I’ve been asked for a report on how many ports we have on our network and how many are used. Without going to each device and running a sh int status command I’m wondering if there are any forms anyone might have for NPM
Do you have NCM? I can see that if you do an SWQL query using NCM.Nodes and NCM.Interfaces you could pull a report by device name with a count on admin status Up/down/total per device.
This is something I pulled together real quick using SWQL to display "Device Name, Device IP, then "interface" by Admin Up/Down and Oper Status Up/Down along with Total available. I added a where statement to only return "physical interfaces" because I believe that's what the original intent was of the question on this string. So a device like a Cisco Catalyst 3560 w/ 48 ports would show as 52 interfaces (48 ports + 4 SFP). For scaling the way it's written right now it will return every device in NCM.Nodes. In some enviornments that could mean more than network devices.
rschroeder this returned 1523 rows for me so scale wise it shouldn't be an issue. As long as all the devices you're looking for information on are managed/in NCM. To clarify this is NCM not NPM and it will return all ports/interfaces on the device even those not discovered by NPM/NCM. In my environment we only discover trunk ports and/or "important" ports so using NPM wouldn't return the same results as it would only be able to return discovered ports/interfaces.
NodeCaption AS [Device Name],
AgentIP AS [Device IP],
CASE WHEN n.Interfaces.AdminStatus = 'Up'
THEN 1 ELSE NULL END
AS [Admin Up],
CASE WHEN n.Interfaces.OperStatus = 'UP'
THEN 1 ELSE NULL END
AS [Oper Up],
CASE WHEN n.Interfaces.AdminStatus = 'Down'
THEN 1 ELSE NULL END
AS [Admin Down],
CASE WHEN n.Interfaces.OperStatus = 'Down'
THEN 1 ELSE NULL END
AS [Oper Down],
n.Interfaces.PhysicalInterface = 'Y'
pparsaie Is there line I can add, or an option I can enable, in your report that will display the sum of all ports, for a "Total Ports Across All Nodes" entry?
Obviously I can export it to Excel and run the Summary function on a one-time or as-needed basis, but it would be an attractive feature to show Total Ports on ALL nodes instead of only one EACH node.
This helps greatly as has got me pointed in the right direction. Although I am horrible with SWQL, was wondering if there is a way to get the total ports like above but base it on a custom property of the nodes, So lets say all my network nodes have a custom property call Allocation ID, is there way to pull total port counts of the sum of all the nodes based on the Custom Property (Allocation ID) that is assigned to them?
An example would be something like:
AllocationID Name Admin Up Oper Up Admin Down Oper Down Total
Boston 52 18 0 34 52
New York 23 11 5 17 28
usmanshaikh - try changing the 'Up' and 'Down' to 1 and 2 (WHEN ncmi.OperStatus = '1')
(*) AS "Total Ports", SUM (IsUp) AS "Used Ports", SUM (IsDown) AS "Oper Down Ports", SUM (IsAdminUp) AS "Admin Up Ports", SUM (IsAdminDown) AS "Admin Down Ports"
WHEN ncmi.OperStatus = '1' THEN 1 ELSE 0 END AS IsUp,
WHEN ncmi.OperStatus = '2' THEN 1 ELSE 0 END AS IsDown,
WHEN ncmi.AdminStatus = '1' THEN 1 ELSE 0 END AS IsAdminUp,
WHEN ncmi.AdminStatus = '2' THEN 1 ELSE 0 END AS IsAdminDown
NCM_Interfaces NCMI INNER JOIN NCM_NodeProperties NCMNP ON (NCMI.NodeID = NCMNP.NodeID)
JOIN NodesData ND ON (NCMNP.CoreNodeID = ND.NodeID)
BY NodeID, Caption
BY Caption ASC
I gave your process a shot in SDK, but it came back with this error:
Is that a SWQL query, and if so, I'm not certain how to correct the error based on the screen shot above. What are your recommendations?
User Device Tracker also contains port count information and port-up and port-down information. It's not as useful to me for repurposing ports on an individual switch basis as my custom report is, but it does serve a purpose for higher-up planning.
You may be able to copy & edit either of these two reports to get the information you desire.
You can create a custom report that uses SQL or SWQL input in its advanced Database Query area by going to
you can create the report that I use by following the instructions here:
If you have the SDK, you may be able to find a pre-created query that accomplishes what you need; I haven't found one there yet. sqlrockstar might be a great resource for discovering what SWQL query would provide the desired information.
As I understand this thread, the original request is to find a way to:
I think it would be useful to include how long any port without link has been down.
I like the concise output of your report, but it doesn't provide the information I needed. I was searching for a method of discovering how long inactive ports have been inactive. The sole focus is discovering the length of time that inactive ports have stayed inactive, and sorting them by duration of inactivity.
The goal is to discover ports which have been inactive for a very long time, and then make them available for new devices by unpatching them.
The method I created here, How to create a report displaying the Last Time Data was Transmitted or Received on a Switch Port , does exactly what I need on a per-switch basis.
It would be interesting to see a report that provides the same inactive port duration for all switches in an enterprise . . . It would have to separate out nodes by some criteria (node name, preferably), and scale to hundreds or thousands of switches, each of which could have several hundred ports. But for now, I'm satisfied with the method I built that collects the duration of port inactivity on a single switch.
Not for NPM. Within NPM you specify which ports are monitored. For example, on a 24 port access switch, we typically monitor the trunk ports. That's just 2 ports on the switch. By the way, you can designate the other ports as plugged/unplugged and get a capacity report that way, but this is not typically done.
For knowing how many ports in the network are active, the User Device Tracker (UDT) module would be a better fit. The UDT module will monitor all ports on switch and keep track of MAC level information and will provide a port capacity report.
I would recommend you install the evaluation version of UDT to see if it gets you the functionality you need.
