Q5: What is sniff subrating mode, and what is its relationship with sniff mode? The so-called sniffsubrating mode uses fewer sniff anchor points, which can be understood as a longer monitoring interval. It needs to be in sniff mode first, and then have a timeout. If there is no data transmission of ACL-C and ACL-U within this timeout, it will enter sniff subrating mode. If there is one in the middle, the timer will be restarted. On the contrary, if you want to go from sniff subrating mode to sniff mode, you need to exit to sniff mode as long as you receive the ACL data. And if the packet you send needs a response at this time, then if the response does not arrive, you still need to In sniff mode. As shown in Figure 7-4 below.
