Ordering Softlayer Vlan pairs

问题:

I've done some searching on stackoverflow and looked through the API but can't seem to find an answer specifically. I'm creating some automation scripts in python and wondering if there's a way to grab the primaryNetworkComponent and the primaryBackendNetworkComponent pairs and based on location? There's the getVlans() method but not sure which vlans go together unless i go to the gui. Is there no limit to the number of machines that can be on a vlan pair? if there isn't would it just be acceptable to grab the router and just take the first 2 vlans?

The below script can help to retrieve vlans from specific location:

    # Getting the VLANs
    vlans = client['SoftLayer_Account'].getNetworkVlans(mask=objectMask, filter=objectFilter)
    # Print vlans
    print("PRIMARY NETWORK COMPONENT")
    for vlan in vlans:
        if vlan['networkSpace'] == 'PUBLIC':
            print("Id: %s     Vlan Number: %s      Primary Router: %s" % (vlan['id'], vlan['vlanNumber'], vlan['primaryRouter']['hostname']))
    print("\nPRIMARY BACKEND NETWORK COMPONENT")
    for vlan in vlans:
        if vlan['networkSpace'] == 'PRIVATE':
            print("Id: %s     Vlan Number: %s      Primary Router: %s" % (vlan['id'], vlan['vlanNumber'], vlan['primaryRouter']['hostname']))
except SoftLayer.SoftLayerAPIError as e:
    print("Unable to get Vlans. faultCode=%s, faultString=%s"
          % (e.faultCode, e.faultString))

There is no limit for number of servers in a public vlan, but it depends from the available ip addresses , the same situation for private vlan. In case of private vlan has a limit of 256 ip addresses.

If the vlan has a hardware firewall, it has a limitation of 30 servers (VSIs or BMSs).

It's not possible to retrieve the first vlans from router, because this is something restricted, you only will be able to retrieve the vlans that you purchased.

i have this code

mask = 'id, hostname, domain, hardwareStatus, globalIdentifier, remoteManagementAccounts, primaryBackendIpAddress, primaryIpAddress'
    hardware_list = mgr.list_hardware(mask=mask)
    for hardware in hardware_list:
        if "someGLobalID" == hardware['globalIdentifier']:

in which i'm trying to get the global identifier but i keep getting a key error

Do global identifiers get generated after an order is completed and in the deploy status?

I tried searching a different key like domain and it works

I have success with the following script:

You are right, the global identifiers are generated in the order receipt, but they are attached to the servers until the provision proccess finish. So, it's necessary to wait until the provision process from a server finishes, to search by this.
