Any idea why ports go off with STP?
So, just on one IDF where i work at is having a problem where users loose connection for a brief second and then it comes back again.
TRAPMGR[trapTask]: traputil.c(721) 4767001 %% NOTE Link Up: Gi1/0/35
TRAPMGR[trapTask]: traputil.c(721) 4766998 %% NOTE Gi1/0/35 is transitioned from the Forwarding state to the Blocking state in instance 0
TRAPMGR[trapTask]: traputil.c(721) 4766997 %% NOTE Link on Gi1/0/35 is failed
TRAPMGR[trapTask]: traputil.c(721) 4766996 %% NOTE Link Down: Gi1/0/35
TRAPMGR[trapTask]: traputil.c(721) 4766993 %% NOTE Gi1/0/35 is transitioned from the Learning state to the Forwarding state in instance 0
TRAPMGR[trapTask]: traputil.c(721) 4766992 %% NOTE Gi1/0/35 is transitioned from the Forwarding state to the Blocking state in instance 0
TRAPMGR[trapTask]: traputil.c(721) 4766991 %% NOTE Link Up: Gi1/0/35
TRAPMGR[trapTask]: traputil.c(721) 4766988 %% NOTE Gi1/0/35 is transitioned from the Forwarding state to the Blocking state in instance 0
TRAPMGR[trapTask]: traputil.c(721) 4766987 %% NOTE Link on Gi1/0/35 is failed
all ports are configured with port-fast STP, and have access to the data and voice vlan, any idea why it's doing this and how to fix it?

Hi,
Which model switch is it? I would check the cable. You may also want to make sure the firmware is up to date.

It's a N3048P, the cables are properly installed, and certified. how could i check the firmware? I have no experience when it comes to Dell switches.
