How to connect to lan console

Hi all,

I have a N4000 with several lan cards. one of them is lan console, how do I connect to it to get the GSP menu?

telnet does not work.

2. how do I find out which IP address belongs to the console? Do I need to actually connect a dumb terminal to the port to find out the ip address?

thanks
Kathy

Re: How to connect to lan console

You can use a dumb terminal (lap top with hyper Terminal) to connect to it and set its IP address. After that, you can telnet to it.

hi,

the GSP have also a serial console connect it with putty ( they have alredy a serial port support ) and set the GSP/LAN ip.

theme i the lan is configured you should be able to connect from lan.

Re: How to connect to lan console

hi,

this are the commands for GSP :

GSP - Guardian Service Processor.
BIOS level command, accessible even when machine is
in Power Off state.

Use serial console or LAN console,
hit ^B
default is unsecured so just press enter for username and
password to gain GSP> prompt access.
Accessible all the time, it will not cause any interruption of running system.
If machine gets into boot process, user session to GSP will end.

HE = help, LI in there list commands:

==== GSP Help ============================================(Administrator)===
AC : Alert display Configuration PC : Remote Power Control
AR : Automatic System Restart config. PG : PaGing parameter setup
CA : Configure asynch/serial ports PS : Power management module Status
CL : Console Log- view console history RS : Reset System through RST signal
CO : COnsole- return to console mode SDM : Set Display Mode (hex or text)
CSP : Connect to remote Service Proc. SE : SEssion- log into the system
DC : Default Configuration SL : Show Logs (chassis code buffer)
DI : DIsconnect remote or LAN console SO : Security options & access control
EL : Enable/disable LAN access SS : System Status of proc. modules
ER : Enable/disable Remote/modem TC : Reset via Transfer of Control
HE : Display HElp for menu or command TE : TEll- send a msg. to other users
IT : Inactivity Timeout settings VFP : Virtual Front Panel display
LC : LAN configuration WHO : Display connected GSP users
LS : LAN Status XD : Diagnostics and/or Reset of GSP
MR : Modem Reset XU : Upgrade the GSP Firmware
MS : Modem Status

-0-

CO return to console mode, exit GSP.
contrast to exit, which will logoff a telnet to the LAN console session.
LS, LC Show and configure LAN console settings (IP, hostname, etc),
extremely useful, make sure to configure it!
TC Send signal to OS, force it to do a core dump and reboot.
Probably similar to Sun OBP sync cmd.
RS Harshes restart of system, no OS interaction, no core.
SUN OBM reset.
PC allow turning machine on/off. Can perform power cycle.
GSP and LAN console will remain usable after power off.
Contrast to SUN LOM and AIX serial access,
just need to have power fed into machine.
PS Monitor status of power supply, fan, etc.

SL Show log, GSP level logging, with timestamp in UTC/GMT.
Use this command to clear attention light.
CL Show text message that has been displayed to the console.

VFP display a virtual front panel, a mirror of the LED in front of machine.

>I do have IP address on all my 4 lan cards

If you telnet to each, which one looks like the console and honors control-B?

Re: How to connect to lan console

none of them work with the GSP id and password. the one ip that i think is the console does this:

# telnet xxxxxxxxx
Trying...
Connected to xxxxxxxx.
Escape character is '^]'.

Sorry, LAN Console access is currently disabled.
Local flow control off
Connection closed by foreign host.

Try ssh, whether there is luck.

No luck, with ssh.

I'm thinking the lan console is disabled and i have to connect a dumb terminal to the port directly and see what's going on. like one the previous posts said.

Re: How to connect to lan console

OK, now I connected a CRT to the console card, and I got to MP and then to CM. I checked the lan config and the ip address for the lan console is wrong. if anyone has a link to MP manual I would really appreciate it.

Re: How to connect to lan console

Connect via serial line or web browser and check

EL : Enable/disable LAN access

Most likely telnet is disabled.

Hope this helps!

Torsten.
