It is possible to disable RMON statistics for the Topology applet as a whole, so that the Rmon
Statistics checkbox will not have any effect. This is done setting RMON properties on the Server
Properties page of the Administration applet.
Adding Map Background Images
You can add images of your own to use as background images for topology maps by placing them in
the
BackgroundImages
directory in the EPICenter server installation.
Both
.gif
and
.jpg
image types are supported.
Background images are kept in the directory
< epicenter_install_dir >\extreme\gifs\topology.BackgroundImages
where
< epicenter_install_dir >
is the root directory of your EPICenter server installation (by default
epc4_1
in the Windows operating environment, or
/opt/extreme/epc4_1
on a Solaris system
)
.
Displaying VLAN Information
The Topology applet can provide information on the VLANs configured on the switches in a map.
VLAN information is not displayed by default.
You can view VLAN information in several ways within the Topology View applet:
• By VLAN , which highlights all devices and links on the current map with ports in a selected VLAN.
• By device , which displays a list of VLANs configured on the selected device node.
VLAN information for links is always displayed in the Map Element Description Panel whenever a link
is selected, regardless of the VLAN Display mode.
To enable the VLAN information display for devices on a map, do one of the following:
• Click the VLANs icon in the Topology applet Toolbar.
