PPPoE - max. quantity of users on single Ethernet segment

Hi,
I'm wonder if anybody has experience in case of connecting huge quantity of PC-users on single ethernet segment (for example: one VLAN 802.1q) with PPPoE. How many users can works on the same VLAN ?
I know that differents PPPoE aggregators has each own differents limitations for maximum value of PPPoE sessions (for example: Cisco 6400 NRP-1: 2000, Cisco 6400 NRP-2: 4000).
I need to connect 3000-4000 users to PPPoE aggregator. Do I have to divide them to 4-5 (or more?) VLAN's ? Or can I make them working in one VLAN ?
Best Regards,
Marcin

Marcin,
The limitation is for the device as a whole. It comes down to the memory and CPU.
It doesn't matter how many users you split off into seperate VLANs. If the router supports 2000 connections then your going to get 2000 regardless of the number of vlans configured.

    Appreciate your support and if possible , how to do this?

    If you want to work with Mac OS X, you need one computer per simultaneous user.
    What you are describing, " Multiple simultaneous logins to a single computer" is not avialable on a regular Mac of any description, unless you decide to use Unix tools instead of Mac OS X.
    Server will happily store files for many, many users and provide them to multiple (up to hundreds) of computers at "near hard Drive" speeds over Gigabit Ethernet. It can make the File Sharing part easy.

  • How to moniter the max quantity of used dialog work process in SAP system

    Dear Gurus,
    The quantity of Dia Work Process(DWP) of APP1 is: 16 (rdisp/wp_no_dia=16)
    The quantity of Dia Work Process(DWP) of APP2 is: 16 (rdisp/wp_no_dia=16)
    The quantity of Dia Work Process(DWP) of APP3 is: 20 (rdisp/wp_no_dia=20)
    The quantity of Dia Work Process(DWP) of APP4 is: 20 (rdisp/wp_no_dia=20)
    So the quantity of DWP in our SAP system is: 72 (=161620+20).
    We have 75 dialog users and many RFC callings via JCO method from J2EE system.
    I'm afriad the 72 DWPs will be run out of use someday.
    So I want to moniter the max quantity of used DWP every per hour to prevent the situation I mentioned above.
    Could you give me some suggestions?
    Thank you very much..
    Jason

    Hi Olivier,
      I really appreciate your help. You told me a very useful clew!
      As the method you told me, I have some questions:
      (a3) Do you restart your 'CI + 6 DIA' separately every week? Why did you do that?
      (a4) How to calculate 'CPU intensive time'?  For example, App server 'APS' was restarted on 8-10-2011 and stopped on 8-20-2011.
    There was a DWP(PID 557550) was created and activated on APS during this period(10 days). So If I add up each 'cpu time' of the task
    which 557550 executed, I can get the 'CPU intensive time' of 557550 (dispalyed in SM50). Right?
        In other words:
           DWP(PID 557550) finished task1: cpu time = 5ms  8-10-2011
           DWP(PID 557550) finished task2: cpu time = 4ms 
           DWP(PID 557550) finished task3: cpu time = 6ms  8-20-2011
         So the 'CPU intensive time'(Between 8-10-2011 and 8-20-2011) of DWP(PID 557550) is: 15ms (5ms4ms6ms). Right?
      (a5)Can we moniter the 'CPU intensive time' of DWPs in CCMS automatically? (I want to prevent the situation: The DWPs in our entire ECC are occupied.)
    Thank you!
                                                                                    Jason

  • Max quantity of material at sales order

    Dear gurus,
    I need to set a max quantity of materials when creating a sales order, in order a user can not add more than permitted amounts of material.

    I need to set a max quantity of materials when creating a sales order, in order a user can not add more than permitted amounts of material.
    I can't think of any business situation where the requirement makes sense.
    Your users should know what quantity they should enter or have be disciplined for sabotage!!
    Validations are useful to avoid mistakes, but is that really a mistake?
    IMHO you should first challenge the requirement to check if makes sense.

  • Remote Desktop Connection with single Ethernet cable

    Hi,
    I'd like to be able to use Microsoft's Remote Desktop Connection app to connect to one of my XP machines with my PowerBook. I can do this when everything is running on my home LAN, but I'd like to be able to connect with just a single Ethernet cable connected from my PowerBook's network port to the network card of the XP machine. This would allow me to use the PowerBook as a monitor when I bring the XP machine offsite to run tests (I'm a computer technician). I've played with the Network settings in the System Preferences, but things that would seem to me to work don't work. Any suggestions would be appreciated.
    Thanks,
    Ken

    When you're on the road, and these are the only machines connected to each other, you will either need to configure them to have static IP's in the same subnet
    192.168.0.2 and 192.168.0.3
    255.255.255.0
    no gateway/router IP required.
    THey'll need to be in the same workgroup (but you probably have that already)
    ...or...
    Configure the XP machine to be the DHCP server, and the mac to get IP from XP.
    (first option is probably better.)
    Might need a crossover cable. Might not.

  • Max no. of users connections in essbase

    Hi All,
    How can i find what is the max. no. of users connections is allowed for essbase. If there is some setting in EAS console or we can define it through MAXL. We are using very old version (version 6- using ESSCMD commands). We have already provided access to about 475 users. 200 more users are waiting for access.
    Thanks,
    Anchit

    Herewith the relevant parameter you can define in your ESSBASE.CFG - it should answer your question:
    MAXLOGINS
    Sets a limit on the number of user sessions that can be connected to the Essbase Server at any one time.
    Syntax
    MAXLOGINS n
    n Any integer from 1000 to 1048575 is valid. The default value is 10000.
    Description
    This setting limits the maximum number of user sessions allowed to connect to the Essbase Server at any one time. This number includes multiple instances of the same user.
    You may wish to adjust the value of MAXLOGINS to match computer resources, or to more closely manage concurrent ports and user sessions. A concurrent port is used for each unique combination of client machine, Essbase Server and login name. For example, the same user > with five open Excel worksheets connected to the same Essbase Server use one port, but five sessions.
    Notes
    Increasing the value of MAXLOGINS increases memory use approximately 6 bytes per user session.
    If the setting is less than the minimum value, 1000, the value is assumed to be 1000.
    Example
    MAXLOGINS 50000
    increases the maximum number of simultaneous logins possible, from the default of 10000 to 50000. > Kind regards

  • PP: Default BOM base quantity by user ID

    Hi Experts,
    We want to default BOM base quantity by user ID when they create new BOM by CS01.
    We set a new parameter ID for BOM base quantity similar as SAP standard parameter ID for BOM usage, and assigned new parameter ID to BOM base quantity data element BASMN.
    User could change their own data from the default parameter ID tab to fill the default BOM Base quantity.
    However, it is still required to add the parameter ID into the programs which is created BOM to achieve the final result.
    Anyone has the same requirement? Please suggest.
    Thanks.

    Hi Qiuyan,
    header quantity is defaulted reading TCS03, if it's always the same you can change it in view V_TCS03_V. Otherwise I suggest an enhancement IN LCSDIFHX FORM TCS03_LESEN.

  • There is any restriction on max quantity of queues?

    Hi, i work in a large gps tracking company.
    We are rebuilding our software and looking into msmq to storage the coordinates to be processed.
    The problem is, each tracker unit need to be isolated in on queue and we have 500k+ trackers online, so, we need tons of queues. 
    Im worried about performance. 
    Does msmq has any restriction on max quantity of queues?
    How much memory each queue consume when they are idle and when have connections? (beanstalk +/- 300bytes, rabbitmq 30kb,...)
    There is any way to use msmq in cluster?
    Didnt found anything on msdn about this.
    Thanks!

    By default value is 4MB for each queue and 1GB for the entire queue.  The queue quota can be changed using MQSetQueueProperties()
    with PropId PROPID_Q_QUOTA

  • Can't enable root user in single user mode

    hey, im having a problem. I cant enable the root user in single user mode. This is what I do:
    1.boot in single user mode
    2.I run the command /sbin/fsck -fy
    3.I run the command /sbin/mount -uw /
    4.I run the command passwd
    5.I type the password and then I retype it, but it gives me an error saying passwd: cant change password for root the account is not enabled (thats not exactly what it said, but you get the point)
    this worked in leopard, why dosent it work now? can someone give me an alternative way or tell me what im doing wrong?
    P.S. give me an actual answer not a why enable root? and I dont want to use directory utility.

    The command is wrong man. Do the following:
    Boot into S.U. Mode (Cmd+S).
    once the terminal prompt opens, type the following:
    mount -uw / ("mount"+space+"-uw"+space+slash)
    launchctl load /System/Library/LaunchDaemons/com.apple.opendirectoryd.plist
    passwd root
    (after you press enter it will ask the password for the root user. Type it, even if it won't show any character. Then type again to confirm. Once you had finished type: exit).
    Test it and post the results.

  • We have two company user,till now there are using same URL.but they wanted to access particular URL to related company user in single server

    Hi Experts,
    We have two company user,till now there are using same URL.but they wanted to access particular URL to related company user in single server.
    As per my knowledge ,it is possible through create new aliases with different URLs in network.
    But i dont how to create. Please help on this.
    Thanks in advance.
    Regards,
    Prasad

    Hi Prasad,
    Please explain in clear english as to what is your requirement. I got lost after "two company user" . I suppose it means there are users from two separate company: A and B. They were using same portal till now: http://commonportal:50000/irj/portal.
    Now they need different urls - specific for each company say companyAportal.com and companyBportal.com. But still the same old common portal in the end.
    If that's your requirement please search the forum with correct terms, else "Google".
    Thanks,

  • Min and Max Quantity on Retail Article

    Hi Experts,
    In IS-Retail, in the sales view of the article master record there are two fields: Min Delivery Qty and Max Delivery Qty.
    If anyone has had experience in using this field, I would appreciate if they can explain to me how these fields work.
    I would like the system to provide a warning/error message if the order entry person enters a quantity on the sales order item that is less than the Min Qty or more than the Max Qty specified on the Article record.
    I have tried to test this but I was not able to get the system to issue the warning/error message.
    If someone could explain to me how these fields work, and how I could accomplish the min/max quantity restrictions that my client would like to enforce, I would greatly appreciate it.
    Thanks,

  • Can we map three BPC users with single domain user

    Hi..
    When we map the three BPC users in the ABAP server in the program UJA3_WRITE_SYS_USERS with domain user,can we map with only one domain user for all three BPC users or we have to use three different domain users to map the three BPC users?
    Please do reply
    Thanks
    Bobby

    yep
    u can map three bpc user with single domain user.
    but domain user must have management roles.
