default流量：

没定义
class分类已满，如2500最多支持512个class
p2p等一些非固定端口的流量。
非对称路由，只有request或ask流量通过。

statisics

top ten，可查看流量种类排名，有利于检查优化效果。

response time 只对tcp起作用，对udp无效，可以分析server时延和网络时延。可以检查服务故障是出在网络还是服务器。

 策略：

partation对traffic,policy对flow

pirioty policy。
rate policy

policy

Rate:Guaranteed rate represents the minimum rate guaranteed to each connection in this class when the connection requires it. If a specific minimum rate is not required, set the rate to 0 bps and configure the burstable options below.
Check Burstable to allow a connection to use excess rate, and select a priority level for bursting relative to other traffic classes. Also, set a limit to control how much excess bandwidth the connection can use. If a limit is specified, it must be at least 256.

Priority:Use a Priority policy to specify the priority level for traffic flows.

Never-Admit:Use a Never-Admit policy to reject Web and TCP traffic and restrict non-TCP traffic where applicable.

Ignore:Use an Ignore policy to exempt a traffic class from bandwidth allocation and treat the traffic type as "pass-through" traffic.

Discard:Use a Discard policy to discard packets altogether.

partition

Specify a "size" to reserve bandwidth for all traffic defined by the class and its non-partitioned children. The size can be zero. Set the "burstable" option to allow a partition to borrow available bandwidth from other partitions, up to the "limit" you define. If a limit is specified, it must be at least 1000 bps.

升级软件版本：

ftp://ftp地址, cd

put  software  -   imageload software

删除plg目录下文件，重新上传插件，reset生效。

me reset 清除以前的数据。

恢复出厂设置：setup reset all

常用命令：
