Vlan 1 Hight transmit

soheilamiri

hello 

recently solarwinds show me and alarm that my Vlan 1 utilization is above 85%. we had no change. the device is cisco nexus 3064

the traffic is only on one switch and only on VLAN 1. no traffic is on port and also the vlan 1 is shutdown. 

what the matter ?

VLAN 1 appears to be shutdown, so that's odd that you would be seeing traffic on that VLAN. Regardless, it's rare but not completely unusual that the interface bandwidth speed returned from the device is incorrect. This happens more often with virtual interfaces, such as VLANs. 

You can override what the device is reporting by editing the interface in Orion and adjusting the in and out bandwidth limits for this interface. Given this is a VLAN, I would recommend 10GB. Right now it looks like it's set for 1GB.
