If you do not wish to un-install these applications and plan to use them in
the future, you can Start and Stop VLAN Manager and Address Tracker
specific daemons by doing the following:
1 Proceed to /usr/3Com/diagnostics directory and run:
./tncs_diagnostics.sh
This requires that you have root access to the workstation. Stopping
these daemons prevents any background SNMP polling on the
network.
2 Verify the daemons have shutdown by using the ps command as follows:
a For Enterprise VLAN Manager:
ps –ef |grep NCD
should not list any
Enterprise VLAN Manager daemons.
b For Address Tracker:
ps –ef |grep atservice
should not list
atservice daemon.
Enterprise VLAN Manager background daemons are invoked
automatically. Please use the
tncs_diagnostics.sh
script after you
restart NNM so that you can stop the VLAN Manager daemons once
they are started.
Another way to prevent VLAN Manager from polling: The
/usr/3Com/ncd/runtime/sav directory contains all files comprising the
Enterprise VLAN Manager database. These files are
127.0.0.1.ppp
,
{NMS
IP}.6790.PDP
, and
{NMS IP}.ppp
and should be moved somewhere else
or renamed with a
*.old
extension. Without a network database no
SNMP polling is executed even if the background daemons restart.
Clearing the Address Tracker database: Address Tracker polling is
independent of the database (
atdatastore.dat
). If it does not find this
file at application startup, it is created automatically. Therefore, clearing
the
atdatastore.dat
file does not stop Address Tracker from polling.
