Network Switch/Router Wizard Port Speeds

[CarlWedu]

Seem to be unable to get the port speeds be recognized at potential for 10gb ports universally and 1gb ports are being set based upon current auto-negotiation settings rather than the capabilities of the port, which I think means that anytime a port is changed the service related to that port would have to be removed and updated.

2nd point there is not ideal, but can work around it. Would very much like to have 10gb ports displayed correctly though. I saw a previous forum topic discussing some development around the wizard (our version is 2.3.1;) have the necessary enhancements been included in our version, and if not, are they to be released soon? Any other workarounds?

Thank you!

2.3.1 is the latest.

I don't have any high speed port devices to test with, please PM me a copy of your /etc/mrtg/conf.d/DEVICENAME.cfg for one that has those high speed ports so that I can review it.

Thank you

On your first point, what switch or router make/model are you using? There were some hang-ups with Cisco MDS in past, as seen in this thread:
https://support.nagios.com/forum/viewto ... 16&t=32979

On your second point, are you talking about graphing and could provide a link to the forum post you mentioned?
Could you post a screenshot of the incorrect display you presently see?

These are fresh adds, so no .cfg files as yet.

That is the thread I referenced in my opening post on this topic. I tried the bandwidth setting on the int as directed in the following post, but it had no effect. The int still gets set at 4.29 gb rather than 10.

Our wizard prioritizes different detected speed values (acquired through snmp) in the following order:
1. Bandwidth Setting (device specific setting)
2. Reported ifSpeed
3. Finally, Link Speed if all else fails.


Thinking it may be a model issue, I tried both Cisco 2960X and 3750E switches--same results. I have attached a screenshot of the issue from the 2960X.

Hi folks,

That past thread was mine regarding the MDS and interface speed.

I believe the cfgmaker code may to change to support higher interface speeds. The ifSpeed OID is 32-bit object, which means it can't support interface speeds greater than 4.2 GB. These MDS devices have another OID called ifHighSpeed for each interface, which will show the correct speed of interface.

Example: Here is an 8GB interface on 1 of our MDS switches
IF-MIB::ifSpeed.18440192 = Gauge32: 3705032704
IF-MIB::ifHighSpeed.18440192 = Gauge32: 8000

Nagios will show the speed as 3.71 GB via the wizard. For the workaround I have to change the WARN and CRIT for in/out speeds in the wizard to indicate it is in fact at 8GB speeds.

I'm happy to provide more info, or to test things out.

Thanks brdr, that would help, so does your MRTG cfg files in /etc/mrtg/conf.d show anything that we can use to get that information or will we have to reach out with SNMP first?

Here is the snippet from mrtg for the interface in my post above. Not much ;-(

CarlWedu and brdr, please edit this file:

Code: Select all

/usr/bin/cfgmaker

And tell me the version that is at the top, it looks like MRTG should support ifHighSpeed from looking at mine (2.17.4) but I want to verify.


Thank you
