------------------------------------------------
Mr. xxx，
I’ve checked the description about the “alarm LED”,I’m sorry that “Juniper Network” doesn’t provide an official document about the bug of “alarm LED”.
Here are my suggestions toward this challenge:
At the first beginning, let the customer realize that:
The alarm LED is just a signal to notice the network administrator that there had attack but blocked by firewall.
The flowing is official description provide by Netscreen:
The alarm led can,The alarm message needs to be deleted first? From the command line interface (CLI):
clear alarm traffic [Enter]
clear alarm event [Enter]
Then, the LED will remain lit until the following CLI command is issued:
clear led alarm [Enter]
For ScreenOS 4.0.1r1 and higher, you dont need to clear the logs before you clear the led alarm?
The Reasons including:
Attacking; get alarm event
Virus;
CUP or Memory Usage; get alarm threshold
Logging is full; get log event
Session connection is too big;
To slake the LED: clear led alarm
To find out reasons:get alarm event
------------------------------------------------
简单说下：
1、
NetScreen-> get alarm ?
snapshot
threshold
traffic
