IOLAN Device Server OEM - Configuration - Out of Band Console Management for IOLAN Desktop and Rackmount models that have a Perle internal PCI modem - command line example

Solution:

The following configuration examples use the command line interface.

Desktop models with internal modem port

Step 1:  This is how you would configure the iolan IP address from the command line.   For example, type the commands shown in bold.   

set server internet <ip_address> netmask <subnet_mask>  

example:  set server internet 192.168.1.2 netmask 255.255.255.0

Step 2 and Step 3 are optional and depends on whether you require a gateway.  If no gateway is required then skip Step 2 and Step 3, go to Step 4.. 

Step 2:  Add a host table entry for the gateway (if applicable), type:

add host <hostname> <IP_address of your iolanSDS3M>

for example:   add host gw 192.168.1.1

Step 3:  Add a default gateway entry, type:

add gateway <hostname> default

for example:   add gateway gw default

Step 4:   Configure the internal modem port (line 4).

add host self 192.168.1.2  (enter the IP address of your iolanSDS3M)

set line 4 service silent telnet self 23  

set line 4 termtype vt100

set line 4 connection-method dial-in

set line 4 speed 115200 flow hard

Step 5:   Configure serial line (port) 1 for console management of your Cisco switch.  Type the commands shown in bold. 

set line 1 service reverse telnet 10001

note:  Repeat the above step for any other ports you wish to use for console management.  For example, 

set line 2 service reverse telnet 10002

notes:  The default hardware settings for the port are 9600, 8 data bits, no parity, stop bit, no flow control.  These settings are typically the same for Cisco console management.  However if you need to change the hardware settings here is an example showing how to change the speed and flow control on a given port.  ie.,     set line 2 speed 19200 flow soft

Step 6:  Next add a menu level user.

add user perle  

password:   xxxxxxxx

set user perle level menu

Step 7:    save

Step 8:   reboot

Important Notes 

If using a Desktop model, ensure that the Serial/Console switch is set to the Serial (OFF) position.  If you need to change it to Serial be sure to power the iolanSDS3M off and on after you change the switch settings. 

If you are going to use the Windows Hyperterminal emulation program or equivalent program to dial in with,  configure the properties to match the hardware settings. ie.,  115200, 8 data bits, none parity, 1 stop bit, hardware flow control.  Also, change the emulation in your Hypterterminal or other program properties settings to VT100.   You may need to make adjustments to the speed depending on the quality of your phone lines in your area.   The change would need to be made on both the iolanSCS and your Hyperterminal program.

When you dial and connect you will be prompted for a Login and password.  Be sure to enter the menu level user and password that you configured in the above configuration.  Only the serial ports that were configured for Console Management (reverse Telnet) will appear in the easy port selection menu.  The hotkey to exit out of a session and back to the easy port selection menu  is     ~menu     (do_not press the Enter key after ~menu otherwise you will be logged out and will need to reconnect).

iolan SCS rackmount model with internal PCI modem 

For iolanSCS 8 port the PCI modem port is line 9,   for iolanSCS 16 port the PCI modem port is line 17,   for iolanSCS 48 port the PCI modem port is line 49. 

This example is using an IOLAN SCS 32 port,  therefore Port 33 or line 33 is assigned to the PCI internal modem. 

Therefore,  replace the line number with line nunber of your internal PCI modem.  

Login to the administration port of your iolanSCS.  All commands are shown in bold.

Step 1:  Configure the iolan IP address.  If you have already configured the IP address information then confinue to the next step. 

set  server  internet  eth1  192.168.1.2  255.255.255.0 

Step 2 and Step 3 are optional and depends on whether you require a gateway.  If no gateway is required then skip Step 2 and Step 3, go to Step 4.. 

Step 2:  Add a host table entry for the gateway (if applicable), type:

add host <hostname> <IP_address of your iolanSDS3M>

for example:   add host gw 192.168.1.1

Step 3:  Add a default gateway entry, type:

add gateway <hostname> default

for example:   add gateway gw default

Step 4:  Next configure the internal modem port.  Remember that this example is using an iolanSCS 32 port therefore the internal PCI modem port is line 33. 

reset line 33

save

kill line 33

set pci card modem

add host self 192.168.1.2 

set line 33 service silent telnet self 23  

set line 33 termtype vt100

set line 33 connection-method dial-in

set line 33 speed 115200 flow hard

set line 33 dial-timeout 60

Step 5:  Next configure other serial lines for console management of a serial device such as a CIsco console or Sun console, ...

For example, 

set line 1 service reverse telnet 10001

note: repeat the above for any other ports (lines) to be used for console management.  For example, 

set line 2 service reverse telnet 10002

notes:  The default hardware settings for the port are 9600, 8 data bits, no parity, stop bit, no flow control.   If you need to change the hardware settings here is an example showing how to change the speed and flow control on a given port.  ie.,     set line 2 speed 19200 flow soft

Step 6:  Next add a menu level user (required for the easy port selection menu). 

add user perle  

password:   xxxxxxxx

set user perle level menu

Step 7: save

Step 8: reboot

NOTES: 

If you are going to use the Windows Hyperterminal emulation program or equivalent program to dial in with,  configure the properties to match the hardware settings. ie.,  115200, 8 data bits, none parity, 1 stop bit, hardware flow control.  Also, change the emulation in your Hypterterminal or other program properties settings to VT100.  You may need to make adjustments to the speed depending on the quality of your phone lines in your area.   The change would need to be made on both the iolanSCS and your Hyperterminal program.

When you dial and connect you will be prompted for a Login and password.  Be sure to enter the menu level user and password that you configured in the above configuration.  Only the serial ports that were configured for Console Management (reverse Telnet) will appear in the easy port selection menu.  The hotkey to exit out of a session and back to the easy port selection menu  is     ~menu     (do_not press the Enter key after ~menu otherwise you will be logged out and will need to reconnect).

Telneting to different ports

An alternative to the Easy Port selection menu,  as shown in the above configuration examples, is to manually telnet to specific ports to manage a serial device.

Method 2:    Telneting to different ports

From any network computer's command prompt,  that can reach the iolan,  telnet to a specific port to manage your serial devices. 

the command is: 

telnet  <ip address of iolan> <TCP port>  

suppose the ip address of your iolan is 192,168.1.5 and you want to manage lets say a Cisco console on port 2.

telnet  192.168.1.5  10002    (10002 is the default tcp port for port 2)
