SG500 - DHCP server does not assign predefined static IP addresses to hosts

hi guys
I upgraded my SG500 switch firmware to 1.3.0.59, since there is a new functionality DHCP server v.4
well I must say I came accross the issue I cannot solve. DHCP server assign dynamic address - no hassles.
troubles start with static IP hosts.
I defined a couple of hosts with static address within the correct subnet. I tried with hardware address and client identifiers. no luck. my switch does not assign the IP address I assigned to the suitable mac address. to define it I use both CLI & Web.
no of them works. any idea ?
below the cut from my config:
ip dhcp pool host HP-Ellite
address 10.10.11.7 255.255.255.0 client-identifier 01:d8:d3:85:cf:09:72
client-name HP-Ellite
default-router 10.10.11.1
exit
ip dhcp pool host VAIO-Z
address 10.10.14.108 255.255.255.0 hardware-address 54:53:ed:1c:a1:46
default-router 10.10.14.1
exit

Tom, thnkas for a quick reply...
look, usually it is pretty easy to manage an issue with so precise instructions. but this particular time it is not.
as I understood the "dhcp option 61" is nothing more than "00" which go before pure hardware address.
so, coming back to my example from the first post
with this configuration, my switch assigns 169.254.110.130 255.255.0.0 address
ip dhcp pool host HP-Ellite
address 10.10.11.112 255.255.255.0 client-identifier 01:d8:d3:85:cf:09:72
client-name HP-Ellite
default-router 10.10.11.1
exit
with that configuration, my switch assigns 10.10.11.11 255.255.255.0 address
ip dhcp pool host HP-Ellite
address 10.10.11.112 255.255.255.0 client-identifier 00:d8:d3:85:cf:09:72
client-name HP-Ellite
default-router 10.10.11.1
exit
otherwords "00" does not work as explained (unless I misunderstood the meaing of dhcp option 61). my switch assigns first available dynamic IP address. atlhough the arp table is cleared, dynamic address table is cleared as well. swtich is rebooted, host is rebooted
once I change hardware address prefix to "01", my host asign itself 169.xxx.xxx.xxx adress.

  • DHCP server does not assign IP addresses SG500 firmware 1.3.5

    good day collegues
    has any of you come across the following issue:
    my switch (after upgrading to the newest firmware 1.3.5) does not assign IP addresses to some of the hosts.
    after a couple of hours I managed (do not even how) to force my switch to assign IP addresses only to some of the hosts.
    still some of them cannot get the IP address and remain with "funny" IP address like i.e. 169.254.100.100
    additional info
    1. if I boot my switch with the previous version of firmware (1.3.0.6) everything is OK. all my hosts get correct IP addresess
    2. the hosts which do not get IP address were perviously entered in stat host table - now removed, ARP cleared, etc, everything many many times rebooted.
    I ran out of ideas, could you pleae give me some hints ?

    Hi Andbor, please make a backup config of your file, factory reset the switch.
    After this, manually configure a DHCP scope without any other configuration.
    Just something simple like this
    ip dhcp pool network GUESTS
    address low 10.10.14.1 high 10.10.14.254 255.255.255.0
    lease infinite

    default-router 10.10.14.254
    dns-server 10.10.10.1 62.233.233.233
    Verify your machine receive IP address with no other configuration.
    In some ways, I'm afraid some of your connections black listed due to the arp inspection.

  • Problem sending E mails advises :server does not recognise my E Mail address"

    When trying to send an E mail from my I Pad within reach of of my wifi router the mail is rejected by saying the server does not recognise my E mail address I have not experienced this before & would appreciate any advice to remedy the problem.Also the mail is sent to my SENT BOX & I cannot do anything with it other than delete.

    it seems that after a upgrade these days you get problems ???
    Sadly so far too often.
    Since it's on more than one, I think you should contact BT, there are several 5.7.1 meanings...

  • DHCP Server does not work after Exporting and Importing Using Netsh Command

    Hello Friends :
    I had two dhcp servers in windows server 2003 server , I have upgraded one of them to windows server 2008 32 bit and again i installed a windows server 2008 R2 as an additional Domain Controller , the last scenario was like this :
    srv-1 : windows server 2003 + DHCP = working with no problem
    srv-2 : windows server 2003 + DC + DHCP = Worked without problem
    srv-3 : windows server 2008 R2 + DC = worked without any problems
    I exported the DHCP server configuration on the srv-2 using netsh dhcp server export and Imported them to srv-3 using the
    netsh dhcp server import command , the command completed successfully and i can see all of the scopes without any problems and errors , i have authorized the new server without any problem , all scopes are activated without any problem so i
    disabled the srv-2 DHCP service and unauthorized it from active directory , the problem is that the new server semms that does not lease any address to clients !!!
    1- I have authorized it
    2- I used Rogue Checker tool in client computers they see authorized server without any problems
    3- The same tool in workgroup only shows srv-1 as the DHCP server and does not see other DHCP servers
    4- Bindings are OK and DHCP servers only have one NIC installed on them
    What can i do to make sure my srv-3 DHCP server will work on the network ?
    thanks ...
    MIMO

    Are the clients on another network so you need to configure a DHCP relay agent?
    If you load up perfmon on the dhcp server and remove all counters and then add DHCP counters. Do you see any dhcprequests when you reboot your dhcp clients? This will determine if your server actually receives any dhcp requests.
    Have you check event viewer for any warnings or errors?
    And the classic one restarted the dhcp server service (or reboot)?

  • Yosemite DHCP Server does not die !

    I run a small office where the MacOSX (Yosemite) server does mail, dns, etc. but not DHCP - the addresses are handed and managed by the router, a very good and sophisticated one (Miktrotik).
    It all worked fine until at some point my partner by mistake enabled the DHCP service on the OS X Server. Shortly he disabled it again (turned it off in the admin application). However even though it shows to be "off" and "disabled", the **** thing keeps answering DHCP requests and giving out addresses.
    Checking the logs I can clearly see bootpd is answering requests - so I killed it. The server resucitated it and kept answering requests.
    I've tried restarting, turning the service on and off again, everything to no avail.
    How could I disable it for good?

    You could briefly enable it, then edit the DHCP settings to disable the network interface it is listening on and save that setting, then delete the zone and again save it, and then disable it again. It should then have no settings to give out even if still running.
    I presume you have tried rebooting the server?
    You could also try the following in Terminal.app
    sudo /bin/launchctl unload -w /System/Library/LaunchDaemons/bootps.plist
    You could also check that the /System/Library/LaunchDaemons/bootps.plist file contains a value for the Disabled key of true, i.e. yes it is disabled.

  • Not Able To Assign A Static IP Address To Windows 2008 64 bit Server

    Hello Experts,
    I've been trying to assign a static IP address to Windows 2008 R2 Server Virtual Box image. As soon as I assign static IP address to the image, either it hangs or says "Unidentified network".
    I'm 100% sure that I'm using correct IP address, Gateway, Subnet mask and DNS Server details. If I use same settings on other linux virtual box, it is able get that static ip address. The issue is only with Windows 2008 image.
    Here few more inputs that may help:
    - Windows 2008 image has "Bridge" adapter.
    - Host system is connected to corporate network via wired connection and NOT on VPN.
    - If I use "Obtain IP address automatically" setting, then it is able to get a dynamic IP address and internet is working fine.
    Questions:
    1. Has anyone seen this issue before ?
    2. Do I need to do any additional configuration on Windows 2008 server ?
    Thanks,
    GK

    Hi,
    Method 1: Uninstall and reinstall network drivers.
    Method 2: If you have any anti-virus software, disable them.
    You can also try set a static IP via neetsh commend.

  • DHCP: force router to assign predefined infinite DHCP address

    Does anyone know if its possible to force a router only to assign an infinite DHCP address when a client connect to the network?
    In the configuration (2911 router) there is an DHCP server configured which assigns specific IP addresses to certain mac addresses (in this example to Client1 with mac address 00aa.00bb.00cc.ab). Due to security reasons I want to avoid that a user of a device can manually set a different ip address on his device and still be able to use/connect to the router (so far this is possible). 
    DHCP config is:
    ip dhcp pool data
     network 192.168.2.0 255.255.255.0
     default-router 192.168.2.1 
     dns-server 10.10.10.1 
    ip dhcp pool Client1
     host 192.168.2.10 255.255.255.0
     client-identifier 00aa.00bb.00cc.ab
     dns-server 10.10.10.1 
     default-router 192.168.2.1 
    Thanks, Frank

    you can use IP source guard feature along with DHCP snooping  to mitigate such a security threat.
    Ip source guard uses DHCP snooping database to test that if incoming packet's source ip is assigned by dhcp server or not, in case of illegal source ip address, the packet will be dropped.

  • DHCP client does not work poperly after systemd and Gnome 3.6 upgrade

    Upgraded my system today from Gnome 3.4 to 3.6 (and systemd was updated as well), and since then acquiring an IP address using DHCP does not work anymore.
    I am using IPv4 only internally, but neither dhclient or dhcpcd manages to get an IPv4 address.
    It seems like IPv6 is priority one, and beacuse there is no IPv6 DHCP server available NetworkManager aborts the whole setup process.
    To make sure that IPv6 should not be considered, I have changed "method" in NetworkManager to "Ignore" for IPv6.
    I have also tried to downgrade NM to 0.9.6.0 from 0.9.6.4 (since that version works on another, not upgraded, machine), without any result.
    Also switched dhclient to dhcpcd, without any result.
    The machine is a "pure" systemd machine.
    DHCP works for other devices in the network.
    Versions:
    systemd 195-2
    NetworkManager 0.9.6.4
    isc-dhclient-4.2.3-P2
    I have no issues on a system where following versions are running:
    systemd 189-4
    NetworkManager 0.9.6.0
    dhcpcd 5.6.2
    Log: http://pastebin.com/2wMC0JLe

    Think I have identified the issue now.
    Neither dhcpcd or dhclient is sending the host name properly to the DHCP server anymore. I had an IP address reserved in the DHCP server for my host and after deleting this reservation my host is able to acquire an IP (dynamic) address. The reserved static address could never be acquired.
    Conclusion: dhclient and dhcpcd is not sending the host name as before, causing the DHCP server to get stuck (while waiting for the host name) whenever a NIC with a reserved IP address is requesting an IP address.
    Downgrading the dhcp clients has not yet worked, so there might be some underlying component that is causing the problem. ath5k? systemd?

  • The security database on the server does not have a computer account for this workstation trust relationship

    When I try to log on to my DC it says "The security database on the server does not have a computer account for this workstation trust relationship". It won't let me log on. I installed another server server 2012r2  (its virtual )
    and I can get to ADSI edit. 
    I think what happened was I had a pc that could not connect without unplugging the network cable. So I found this fix 
    FIX: “The security database on the server does not have a computer account for this workstation trust relationship”2032011
    I’ve seen a lot of solutions, or suggestions rather, with regard to the error in the title of this post.  In my experience, the problem can almost always be resolved without extra domain add/removes and reboots, which is the most prevalent solution I have
    seen around.  Usually, this issue is due to a mismatch between attributes of the computer account in Active Directory and those values on the system itself.  Here are the steps I take to fix this issue when it crops up:
    Open up Active Directory Users & Computers pointed to the domain the computer account resides in
    From the “View” pull-down menu, make sure that “Advanced Features” is checked
    Navigate to the part of your organizational unit (OU) structure where the computer account for this server resides
    Open the Properties for the computer object
    Choose the “Attribute Editor” tab on the Properties dialog box
    Check the Attributes dNSHostName & servicePrincipalName – anywhere that a fully qualified hostname is specified (e.g. myserver.mydomainname.com), make sure that the entry matches the hostname
    you have configured when you go here on your server: Start -> Computer -> Right-Click, Properties -> Change Settings (under “Computer name, domain… settings”) -> Full Computer Name
    As an example, for a fictitious W2K8 R2 server whose Full Computer Name is “srv1.mydomainname.com”, these attribute/value pairs should be in Active Directory:
    dNSHostName:
    srv1.mydomainname.com
    servicePrincipalName:
    HOST/SRV1
    HOST/srv1.mydomainname.com
    RestrictedKrbHost/SRV1
    RestrictedKrbHost/srv1.mydomainname.com
    TERMSRV/SRV1
    TERMSRV/srv1.mydomainname.com"
    Not reading it carefully I add a computer with the same name as the pc having the issue and followed the above. The problem is that I did not notice that the spn did not want the name of my server (serv1) but the name of the trouble
    pc.

  • Server does not create ois ?

    Hi folks !
    At first I wanted to send some Strings via the Client to the Server and print them onto the screen. On a specific String "antwort" I would like to send an Object k from the Server to the Client and prove on the Client the correctness of the object by reading the attribute set on the serverside before sending.
    But somehow the server does not create the ObjectInputStreams and I don�t know why.
    That�s the code:
    // Server:
    public class Server {
    public Server() {
    try{
    String input = new String();
    ServerSocket sock = new ServerSocket(16348);
    Socket socket = sock.accept();
    System.out.println("socket"); // this line is printed on connection
    ObjectInputStream sockin = new ObjectInputStream(socket.getInputStream());
    System.out.println("objectinputstream"); // but this one never appears
    ObjectOutputStream sockout = new ObjectOutputStream(socket.getOutputStream());
    Kunde k = new Kunde();
    k.setNummer(13);
    while(!input.equals("Ende")){
    input = sockin.readObject().toString();
    if(input.equals("antwort")){
    sockout.writeObject(k);
    sockout.flush();
    sockout.reset();
    System.out.println(input);
    socket.close();
    catch(Exception e){
    public static void main(String[] args) {
    // TODO code application logic here
    new Server();
    // The Client
    public class Client {
    public Client() {
    try{
    Socket sock = new Socket("localhost",16348);
    // System.out.println(sock.isOutputShutdown());
    sock.setSoTimeout(5000);
    System.out.println("socket hergestellt");
    ObjectInputStream sockin = new ObjectInputStream(sock.getInputStream());
    System.out.println("sockin");
    ObjectOutputStream sockout = new ObjectOutputStream(sock.getOutputStream());
    System.out.println("sockout");
    String eing = "";
    System.out.println("vor while");
    while(!eing.equals("close")){
    eing = erwarteEingabe();
    System.out.println("Sende:"+eing);
    if(eing.equals("antwort")){
    sockout.writeObject(eing);
    Kunde k = (Kunde)sockin.readObject();
    System.out.println("Nummer des Kunden: "+k.getNr());
    else{
    sockout.writeObject(eing);
    sockout.flush();
    sockout.reset();
    catch(Exception e){
    System.out.println(e);
    public static void main(String[] args) {
    // TODO code application logic here
    new Client();
    private String erwarteEingabe(){
    String eing = "";
    System.out.println("nehme Eing entgegen");
    try{
    BufferedReader b = new BufferedReader(new InputStreamReader(System.in));
    return b.readLine();
    catch(Exception e){
    System.out.println(e);
    return "";
    }

    When you create an ObjectInputStream it tries to read the object stream header from the underlaying stream. In this case both your server and client are waiting for the other one to send the header before they can continue. This problem can be avoided by simply creating the object output streams first:ObjectOutputStream sockout = new ObjectOutputStream(socket.getOutputStream());
    ObjectInputStream sockin = new ObjectInputStream(socket.getInputStream());

    If above sql returns a row where STARTAPPSERVER=1, then the user <OPRID> can start the application server.

  • DHCP Server is not passing out DHCP Leases

    I can't seem to figure out why DHCP server is not passing out DHCP lease a client?
    Also I can't seem to figure out why NVI0 interface is UP? I have setup another box similarly and NVI0 is down on that and the DHCP server is working fine on that too. Strange!

    Hi Jennifer,
    I have gotten it resolved. Per your suggestion, I have turned on debug ip dhcp events and found that POOL EMPTY message. After little research, I found out that I have made a mistake in my excluded-address range.
    I have had it as 
    ip dhcp excluded-address 192.168.1.1 192.168.100.101
    It should have been
    ip dhcp excluded-address 192.168.1.1 192.168.1.101.
    It was a typo.
    Thank you for the suggestion.

  • Problems with Tomcat Server : Does not respond (Sometimes) - Plz Need Help

    I have a web application running on Tomcat 4.1.31. (SUN/Solaris)
    Clients access through iPlanet Web Proxy (SUN/Solaris).
    Theres a class that build a generic form (it return html codes) then it's affected in the JSP page :
    MyClass class = new MyClass();
    <%= class.getHtmlCode() %>
    the size of the form is variable (100Ko to 1,5Mo)
    When i m using the proxy, sometimes the server does not respond when he do the affectation <%= class.getHtmlCode() %>.
    If i call the page without proxy it work.
    The problem seem not depending of the size of the form. Without proxy it always work. And with proxy sometimes the server does not work.
    Please need help

    This happens on every machine i have tested. If i hold down the Ctrl+Alt keys, then the imaging menu appears, i can select maintenance and the client will pull down the initrd, etc.. fine.
    if i disable the IPHelper, move the client to the same VLAN as the server, then the whole process works perfectly.
    not sure where to go from here.
    help please ;)

    Hi Leon,
    If you are getting the ZENworks menu when holding down the Ctrl-Alt keys, PXE/PDHCP seems to be doing the right thing. Routing issues also don't seem the case as you can pull down the first PXE boot files....
    The server running PXE, I assume it also runs the TFTP and Imaging services?
    These services are also running a recent version of Zen 7 (IR3/IR4)? A little more info on these components and what server they are on would be good :)
    Cheers,

  • I bought a new imac running Loin and Office 2011. The server we use to access emails runs exchange 2003 and my IT person says the imac is not compatible with the server. The server does not want to let me access using any email software.

    I bought a new imac running Loin with Office 2011. I am the only mac in the office and the Server we use to access emails runs exchange 2003 and my IT person says the imac is not compatible with the server. The server does not want to let me access using any email software other than webmail access through our website. It looks as though 2011 is not compatible with 2003 per some searches online, but what are some options I have to gain full access again? I purchased parallels in hopes that this my help and I am able to use remote desktop connection to log on to server but can not drag and drop files I need. There is a shared drive on that Server we all use to exchange files.
    The two main issues are gaining access to my email again and ability to drag and drop files from mac to pc. I hope this is enough info to get some solutions.
    PS - IT person says my iMac's IP is what his server does not understand so that is why I can not login.

    Office 2011 is not compatbile with Exchange 2003.
    I suggest you post further Office related questions on Microsoft's own forums for their Mac software:
