Extreme Management NBI Query Stacking

[CSchneider-Weic]

Hello,

I am trying to automat some processes for documentation with scripts. I am looking for a NBI query which gives back the model and Serial numbers of a Summit Stack. Can someone help me?

Kind regards

Hey everyone,

To add to this: The information “serials in a Summit Stack” actually is available via NBI on a per-device query basis.

{
    network {
        device(ip:"1.2.3.4") {
        id
        deviceName
        deviceData {
            macAddress
            ipAddress
            vendor
            family
            subFamily
            deviceDisplayType
            nosId
            firmware
        }
        entityData {
            deviceTopology {
                entPhysicalDesc
                entPhysicalModelName
                entPhysicalName
                entPhysicalSerialNum
            }
        }
    }
}

The serials for each slot will be included as entPhysicalSerialNum.

Please note that this works for exactly the use case stated. Do not rely on correct information for other use cases, there is a long list of caveats with that API call (sorry, cannot disclose, customer-paid work)… And, as usual with the NBI, doing a refresh before firing the query is a good idea.

Hello Stephan,

yes that helps. Next time I will check on GitHub first.

Thank you.

Kind regards

Hello Christoph,

unfortunately there is no official guide for Python Scripting with XMC. But you can find many official examples under Task -> Scripts and Workflows not only the VLAN scripts.

More examples can also be found here: https://github.com/extremenetworks

For your concrete problem here a small example (quick and dirty) how to query a switch  (XOS only!) and then output the serial numbers.

import re


#Send CLI commands
def sendConfigCmds(cmds): 
    for cmd in cmds: 
        cli_results = emc_cli.send( cmd )
        if cli_results.isSuccess() is False:
            print 'CLI-ERROR: ' + cli_results.getError()
            return False

    return cli_results.getOutput()

#Use allways a main function in XMC
def main():
    commands = []
    commands.append("show version") 


    result = sendConfigCmds( commands )

    if result:
        result_lines = result.splitlines()


        for line in result_lines:
            match = re.search("Slot.*?:",line)
            if match:
                line_parts = line.split()
                if len(line_parts) > 2:
                    print("Serial: " + line_parts[3])
#Start program
main()

Here is what you will see with “show version”:

Slot-1 sw001 # show version
Slot-1 : 800601-00-18 8914N-46722 Rev 18 BootROM: 1.0.2.1 IMG: 22.7.1.2
Slot-2 : 800601-00-18 8912N-46755 Rev 18 BootROM: 1.0.2.1 IMG: 22.7.1.2

Here is the output:

Serial: 8914N-46722

Serial: 8912N-46755

Hope that helps.

Hi Stephan,

can you may help me out? I see an example Python script for executing CLI Commands in the XMC but it seems to be for VLAN configuration. Is there a documentation for how to execute CLI commands via python this? Do you may know how to do it and tell me?

Kind regards
