Juniper ERX erasing Console Password
1. Reboot the router by pressing the recessed software reset button on the primary SRP module (see Figure 29) and then pressing the <mb> key sequence during the countdown.
2. Disable authentication at the console level.
:boot##disable console authentication
If you remember the password at this point, you can override this action by
entering:
:boot##no disable console authentication
3. Reload the operating system.
:boot##reload
When the operating system reloads, you can access the console without a password.

其中的committed burst 建議設定法
The recommended burst sizes for TCP-friendly behavior are:
! Committed burst – 0.2 to 2.0 seconds of the committed rate
! Excess burst – 1.0 to 2.0 seconds of the committed rate, plus the committed
burst
For example, if the committed rate is 2,000,000 bps, we recommend:
! Committed burst is 1,000,000 x 1.0 x 1/8 = 125,000 bytes
! Excess burst is 1,000,000 x 1.5 x 1/8 + 125,000 = 312,500 bytes
