                  Check CPU load.<br>
                  If you have high bcm_RX or something, than you have a
                  lot of traffic towards CPU that may cause this
                  behaviour.<br>
                  <br>
                  We had this problem because on one VLAN we have around
                  800Mbit/s of ethernet broadcasts (specyfic traffic -
                  mirror from router forwarded towards vlan).<br>
                  <br>
                  This (broadcast to CPU even if VLAN is L2 only) is a
                  bug admitted by extreme, will be corrected one day ;)<br>
                  In meantime we have a filter that blocks broadcasts to
                  go to CPU on that vlan.<br>
                  <br>

              Hi, tnx for your answer, but I have non traffic on on
              these devices. I have only switch they on.<br>
