在ALEX里面,关于un-Acknowledge 是这样描述的:
Configuring Un-Acknowledge ModeThe [url=]APN[/url] can optionally be configured to ignore the Accounting-Response messages sent from the [url=]RADIUS[/url] server. This is referred to as [url=]RADIUS[/url] un-acknowledge mode. To configure [url=]RADIUS[/url] un-acknowledge mode, include the following statement: [edit services epg pgw apn apn-name radius accounting]un-acknowledge;本人理解是添加了这条配置pdp的建立就不需要等待radius的鉴权回复,这样可以减少PDP 建立的时延,但有一个问题是,如果忽略radius 回复,就相当于无论鉴权失败与否,都会建立pdp,那radius不就失去作用了???
