IPS Inline Mode span configuration

In IPS V5 Inline Mode, should the second interface (where a packet comes out) of a paired interface be configured as a span port or a regular port? Where can I find more info about this? Thanks.

Need more information about your intended setup. Generally, the answer is "regular port". Your use of "span" leads me to believe you're implementing from a switch. In that case, be advised that if you're are attempting to loop back into the same switch that you originated from, you will need to have that second port in a different vlan. The sensor does not route, it is a "virtual wire"

How to tell if Active/active or Active/Standby mode is configured?

Folks:
I am still learning the output of my running config, but how do I tell if my firewall is set to Actve/Active or Active/Standby mode?
In addition, how do I tell if it uses regular or stateful failover mode?
Thank you

I wanted to provide this as well, since I found it and it also helped me answering my question.
This output shows Active/Active failover output.

Help me about CDE205 (under SE mode) - CLI configuration guide

I'm trying to looking for "CLI Configuration guide for Cisco CDE205", but only GUI guide and command reference from cisco website.
Help me if you can.
Many thanks.

The name that you type into the portal login page is the "User Name Attribute". You currently have this set to "cn", which is "xxx" (not ascii). After this name is submitted to the portal, the "User Authentication Attribute" is sent to the AD AWS. Leaving this as userPrincipalName is correct. If you would like to change what users need to type into the portal, change the "User Name Attribute". The recommended value is "sAMAccountName". This should be "user1" in your example.

I've done a hard reset of both devices and swapped them over vice-versa. The problem seems to be the network will only support a SINGLE device. In Airport Utility I can only get one of the two devices to show in the sidebar, rarely both devices are temporarily present. I've configured both to use the same network names and WPA passwords in the hope they will 'merge' together onto the same network. But one just seems to cancel out the other.
Right now I've go the old AEB plugged back into the modem and its working. But the new TC device which I've plugged into the printers wont show on the network and has the amber light flashing.

PXI first use, unable to configure/boot safe mode or RT

Hi all,
I am new to PXI controllers, i am having a few issues with a PXI controller in my university which i intend to use for my fyp project.
So we are using a PXI 1042Q chassis with a PXI 8106 embedded controller.
We started this controller for the first time and updated windows xp, we also removed labview 8.6 that came with it and installed labview 2010 with all the available drivers, softwares and liscenses..
When we start windows XP on the PXI system we can see the PXI chassis and controller identified in MAX but labview cannot find them when creating a project.. My first question concerns the reason why labview cannot identify PXI targets in a project?, could it be a missing liscence (for instance RT liscence for PXI)? or an improperly installed driver? How to check if RT liscence is missing or needed?
Due to the first problem, we tried to control the PXI remotelty from another desktop host PC where we found more problems.
1/ Can we make a connection in order to download a project from the host PC to the PXI via ETHERNET (without MXI cards) ?
2/ We tried to make the connection using ethernet but we couldnt configure the IP; when we switch to safe mode to configure, the pxi gives the following texts on screen " system error kernel 446610 LFS error not a dos disk pc-dskinit " and the system remains unconfigured with the 0.0.0.0 IP due to the failure to boot, MAX on the host PC sees the PXI as a 0.0.0.0 and changing the IP is not possible also.
To cure this issue and help the system boot, we created a desktop PC utility USB Drive in MAX (on the host PC), configured the boot devices priority on PXI and booted the PXI from the USB drive. we entered safe mode and the pxi took an IP automatically and then it displayed that the software is not present... The problem is that when we tried to install the software on the pxi using MAX on the host PC (which now sees the PXI) we got disconnected..
Note that firewall is off, the host pc has an ip in range with the one generated by the pxi, on the same subnet and has windows 7..So why are we loosing the connection in MAX after 30 seconds,, when we try to install the software on the pxi?
thank you in advance for your help.
Elias Saleh.

Dear Elias579,
Welcome you to the NI Forums!
There are basically three ways a PXI system can by characterised by the OS:
Real-Time OS running on the PXI makes it an RT Target, which then can be reached from the network by a host PC for example
"regular" Windows running on the PXI makes it a simple industrial PC, which has no real-time qualities. In this case you cannot add the controller to your project, since you are actually on the target, and whatever VIs you crate are actually on the platform already!
Hybrid systems (not all controllers are compatible with this) can run in such a way that one core runs regular Windows and an other runs an RT OS, which can communicate with each other.
Your problem is either
1.) You installed a simple windows, in which case you wont add any targets to your project since you are running every VIs on the target. The chassis works exactly like a PCIe bus slot extender, so the cards inside are the ones that matter. For example if you have a programmable FPGA PXI card, and you have LABVIEW REAL-TIME and NI-RIO driver installed, you will be able to add the card within the chassis to your project.
2.) You are just missing a driver. Since you do not have an RT OS on the PXI, you might need a suitable DAQmx for you cards.
Please to help me have more vision of your problem try to describe what cards are you using and what is actually you would like to do.
For debugging you issue, these documents might help:

https://decibel.ni.com/content/docs/DOC-16189
**EDIT:
one more thing, if you are using a regular Windows PXI, you should not seek to connect to it as an RT Target. You might try to use Remote Desktop from an another PC though.
Looking forwards to help you solve your issue,

Help with "DAC Configure for Quadrature Mode.vi" in "ni5640R Frequency Translation" Example

Hi there:
I am also using the the NI PCI-5640R and I've been "studying" the
program: "Frequency Translation", my intention is to modify it and
produce a closed-loop between I and O.
I am also interested in transferring what i am reading through the
input port, directly to the output port but filtered AND with a
phase-shift (final Objective: Q-Control).
I need to visualize the signal in the HOST, so I need both FIFOS (DMA
FIFO and Local FIFO), and the "Quadrature Mode DAC Configure"
I would like to know:
1. How can I directly transfer the data acquired through the ADC port
into the DAC? (it is unclear due to the Event structure in the
"Frequency Translation" example)
2.
How can I configure the "Quadrature Mode DAC Configure.vi" for it to
bandpass-filter the signal comming from the ADC at a given frequency
and BW, specified by the user in the HOST? I have read that it is possible to filter a signal comming to the DAC using DUCs (Digital Upconverters) Does anyone has more info about this topic?
3. Is it possible to
configure the "Quadrature Mode DAC Configure.vi" to produce a
phase-shifted signal (phase shift also specified by user in the host)
I've
been working for almost 2 months trying to program the 5640R, doing
examples, and modifying them. After playing with different examples
I've come up to the conclusion that the "Frequency Translation" example
is the one that best-suites my application. My problem now is that I
AM LOST because i need more information regarding the configuration
parameters of ALL the different VI's inside the NI-5640R VI Tree to
exploit them correctly, specially the "Quadrature Mode DAC
Configure.vi".
Can anyone please help me?
Cheers...Antonio

Hello again:
Jerry:
1. I referred to the Event structure, but in the HOST, but now, with your commentary and Philippe's explanation i've undestood better the concept.
2. Regarding the filtering, I read the datasheet of the AD6654 (DAC from "Analog Devices" which is part of the n5640r) and in pages 36 and 37, it explains with an example, the possibility of designing a Bandpass CIC Filter by changing the interpolation (or decimation) factor of the DUC (or DDC). The filter can't be fully customized (the rejection and passband are limited to an "Alias rejection Table" in page 36), but it could fit the application to filter certain frequencies.
I also tryed what you guys suggested, meaning: I designed a simple digital bandpass butterworth IIR filter in the FPGA target inside a 3rd SCTL with a faster clock (i.e. "Top level timing source") and using a 2nd Local FIFO. The filter was done with FPGA discrete delays (z^-n) departing from a "differences equation" [y(n) = x(n-1)+x(n)+0.9996858*y(n-1)]. But I have problems with the 0.99... constant which is always rounded to 1 (check the pic). I changed the variable's type and digits of precision, but it still rounds up to 1 Any suggestions?
3. I was thinking as well of shifting the phase (as Jerry said) by configurating the NCO in the DAC. Again, more information is given in AD6654's datasheet (page 35). I will quote the info:
"The phase offset register can be written with a value that is added as an offset to the phase accumulator of the NCO. This 16 bit register is interpreted as 16-bit unregistered integer. A 0x0000 in this register corresponds to a 0 radian offset and a 0xFFF corresponds to an offset of 2pi*(1 - 1/2^16) radians. This register allows multiple NCOs (multiple channels) to be sinchronized to produce complex sinusoids with a known steady phase difference:"
Any ideas of how to program this register inside the "ni5640r ADC Configure NCO" to have a fixed phase offset of 90º?
Thanx in advance for your replies
'till the next post...Antonio

Problem with configure engine in console-mode unix

i have a problem, i tried to configure an engine of enterprise in HP_UX, but the grapical-mode doesn´t work, how can i start the admin console in console-mode??? i tried ./albpmadmcenter -console but not work!!!

Hi,
You would have to install using silent mode to configure the process administrator. This option is available in Oracle BPM (OBPM). Not sure if it exists even with ALBPM 6.0.

DAC output without using DAC configure mode

Hi,
I am using NI-5640R and labview 8.2.
Is it possible to send out anything without using DAC configure (single or quadrature) mode?
Actually, what I am trying to do is to send out to DAC whatever comes in, like attachment

Data Federator authentication modes

In Data Federator (3.0 SP1 or previous), Is there any authentication mode similar to AD/LDAP in BOE?
What are the options available for dynamic logon, while connecting to a database via JDBC in the DF Data source definition screen?
Thanks
Tiji

Hi Tiji,
Connecting to Data Federator using BOE applications
In Data Federator XI 3.0 SP1 and previous versions the only way to connect to Data Federator is to provide a user name and password. Data Federator manages its own repository of users.
Using Universe Designer, you can create a Data Federator connection with two authentication modes:
- Configured Identity: the same user name and password is used for all consumers of the connection
- Database Mapping: the DBUser and DBPassword associated to the BOE user are used to connect to Data Federator.
There is no support for single sign on.
Creating a datasource using Data Federator Designer*
When you register a new datasource using Data Federator Designer you have three authentication modes supported:
- Configured Identity: the same user name and password is used to connect to the database (for all DF users).
- Principal Mapping: a mapping can be defined between a DF user and data source credentials. This is done through creating and managing "login domains".
- Caller Impersonation: the DF user and DF password is used to connect to the data source.
The Principal Mapping mode is pretty similar to the feature in BOE called Database Mapping except that you are not restricted to a single DBUser/DFPassword pair whatever data source you want to access. This is more flexible. Note that there is no UI in Administrator to manage login domains. You have to run built in stored procedures in the query tool.
Hope this helps,

How do I Configure Multiple VLANs on a SG 200-18?

I am having problems accomplishing these tasks with my new SG 200-18.
All assistance is appreciated.
I have a LinkSys WRT54G2 connected to port 1.
I would like ports 2-8 to be in one VLAN with access to the Internet and to be able to share their printers, hard drives, etc. with other computers on ports 2-8.
I would like each of ports 9-16 to be on a separate VLAN with access only to the Internet and no other ports on the switch.
I would like to be able to manage the switch from any of the ports 2-8.
After I create the VLAN 1009 (see screenshot below), port 9 can browse the Internet and cannot see the other ports on the switch which is correct.
However, ports 2-8 can no longer access the switch at 192.168.1.20 in order to manage the switch.
Please see screen shots below.
Thank you very much in advance.

Alllan,
Well first you want to make sure you are running latest firmware 1.1.1.8 I do believe
Next either console into the switch or you can turn on SSH/Telnet under Web gui (Security••àTCP/UDP services and make sure SSH/Telent is enabled)
Now we configure the switch via Cli
We need to enter global configuration mode.
Configure Terminal
(next add our vlans)
Vlan database
Vlan 10
Vlan 20
Vlan 30
Exit
(you can run show command to see your vlans)
do show vlan
(Now configure the port how you would like)
Interface GE1
Switchport mode access (this is making Gigabit port 1 an access port)
Switchport access vlan 20 (this command is changing access port vlan from 1 to 20)
(less configure a trunk port)
Interface GE2
Switchport mode trunk (this makes port 2 for trunking)
(Now less add our Vlans)
Switchport trunk native vlan 1
Switchport trunk allowed vlan add 10,20,30
Exit global configuration
(Use this command to copy your settings to startup)
Copy running-config startup-config
(Some screen shots attached)
I see you have a WRT54G router which i don't think support vlans unless you have 3rd party OS installed.
So currently is the SG300 swtich operating in layer 2 or layer 3 , guessing this is why you choose to move up to 300 series switch?
If the switch is not in layer 3 mode but in layer2 when setting it to layer3 the switch will default all pervious settings.
If the switch is set in layer 3 mode you might have forgot your default route
(Command setting default route)
configure terminal
ip route 0.0.0.0 0.0.0.0 192.168.1.1 (192.168.1.1 being address of your WRT54G)
Now you would need to set up ACL's to deny and allow what traffic you wanted to filter on the SG300
Also reading your post we would need you to call into support center SBSC @ 1-866-606-1866
This way we could get a better idea of your current configuration and assist with fixing or finding a solution for you.
you have 1 year phone support with this product
Thanks,

How to set transceiver mode to 2-wire TXRDY Auto from Visual Basic

I am using a PCMCIA-485 adapter to interface to some RS-485 sensors. The sensors are connected using a 2-wire interface. I have developed an application in Visual Basic to control the various sensors. However, the application is dependent on the PCMCIA-485 adapter's transceiver mode being configured into the "2-Wire TXRDY Auto" mode. Presently I require the user to configure the transceiver mode by opening up the advanced setting dialog within the device driver for the adapter and manually setting the transceiver mode. I would prefer to have my application take care of this directly. Unfortunately, I cannot find any references that document how to do this.
Can I use Measurement Studio Tools for
Visual Basic to control the transceiver mode of the PCMCIA-485 adapter?

Hello-
There is a registry key in Windows that can change this mode:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Serial\Parameters\Serial1000X\TransceiverMode
Try experimenting with it by hand first. It may also be necessary to reboot after changing this value.

[SOLVED]Laptop-mode-tools no cpu scaling

Hi!
After I installed laptop-mode-tools, I can't have my cpu freq scaling as I always did.
Well, I'll explain better: without laptop-mode-tools I used to set my cpu freq via /etc/rc.local, and everything was fine.
But now I need laptop-mode-tools and I have to say, everything works very well...But here comes the sun, uhm no, here comes the problem: when i plug in and out my ac cable, my frequency will stay at its lowest. The same thing happens after suspend... I can't understand...
I tried with acpid, obviously, and for example, when i plug in ac power, lcd brightness changes as expected from my config files, but cpufreq will stay just as I said.
So, here is my cpufreq-info now:

Il gestore "performance" può decidere quale velocità usare
in questo intervallo.

Ok, after i removed laptop-mode-tools and managed to have my cpu freq scaling,lcd brightness and eeepc she through rc.local and acpid events , i found that the real problem is located in ondemand governor: after suspend it stays at lowest freq possible.
If i change then my governor, with for example performance, it works, but if i change again to ondemand, it stays to its lowest...any idea?
EDIT: tried with granola and userspace governor, but nothing changes... tried on my other laptop with kernel 3.1.5-ARCH, and there everything it's ok, but i noticed i haven't acpi and acpid installed there...so may be the problem is related to them? (i use the same cpufreq driver in these laptops)
I'll try to kick out acpi and acpid and i'll make you know what happens.

Laptop-mode-tools/cpufrequtils Questions [SOLVED]

I am running a Sony Vaio VGN-FW480J and am trying to optimize these two tools to save battery life and hard drive life span. I have added @laptop-mode to my daemon array and acpi-cpufreq to modules. A few issues I immediately notice:
1) cpufreq doesn't revert back to higher frequencies if I unplug and plug power source back in (before unplugging: CPU 0 - 800 MHz, CPU 1 - 2.00 GHz; after both are 800 and won't change if I plug power source back in)
2) I believe the hard disk is actually spinning down more frequently (and fan is almost always on, even when no work is being done). Here are the relevant files/the ones that I have altered.
laptop-mode.conf
# Configuration for Laptop Mode Tools
# There is a "system" to the configuration setting names:
# CONTROL_something=0/1 Determines whether Laptop Mode Tools controls
# something
# LM_something=value Value of "something" when laptop mode is active
# NOLM_something=value Value of "something" when laptop mode is NOT
# active
# AC_something=value Value of "something" when the computer is running
# on AC power
# BATT_something=value Value of "something when the computer is running
# on battery power
# There can be combinations of LM_/NOLM_ and AC_/BATT_ prefixes, but the
# available prefixes are different for each setting. The available ones are
# documented in the manual page, laptop-mode.conf(8). If there is no LM_/
# NOLM_ in a setting name, then the value is used independently of laptop
# mode state, and similarly, if there is no AC_/BATT_, then the value is used
# independently of power state.
# Some options only work on ACPI systems. They are marked ACPI-ONLY.
# Note that this configuration file is a fragment of shell script: you
# can use all the features of the shell scripting language to achieve your
# desired configuration.
# Modules
# Laptop Mode Tools modules have separate configuration files, that can be
# found in /etc/laptop-mode/conf.d. Please look through these configuration
# files as well, there are many useful power saving tools in there!
# Enable/Disable laptop-mode-tools execution
# Set it to 0 to completely disable laptop-mode-tools from running
ENABLE_LAPTOP_MODE_TOOLS=1
# Configuration debugging
# Set this to 1 if you want to see a lot of information when you start/stop
# laptop_mode.
VERBOSE_OUTPUT=0
# Set this to 1 if you want to log messages to syslog
LOG_TO_SYSLOG=1
# Run in shell debug mode
# Enable this if you would like to execute the entire laptop-mode-tools program
# in shell debug mode. Warning: This will create a lot of text output
# If you are debugging an individual module, perhaps you would want to enable
# each module specific debug mode (available in module conf files)
DEBUG=0
# When to enable laptop mode
# "Laptop mode" is the mode in which laptop mode tools makes the computer
# consume less power. This includes the kernel "laptop_mode" feature, which
# allows your hard drives to spin down, as well as various other settings which
# can be tweaked by laptop mode tools. You can enable or disable all of these
# settings using the CONTROL_... options further down in this config file.
# Enable laptop mode when on battery power.
ENABLE_LAPTOP_MODE_ON_BATTERY=1
# Enable laptop mode when on AC power.
ENABLE_LAPTOP_MODE_ON_AC=1
# Enable laptop mode when the laptop's lid is closed, even when we're on AC
# power? (ACPI-ONLY)
ENABLE_LAPTOP_MODE_WHEN_LID_CLOSED=0
# Enable all simple zero-configuration auto modules
# This option enables all simple modules (listed below) without requiring
# the user to enable each module individually
# List of modules which can be automatically enabled with this setting are:
# ac97-powersave
# cpufreq
# dpms-standby
# eee-superhe
# ethernet
# exec-commands
# hal-polling
# hdparm
# intel-hda-powersave

# sched-smt-power-savings
# terminal-blanking
# usb-autosuspend
# wireless-ipw-power
# wireless-iwl-power

# Set this to 1 to enable all simple zero-configuration auto modules listed above.
# NOTE: You can explicitly enable/disable any of the above modules by changing their
# values in the individual settings file
ENABLE_AUTO_MODULES=1
# When to enable data loss sensitive features
# When data loss sensitive features are disabled, laptop mode tools acts as if
# laptop mode were disabled, for those features only.
# Data loss sensitive features include:
# - laptop_mode (i.e., delayed writes)
# - hard drive write cache
# All of the options that follow can be set to 0 in order to prevent laptop
# mode tools from using them to stop data loss sensitive features. Use this
# when you have a battery that reports the wrong information, that confuses
# laptop mode tools.
# Disabling data loss sensitive features is ACPI-ONLY, and it only works if
# your battery gives off frequent ACPI events to indicate a change in battery
# level.
# NOTE: If your battery does NOT give off battery events often enough, you can
# enable the battery-level-polling module to make this work. Look at the
# file /etc/laptop-mode/conf.d/battery-level-polling.conf for more information.

# Controlled hard drives and partitions
# For spinning down your hard drives, laptop mode will remount file systems and
# adjust hard drive spindown timeouts. These parameters specify which
# devices and partitions are affected by laptop mode.
# The drives that laptop mode controls.
# Separate them by a space, e.g. HD="/dev/hda /dev/hdb". The default is a
# wildcard, which will get you all your IDE and SCSI/SATA drives.
HD="/dev/[hs]d[abcdefgh]"
# The partitions (or mount points) that laptop mode controls.
# Separate the values by spaces. Use "auto" to indicate all partitions on drives

If your governor isn't listed in scaling_available_governors, it won't work. See stqn's link for info on adding governors.
stqn wrote:Edit2: oh well, scrolling a bit up, the wiki says you don't need to add governors if you're using laptop-mode-tools... I don't know.
You do need governors if you're using laptop-mode-tools, because all laptop-mode-tools does is flip between them automatically.
If you're using cpufrequtils, you'll need the userspace governor for it to work properly. I don't use cpufrequtils personally, so I'm not sure how to get it to work in conjunction with laptop-mode-tools. You may have to disable frequency scaling in laptop-mode-tools by changing CONTROL_CPU_FREQUENCY to 0 in cpufreq.conf
Edit - now that I think about it, maybe laptop-mode-tools and cpufrequtils know how to load the modules themselves automatically. I guess try it and see if they can. You can check which governor is in use with:
$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
You can also manually change governors by running (as root):
# echo "conservative" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
Of course, substitue the governor you want.
