High output utilization on interface Vlanxxx

Hello everyone, thanks for the support, I present the following problem with a Nexus 7 K that in the monitoring tool provides me with the following message

Hola buenas tardes, mucas gracias por responder la imagen de la falla no la puedo cargar  pero indicio  la falla presentada en la herramienta de monitoreo es la siguiente:

High output utilization on interface Vlan7xx

Oh ok, perdona por no haberlo entendido antes,

En ese caso te voy a recomendar leer la respuesta de Richard Burts en este post: https://community.cisco.com/t5/switching/what-is-the-max-bandwidth-of-a-l3-vlan-interface/td-p/2856178 te la copio igual acá:

 The Solarwinds report was written for monitoring physical interfaces and it works well for physical interfaces. If the report says that the interface transmitted 32% or 64% or some other % then you knew with some accuracy how close you were to maximum utilization of the interface. But when it is monitoring a virtual interface like vlan 8 it does not really mean the same thing.

Let me try to explain it in this way - if Solarwinds says that vlan 8 is using 64% of 1 Gig, then it is saying that 64% of 1 Gig was the aggregate utilization going out all of the physical interfaces in vlan 8. If there are, perhaps, 8 physical interfaces in vlan 8 then realistically each physical interface is at about 8% utilization and the 64% reported on the virtual interface is really not alarming. You might try using the bandwidth command in interface config mode for vlan 8 and set some value higher than 1 Gig and see if that helps with the reporting.

Creo que esto explica exactamente el comportamiento que estas teniendo, quizá si cambias manualmente el BW en la interfaz vlan (aumentándolo) tu herramienta podría calcular basado en un valor mas real.
