Your program with the logging capability should look like this:
from exos import api
import exos.api.throwapi as throwapi
import logging
logger = logging.getLogger('test')
logger.setLevel(logging.DEBUG)
logHandler = api.TraceBufferHandler("testbuf", 20480)
logHandler.setLevel(logging.DEBUG)
logHandler.setFormatter(logging.Formatter("%(levelname)s:%(name)s:%(funcName)s.%(
lineno)s:: %(message)s"))
logger.addHandler(logHandler)
def event_cb(event, subs):
logger.info(event)
ev = throwapi.Subscription("vlan")
ev.sub(event_cb)
You now can access the information when reading the trace buffer of your application:
sw1.50 # create process test python-module test start auto
creating test...
sw1.51 #
sw1.51 # create vlan 10-12
sw1.52 #
sw1.52 # debug ems show trace test testbuf

Move a port from one VLAN to another to trigger additional information.
sw1.53 # config vlan 12 add port 1
VLAN 12 VLAN_0012: Port 1 untagged has been auto-moved from VLAN "VLAN_0042"
to "VLAN_0012".
