Alarm Information
Handling Process
modify the parameter of flow control in SecureCRT , the problem is solved.

By default , the parameter of "RTS/CTS" is selected , cancel it then login , the freezon issue disappear , everything becomes working fine.

Root Cause
1. check the booting process, no abnormal things , no alarm , the booting should be ok.

2. user is login the router with the tool of SecureCRT through console port , try to advice to login router with another tools such as Putty , It's no similar issue when using Putty to login . doubt it's caused by the tool .
most of loginning issues caused by the setting of flow control parameter when using SecureCRT to login device , pay attention to that and cancel the parameter of "RTS/CTS" , the freezon issue can be solved in most circumstances .
