## Symptoms

- * High CPU utilization on the Virtual Switch.
* Virtual Switch interfaces named **wrp\<Number\>** and **wrpj\<Number\>** have the same MAC address.

  <br />

## Cause

When you create a Virtual Switch in an R80.30SP environment with Jumbo Hotfix Take 49 / Jumbo Hotfix Take 56, virtual interfaces with names that start with **wrp\<Number\>** and **wrpj\<Number\>** have the same MAC address.  

This causes traffic from the External Switch to the Virtual System (through the Virtual Switch) to be handled by the Virtual Switch.  

This may cause high CPU utilization on the Virtual Switch.
