Summary:
How to setup a serial Console connection to the NetScreen's communications port using HyperTerminal

Problem or Goal:
Environment:
  • Using a RS232 or RJ45 straight cable to connect from the PC to the Netscreen device.
  • Hyperterminal settings
  • Lost the IP address needed to manage the NetScreen
Symptoms & Errors:
  • Cannot login to the WebUI to manage the device 

Solution:

To determine the IP address of the NetScreen, a direct serial console connection is required. 

  1. Physically hook up the console to the NetScreen on one end, and hook up the other end to the PC's serial connection. 
  2. Launch HyperTerminal (Located in Start->Programs->Accessories->Communications->HyperTerminal
  3. Create a connection name
  4. On the Connect To screen, on the Connect Using pull down menu, select the appropriate COM port for your PC
  5. Configure the serial settings to:
    1. Bits per second: 9600
    2. Data Bits: 8
    3. Parity: None
    4. Stop Bits: 1
    5. Flow Control: None

After HyperTerminal is set up, hit [Enter] a few times until you get to the login prompt, and login to the box.  To determine the IP address, apply the command

get system [Enter]

The get system will tell you what IP address you need to connect to.  If accessing the NetScreen from the untrust side, you will need the manage-ip on the untrust side.  If accessing the NetScreen from the trust side, you will need the manage-ip on the trust side.  If the NetScreen is running transparent mode, you will need the system-ip of the device.

If the device is running 3.1 or higher, the IP address you need is the vlan1 interface ip address.

Additional Information:
Any other serial console program can be used; example TeraTerm, etc.

Purpose:
Troubleshooting
