Get a next available external network IP

Hello

I am trying to automate the deployment of nested environments that require external network connections. I'm looking for a way to determine the next free IP available from a given external networks IP pool. I can get the list of IP addresses in the pool, the number used and total number total free but have been unable to find a method to show what is free then.

There must be a way to get this information that the deployment of a new edge on an external network takes the next free IP available.

Someone at - it chance with that?

Posted this on my Blog, but here is the final code, application that I came that works for my application.

  • Get the assignment of the IP to an external network

    Hello

    as mentioned above, I want the query wo assignment of IP to a given external network organization.

    As a goal, I want to know, what external IP number (of a certain external network) is attributed to each organization.

    Is it possible to do this via the REST API?

    Thanks in advance!

    It was something, that I recently looked into after that a colleague has asked about it.

    The eaiest IMHO is to use the vCloud API Query Service (http://blogs.vmware.com/vsphere/2012/04/quickly-finding-objects-using-the-vcloud-api-query-service.html)

    Here is a screenshot of an external network called "Ext-network-1" for a VCD 5.1 deployment

    Step 1 - make a GET to the following URL: https://[VCD - IP] / api / query? type = externalNetwork

    Step 2 - this should return a list of NetworkRecords that will be your external networks available, here is a screenshot using FF RestClient

    Step 3 - Once you have identified the property "name" of your external network, you will need to do a GET on it's HREF

    Step 4 - from here you can see the current range of intellectual property as well as the allocated IP addresses

    If you want more details on IP addresses allocated, you will see in the 'link' there is /allocatedAddresses you can do a GET on this URL, which will give you more details

  • Assignment of IP with vCAC external network profile

    I joined vCAC and NSX, and note that the Service Edge router that gets deployed on a blueprint multi-machine receives 2 IP addresses on its unique "uplink" profile external network interface.  Here is my setup and what is happening.  Any help to understand why this would be useful.  Not a huge deal because it is a learning laboratory, but when I go to implement it in a production environment, I need to know if this is expected behavior, or if something is wrong because it effectively reduces the number of possible networks to deploy-able by half.  Again, not a big problem as this "transport network" (the section between the Edge Gateway manually deployed and dynamic Service Edge routers) will exist entirely in the vSphere environment and can be as big as a class A network, if necessary, it is however a huge waste of space IP I want to solve it if possible.

    Topology:

    I have a NSX Edge and the virtual wire (switch NSX L2) already deployed in the environment.  Within vCAC I have:

    -a reserve related to the dvPortGroup created by the NSX L2 switch

    -an external network profile that is used to configure the port to uplink of dynamically deployed NSX routers edge of Service to connect to the LAN segment between the dynamic ESR and the switch of NSX Edge/L2, already deployed

    -a profile of NAT network 1 number which is used to configure the virtual machines deployed from vCAC plans

    -a vSphere vCAC VM blueprint pointing to a snapshot of a virtual computer within the environment vSphere (linked clone deployment)

    -a plan of multi-machine vCAC which contains the above plan and assigns a network interface to the virtual machine and using the profile of network NAT 1 to configure the IP settings on the virtual machine.  MM master plan contains only a single VM in order to test the dynamic creation of network and IP assignment features/integration between vCAC and NSX.

    Topology resulting, once the virtual computer is deployed:

    Edge (deployed manually) NSX gateway

    v

    v

    NSX L2 Switch/Virtual Wire (deployed manually

    v

    v

    NSX edge router Service (deployed as part of the deployment of the vCAC action plan)

    v

    v

    VM (deployed as part of the deployment of the vCAC action plan)

    In theory what needs to happen is that when I ask a resource of the Architecture SDSE MM:

    1. the ESR is deployed with 2 interfaces: 1 for the external network configured with an IP address available on the corresponding subnet and 1 for internal NAT network configured with the IP address of the default gateway is configured in the profile of NAT network.

    2 NAT rules and treatment of traffic are automatically configured in the ESR

    3. the virtual computer is deployed and configured with a NETWORK adapter with the configurations appropriate IP such as specified in the profile of NAT network.


    What is actually happening:
    1. the ESR gets deployed with 2 network cards; 1 NETWORK card for uplink to the external network, which gets 2 IP addresses on the subnet (instead of 1) 13 and 1 NIC for the default gateway of the NAT had network configured with the IP address of the NAT network default gateway.  Steps 2 and 3 still occur.

    Hi Jeremy,.

    It is the expected behavior. If you deploy an edge manually, you will be asked for a 'IP management', and then an IP address for the use of the uplink. It is the second IP source address. If you were to use a NAT, you get an additional IP address for each VM on the NAT's segment.

  • Configuration 'use the next available filename' in function 'write file measure. "

    My signal to record project and recording by using the function "write into a file position. I want to make the recording of signals multiple segments must have configured option «use the next available filename» For example, if the original file is data.tdms, then it saves the file in: data_1.tdms, data_2.tdms, data_3.tdms,...
    Do I use a button control enable and disable the feature of writing.
    In the past, I did normally. Now, I can't do more, now, each writing new data have been add in a single file created without the next new file as you wish, it has almost become an option "add to the file".

    I use LabVIEW 2013

    Hello ducta9,

    Looks like you're currently writing custom file Express VI configured to 'save to file' - this means that all the data for a given session will be saved in the same file.  The file number will be incremented only once the application is restarted or the Boolean Reset entry has the value True.  If you want to save on a series of files, select the option "Save to a series of files" and configure the Express VI as needed to generate new files at intervals.

    If you want to write blocks of variable data to a new file size whenever the user clicks the Activate button, you may be able to get away with wiring just a real constant for the Reset.  I would recommend when to even take a look at the options available in the recording of a series of settings files.

  • Can't see the available wireless networks

    I bought a new router (netgear300) and tried to connect to it. For some reason any would connect to my computer, but it has not been through the modem, so I uninstalled the network card and reinstalled and rebooted the computer. Now, I do not see the wireless networks available and cannot connect to anything. I tried to download the readers online, connect to the network manually, but nothing seems to work. I get 3 error messages when I try. They are; 1 reset your wireless, 2 network adapter. the NIC "atheros ar5007 802. 11 b / g wifi adapter "known issues of pilot or related equipment, 3. Make sure that the internet protocol bindings are correct. I did all the and still nothing seems to work, and I still don't see the available wireless networks. Nothing has had this problem before? My laptop is a compaq presario f700 model. I am currently using windows vista Home premium and have the cd of windows 7 Professional, but I don't know if the upgrade with this question will repair or remain the same. Someone knows how to fix this?

    Hi Mattcreatr,

    1 can connect to the router with other machines?

    Step 1:

    Make sure you have the latest NETWORK adapter drivers installed.

    Also, see if there is a software that goes along with the drivers.  If so, get the latest version of this as well.

    Update drivers: recommended links

    Step 2;

    Also, see if there is a software that goes along with the drivers.  If so, download the recent plus version and that as well.

    Also, make sure that the wireless adapter is turned on.

    a. Click Start, type network and sharing in the search box Center start and press ENTER.

    b. click on change adapter settings.

    c. right click on the connection, and then select activate.

    Step 3:

    Alternatively, you can perform a restore of the system to a restore point where you do not experience the problem and check.

    Start your computer in safe mode

    Note: When you perform the system restore to restore the computer to a previous state, programs and updates that you have installed are removed.

    To run the system restore, you can consult the following link:

  • Internal network and external network.

    Hello

    I want to use hyper-V to VMware workstation. I have a problem with that. I have 2 virtual machines, a server and a workstation. The server must be a router to an external network (internet) for the workstation.

    The server will be DNS, DHCP service and transfer to the workstation.

    In Hyper-V, it is easy, the server gets two NICS, one (internet) outside another internal. The workstation only an internal NIC work stations now takes an IP address from the dhcp on the server.

    When I try this with VMware, the workstation does not take into account server and get an address IP of VMware. Is it possible to change this, can VMware act here, as does Hyper-v?

    I thank the of for aid, Pit

    For the internal network, you can use the host only on VMware Workstation's network, and for do not receive not IP address of the DHCP server on VMware Workstation, you can disable the DHCP for the host only to a network using the virtual network Editor, see: VMware KB: using the VMware Workstation virtual network editor

  • Failed to create the external network

    Hi all.

    Well, I have deployed VIO with NSX. I created 2 virtual machines (instances) with 2 internal networks. I created router, plugged on both networks. Tried to ping of vm1 (int_net1) to the virtual machine 2 (int_net2) through router - everything works fine.

  • Problem of external network (Client)

    Hi guys,.

    After the transfer of my "production" environment, I am facing a problem with the external network (not API).

    On my lab environment it works fine, but on the production environment something strange happens: the machine can be put into service, but sometimes he gets 'customization' Openstack, sometimes not.

    Also, when it "works", I can reach a floating IP to one machine, and it works for something like 5 seconds, then this IP stops responding.

    I noticed that my switch TRANSPORT DVS Checkup complains to the VLAN ID 0 (which is not effective in these physical network cards), I use the VLAN ID 102 as the Vlan of Transport VXLAN. Is there something else I'm missing?

    My setup is composed with:

    -1 bunch of Mgmt

    -1 bunch of nova

    -1 bunch of edge.

    They are all on the same Transport area of the NSX, and connectivity to the Openstack API and the Mgmt API now works well I put almost present on 'production' (in fact it is an internal test with some users), but this external network problem is a show-stopper for me

    Thanks for the advice, sorry to bother you with so many questions

    Ah, an offtopic question: when you release the 2.0 version? Is it going to be compatible with the 1.0 version, or I have to remove and reinstall my whole environment? (VMworld, probably?;) (P)

    Thanks again!

    Reading your post, I understand that you have 2 numbers:

    Problem with the metadata service (give the host name):

    Communication to the metadata service works like this:

    Can you do some tests for me.

    1 test VXLAN connectivity between the ESXi-Compute (hosting your VM of Instance OpenStack) and the edge of ESXi (hosting your logical shared edge router)

    Ping ++ netstack = vxlan x.x.x.x (to test the connectivity of your IP)

    Ping ++ netstack = vxlan d s 1570 x.x.x.x (to test the MTU on the physical fabric is 1600 or greater)

    Note: x.x.x.x is the remote IP of VXLAN ESXi @.

    If this test does not work, then your VM can speak to its default gateway correctly.

    If this test does NOT work, then it is probably a problem with the physical fabric (VLAN misconfigured or MTU misconfigured).

    2 validate connectivity VLAN between the edge of ESXi (hosting your edge of metadata) and ESXi-Mgt (hosting your LoadBalancer VIO)

    . SSH to the VIO - WHO

    . then make a SSH for balancing load-VIO ssh loadbalancer01

    . can do a ping to Metadata Edge1 ping x.x.x.x (ping should fail, BUT you should see an ARP entry for that IP @: arp - na)

    Note: You can find the Edge Mgt IP metadata @ under edition of the edge metadata_proxy_router_xxx NSX and its uplink interface checking.

    If this test does not work, your edge of metadata can talk to VIO load balancing.

    If this test does NOT work, then it's probably a problem with the Mgt ESXi and ESXi points not to the same port of Mgt group.

    Problem with the external network:

    You validate people can talk to the VM floating IP @?

    If this isn't the case, it is probably because the edge of ESXi (hosting your logical shared edge router) is not on the right VLAN.

  • Not enough external IP for external network access

    Hello

    I am a newcomer to Lab Manager and my Department has not enough IPs to work until several virtual machines on LabManager. If we think about the use of private network as 192.168.x.x address to create a configuration and we checked which is supported using the virtual network model. But the question is whether I would like that all the virtual machines in this network is able to access the external network vLabManager will try once again each of the virtual machines assign an external IP address that we are lack of.

    So my question is the gateway for network in a configuration can be used as a router a provide NAT to allow virtual machines in a network deprived of access to external sites? Or other solutions better to solve our problem of IP all allow the virtual machines to access the external network?

    Thank you.

    The previous reviewer mentioned that NATing is supported (VMware calls this "fence"). If you are exposing ALL the machines in your configuration on their own fenced address, you will not get IP address consumption savings you want. To reduce the number of IP addresses externally exposed in a NAT configuration, you should design your configuration so that only a single IP address is exposed through the fence. A similar debate along these lines took place here: http://communities.vmware.com/message/1245907#1245907

    In a configuration of 4 machine you can put 4 machines on a network "dark." One of these devices will have to be multihomed on two networks. The hosted machine multi risk exposing his unique IP address either on the network or through a closed network directly. In both cases, only a single address would be exposed on your external network and you can use it as a gateway into the 3 other machines.

    Would be nice if the router fence could be directly configured to support some simple flavor of tunneling. Currently this capability is not there.
