SR88 隧道口配置netstream，统计的信息包括哪些？统计内层还是外层？

Netstream上可以通过命令查看发送统计及缓存数据，除此之外可以抓取Netstream管理口报文，来确认是否发送正常。

首先在命令行下查看统计：

display ip netstream export //用来查看NetStream统计输出报文的各种信息。
IP export information:
  Stream source interface                        :
  Stream destination VPN-instance                :
  Stream destination IP (UDP)                    : 172.31.0.232 (3000)
  Version 5 exported stream number               : 0
  Version 5 exported UDP datagram number (failed): 0 (0)
  Version 9 exported stream number               : 1679
  Version 9 exported UDP datagram number (failed): 1679 (0)

MPLS export information:
  Stream source interface                        :
  Stream destination VPN-instance                :
  Stream destination IP (UDP)                    : 172.31.0.232 (3000)
  Version 9 exported stream number               : 0
  Version 9 exported UDP datagram number (failed): 0 (0)

display ip netstream cache //用来查看NetStream流缓存区的配置和状态信息。
IP netstream cache information:
  Stream active timeout (in minutes)  : 30
  Stream inactive timeout (in seconds): 30
  Stream max entry number             : 2500000
    IP active stream entry number     : 3
  MPLS active stream entry number     : 0
    L2 active stream entry number     : 0
  IPL2 active stream entry number     : 0
    IP stream entry been counted      : 1679
  MPLS stream entry been counted      : 0
    L2 stream entry been counted      : 0
  IPL2 stream entry been counted      : 0
  Last statistics reset time          : 04/26/2000, 12:30:57
