VLAN Change through UDT & NCM using Orion SDK

Hi,

We have installed the UDT and NCM modules, we have a requirement like,

1. User will given an input as IP Address.

2. Through UDT with this IP Adrress, we need to identify the Port and VLAN.

3. We need to pass the identifed port, VLAN from UDT, along with new VLAN to NCM module for changing the VLAN.

We are using .net for this requirement, while going through the SDK, its clearly mentioning about the Invoke mentod for acknowledgeing an Alert.

So can we achive our requirement of changing a VLAN with this Invoke method ?

While going through the discussion fourm, http://thwack.solarwinds.com/message/178759#178759

we found the PowerShell script, it attached herewith.

In this script we identified below line,

Invoke-SwisVerb $swis Cirrus.ConfigArchive Execute @($nodeIdList, $script, $username) | Out-Null

Is there any similar code available in .net, like

swis.Invoke("Cirrus.ConfigArchive", "Execute", System.Xml.XmlElement[] parameters), we don't know what is the format of this XmlElement[] parameters.

Please provide the sample XmlElement[] for this. It will be very helpful.

Also with this Invoke method, our requirement of changing a VLAN will work?

Please help us to find out the solution for this requirement.

Thanks,

Arun

For getting the arguments into the "XmlElement[]" format in C#, try something like this:

private static XmlElement[] PrepareInvokeArguments(params object[] args)

{

var elements = new List<XmlElement>(args.Length);

foreach (var arg in args)

{

var dcs = new DataContractSerializer(arg.GetType());

var doc = new XmlDocument();

using (var writer = doc.CreateNavigator().AppendChild())

{

dcs.WriteObject(writer, arg);

}

elements.Add(doc.DocumentElement);

}

return elements.ToArray();

}

Yes, you should be able to change a VLAN using Cirrus.ConfigArchive.Execute, but your code will need to prepare the appropriate command line script for the switch in question. If you use switches from different vendors, this will mean generating a different script using different syntax according to which switch you are updating.

Thanks for the support...

In the specified method, PrepareInvokeArgument(param object[] args) what values we need to pass as args?

Whether the parameter "args" will contain the values of port, vlanid and new vlanid for changing the vlan? or any specific format for args?

Also how do identify the switch to run the script? It will be very helpful for us if you are providing the vendor specific command line script.

Thanks,

Arun

Here is a Pearl script to do the same ...Cisco and Juniper..., You need to pass few inputs-- Vendor, Interface Name, Cisco VLAN ID (if vendor is Cisco), Juniper VLAN member (if vendor is Juniper) and existing VLAN . And yes another input is "Switch IP" to which script will do ssh/telnet with credentials.Now not sure whether similar script can run through this SDK or not.

Please help us to find out the solution for VLAN change,

Through SDK, we found out for Cirrus.ConfigArchive.Execute, expects 3 parameters,

1. NodeID

2. Script

3. User

Node Id and User parameter we will get, but

We have the doubt like what value need to pass as Script, in the above post in Perl, handled two vendors Cisco and Juniper.

If so then we need to have separate scripts for these two.

It will be very helpful, if you provide the scripts that need to pass through .net framework.

Thanks

Arun
