From ImageStream Router Documentation

Jump to: navigation, search
This chapter describes how to operate the ImageStream router's SAND service. Configuration information for LAN and WAN devices is contained in previous chapters. This chapter includes the following topics:
  • Configuring network interfaces using SAND
  • Enabling network interfaces at boot-time
  • Disabling network interfaces at boot-time
  • Starting the network interface service
  • Stopping the network interface service
After logging in, the main menu is displayed (your menu may look slightly different):
     ISis-Router main menu 
     1. Configuration menu 
     2. Show interface status 
     3. Advanced 
     4. Router software management 
     5. Backup/Restore 
     6. halt/reboot 0. Log off
Select menu option 1, Configuration menu, and press Enter to configure the router. The Configuration menu should appear (your menu may look slightly different):
     Configuration menu 
     1. AAA (Password) Configuration 
     2. Global configuration 
     3. Network interface configuration 
     4. Firewall and QOS configuration 
     5. Service configuration 
     6. Dynamic routing configuration 
     7. Save configuration to flash 
     0. ISis-Router main menu
Next, select menu option 3, Network interface configuration, and press Enter. Otherwise, select menu option 5, Service configuration menu, and press Enter to configure the router's service configuration settings. The Service configuration menu will be displayed (again, your menu may look slightly different):
     Service configuration 
     1. System scheduler (cron), (running) 
     2. Dialout PPP, (stopped) 
     3. IPSec VPN (Free S/Wan), (stopped) 
     4. NetFlow exporter (nprobe), (stopped) 
     5. network interfaces (sand), (running) 
     6. sconsole (mgetty), (running) 
     7. snmp (net-snmp), (stopped) 
     8. ssh (OpenSSH), (running) 
     0. Configuration menu
Select menu option 5, Network interfaces, and press Enter to configure the router's network interface settings. The network interface menu will be displayed (again, your menu may look slightly different):
     network interfaces (sand), (running) 
     1. Configure network interfaces 
     2. Enable network interfaces on boot 
     3. Disable network interfaces on boot 
     4. Start network interfaces 
     5. Stop network interfaces 
     0. Service configuration 
To configure SAND, select menu option 1, Configure network interfaces, and press Enter. This will open the default network interface configuration file (wan.conf) in your default text editor. See Chapter's 5 and 7 for information on configuring LAN and WAN devices on an ImageStream router.

Enabling Network Interfaces at Boot-time

2. Enable network interfaces on boot
Selecting this menu option enables the network interface configurations when the router is booted. This does not start the network interface service on the router if it is not running, unless the router is rebooted first. By default, the network interface configuration is enabled on boot. To enable network interfaces on boot, select this menu option by pressing 2 and Enter. The router will display the following message:
     sand enabled on boot. 
If the network interface configuration has already been enabled on boot, the router will display the message:
     sand already enabled on boot. 
The resulting message will only be displayed for a few seconds, and then you will be returned to the Network interfaces menu.

Disabling Network Interfaces at Boot-time

3. Disable network interfaces on boot
Selecting this menu option disables the network interfaces when the router is booted. This does not stop the network interface service if it is running, unless the router is rebooted first. To disable the network interface service on boot, select this menu option by pressing 3 and Enter. The router will display the following message:
     sand disabled on boot. 
If the network interface service has already been disabled on boot, the router will display the message:
     sand already disabled on boot. 
The resulting message will only be displayed for a few seconds, and then you will be returned to the Network interfaces menu.

Starting the Network Interface Service

4. Start network interfaces
Selecting this menu option starts the network interface service on the router. Starting the network interface configuration does not automatically enable the network interfaces when the router is booted. To start the network interface service, select this menu option by pressing 4 and Enter. The router will display the following message:
     Starting sand...done. 
The message will only be displayed for a few seconds, and then you will be returned to the Network interfaces menu.

Stopping the Network Interface Service

5. Stopping network interfaces
Selecting this menu option stops the network interface service on the router. Stopping the network interface configuration does not automatically disable the network interfaces when the router is booted. To stop the network interface service, select this menu option by pressing 5 and Enter. The router will display the following message:
     Stopping sand...done. 
The message will only be displayed for a few seconds, and then you will be returned to the Network interfaces menu.

Returning to the Service Configuration Menu

0. Service configuration
Selecting this menu option returns you to the "Service configuration" menu. To return to the Service configuration menu, press 0 and Enter. The router will display the Service configuration menu:
     Service configuration 
     1. System scheduler (cron), (running) 
     2. Dialout PPP, (stopped) 
     3. IPSec VPN (Free S/Wan), (stopped) 
     4. NetFlow exporter (nprobe), (stopped) 
     5. network interfaces (sand), (running) 
     6. sconsole (mgetty), (running) 
     7. snmp (net-snmp), (stopped) 
     8. ssh (OpenSSH), (running)
