Traffic alert > 100%
« on: August 05, 2015, 09:41:39 AM »
Gruezi!

Today NeDi brought me a few events from an HP Switch (HP2810-24G), some interfaces had a very weird traffic counter.
Here are the events:

Quote
[Alert]    5.Aug 15 8:00    DeviceName    [Port Outbound Traffic (ifto), Device Status]    9 (Alias) (1G) has had 176% outbound traffic in the last 3600s, exceeds alert threshold of 75%!

[Alert]    5.Aug 15 8:00    DeviceName    [Port Outbound Traffic (ifto), Device Status]    8 (Alias) (1G) has had 2009% outbound traffic in the last 3600s, exceeds alert threshold of 75%!

[Alert]    5.Aug 15 8:00    DeviceName    [Port Outbound Traffic (ifto), Device Status]    4 (Alias) (1G) has had 146% outbound traffic in the last 3600s, exceeds alert threshold of 75%!

[Alert]    5.Aug 15 8:00    DeviceName    [Connection Outbound Traffic (lnto), Device Status]    2 (Alias) LLDP:OtherDevice,11 (1G) has had 3153% outbound traffic in the last 3600s, exceeds alert threshold of 75%!

[Alert]    5.Aug 15 8:00    DeviceName    [Port Outbound Traffic (ifto), Device Status]    18 (Alias) (1G) has had 245% outbound traffic in the last 3600s, exceeds alert threshold of 75%!

This device is not really the perfect example of this issue because it has a very high uptime but I have already seen this problem with events on two different Cisco devices (N5K-C5596UP and WS-C6509IOS) that showed an inbound and outbound traffic of 101%.

I have no errors in verbose mode about these devices/interfaces. I wanted to understand how it was possible and to know if it was a bug.

I have already seen a topic about this issue but it was on an old version of NeDi.
I use NeDi 1.4.

Thanks

It's usually related to wrong interface speed reported by the device. This can also happen if a port changed speed (e.g. something was plugged in) within a discovery cycle...

I have same problem with our Cisco Switches, but the alert is regarding VLANs.
So it is sensless to place a bandwidth parameter on vlan interfaces and on non routed
vlans it is not possible to configure a bandwith.

How can I get rid of these alarms?

Thank you very much for your work!

With 1.4 you can set a traffic alert threshold of 100% in Devices-Interfaces to ignore such interfaces. Set a filter to match the interfaces in question, enter 100 next to the binoculars and click Update
