I have a computer1 connected to ip phone which is connected to an HP J9625A switch like this:
switch <-> ip_phone <-> computer1
l have been continuously receiving snmp traps close to 10000 traps with the following traps on computer2:
port 4 is now off-line port 4 is Blocked By STP
I noticed in the snmp trap event screen that there were no "port 4 is now on-line" entry. Testing the connection from the switch port 4 to the ip phone with a cable tester indicates that a problem exists with the connection. Yet I do not understand why STP would block this port.
