How might one filter out Cisco 4510 "controlled" and "uncontrolled" ports from monitored NPM interfaces?

NPM discovers Cisco 4510 three interfaces for every physical switchport. One "normal" one that we'd always monitor, plus two virtual ports ("controlled" and "uncontrolled") that use the same physical interface name. These virtual interfaces have to do with Cisco's implementation of security practices (see my discover of this here: Re: Unknown Additional Interfaces as Uncontrolled/Controlled on SUP8 )

NPM's pretty powerful. Is there a way to use its power and flexibility to List Resources on a 4510 and automatically check or uncheck interfaces whose name or description includes "controlled" and / or "uncontrolled"?

As it works today, if I click "All", then I get three times as many elements added as I need. If I select "Active Only" ports, then I still get three times as many is required, plus I lose the ability to monitor ports currently inactive. But they may be active in an hour or a week, and I'd like an option to select "All ports EXCEPT controlled and uncontrolled".

How would you try to do this?

I have done this with Network Discovery by using the Advanced filtering options in the import phase, but I have not found an easy way to do this with the List Resources function. It would be useful to have some kind of easy filtering there as well.

rschroeder

Agreed. Are you running NPM 12.1?

jhandberg

Yes we are.

As an indirect kind of work-around I run a powershell script to delete interfaces though the API, that way I can filter on any kind of criteria I can dream up using a swql query, just tweak the $query bit to be something along the lines of where i.caption like '%controlled%'

If you need more examples to help you work with the api you can check them out here

OrionSDK/Samples/PowerShell at master · solarwinds/OrionSDK · GitHub

$ErrorActionPreference = 'Stop'

# load the module

if (-not (Get-PSSnapin | ?{ $_.Name -ceq 'SwisSnapin' })) {

Add-PSSnapin 'SwisSnapin'

}

# define the hostname of the SolarWinds server

$hostname = 'x.x.x.x'

# create a connection to the SolarWinds API

$swis = Connect-Swis -Hostname $hostname -Trusted

# build the query in SWQL

$query = @"

SELECT

i.Caption

,i.Uri

FROM Orion.NPM.Interfaces i

WHERE i.Caption LIKE '%0000%'

# run the query and assign the results to the $interfaces array

$Interfaces = Get-SwisData $swis $query

# iterate over the array

foreach ($int in $Interfaces) {

# write out which interface we're working with

"Working with interface: $($int.Caption)..."

# delete the interface

Remove-SwisObject $swis -Uri $int.Uri | Out-Null

}
