling Process

A:
1. The analysis of the loss:
All packets sent to CPU have speed-limit. The maximum rate of ping packet sent to CPU is 2M. If the source sending rate of ping is rapid, the loss occurs.
2. Solutions (suppose the maximum rate is 8M):
1) For LPUA (2800 intel network processor)  and rainer (NE40/80), use the following command:
[NE5000E]cpcar ipv4-icmp slot <slot-num> 
[NE5000E-cpcar-ipv4-icmp-slot-<slot-num>]car cir 8000
2) For LPUB and LPUC (588 processor), use the following command:
[NE5000E]cpcar other-prcl slot <slot-num> 
[NE5000E-cpcar-other-prcl-slot-<slot-num>]car cir 8000
