If applications involving address table polling are run on an active
production network, the SNMP polling can contribute to unexpected
events in the high-availability configuration, such as MPLA links down
and STP topology changes. It is recommended these applications that
involve address table polling be used during initial configuration or during
problem isolation instead of during active, busy network periods. For
more information about this issue, please visit the 3Com Knowledgebase
on the 3Com Web site.
Applications such as Enterprise VLAN Manager and Address Tracker have
background daemons that continue to poll the network even when the
GUI (or front-end) applications are not running. The devices that may be
affected are the Switch 4007, CoreBuilder 9000, CoreBuilder 9400,
CoreBuilder 3500, SuperStack II Switch 9300, and SuperStack II Switch
3900 (all running 3.0.0 software).
If you are not using the Enterprise VLAN Manager and Address Tracker
applications you should un-install these applications with the Transcend
un-install utility. When applying the Transcend patch, the patch
installation utility looks to see which applications are installed and
patches those applications only.
1 Proceed to the /usr/3Com/install/bin directory
2 Run the
./deinst.scr
Tracker applications for de-installation.
Be aware that even though the application GUI is not running, there are
several background daemons that are running. These daemons handle
SNMP polling to the devices. Network problems (as described above) may
occur if these daemons continue to poll the device address tables.
Stopping VLAN Manager and Address Tracker specific daemons prevents
SNMP polling. To stop these daemons from running, you need root access
to the workstation.
