EPICenter Software Installation and User Guide 25
Topology Views
The EPICenter software’s Topology applet allows you to view your network (EPICenter-managed
devices and the links between Extreme Networks devices) as a set of maps. These maps can be
organized as a tree of submaps that allow you to represent your network as a hierarchical system of
campuses, buildings, floors, closets, or whatever logical groupings you want.
The Topology applet can automatically add device nodes to your map as devices are added to
EPICenter software’s device inventory. The EPICenter software automatically detects and adds links
that exist between Extreme Networks devices, and organizes the device nodes into submaps as
appropriate. The links between devices provide information about the configuration and status of the
links.
You can customize the resulting maps by creating submaps, moving map elements within or between
submaps, adding new elements, such as links, “decorative” (non-managed) nodes, and text, and
customizing the look and labeling of the discovered nodes themselves. In addition, options are available
to organize and optimize the map layout to display very large numbers of devices with the minimum of
device and link overlap.
The Topology applet also provides information about the VLANs configured on devices in a topology
view. Using the Display VLANs feature, you can visually see which links and devices are configured for
a selected VLAN, or select a specific device or link to see what VLANs are configured on that device.
You can also configure a VLAN in a topology by adding ports or trunk links.
Finally, from a managed device node on the map, you can invoke other EPICenter functions such as the
alarm browser, telnet, real-time statistics, a front panel view, the VLAN Manager, or ExtremeWare Vista
for the selected device.
Enterprise-wide VLAN Management
A virtual LAN (VLAN) is a group of location- and topology-independent devices that communicate as
if they were on the same physical local area network (LAN).
The EPICenter VLAN Manager is an enterprise-wide application that manages many aspects of VLANs
on Extreme Network’s Summit, BlackDiamond, and Alpine switches. Any EPICenter user can view
status information about the VLANs known to EPICenter across the network. Users with the
appropriate access can create and delete VLANs, add and remove ports from existing VLANs, and
create and modify the protocol filters used to filter VLAN traffic. When creating or modifying a VLAN,
you can get EPICenter to determine whether there is connectivity between the devices you have
included in the VLAN, and if not, it can recommend what ports and devices you should add to achieve
connectivity.
The ESRP Manager
The Extreme Standby Router Protocol (ESRP) is a feature of ExtremeWare that allows multiple switches
to provide redundant layer 3 routing services, as well as layer 2 redundancy, to users. The ESRP
Manager displays the status of ESRP-enabled VLANs and the ESRP-enabled switches in those VLANs.
You can view a summary status for all the ESRP-enabled VLANs being monitored by the EPICenter
software. You can also view detailed information for an individual ESRP-enabled VLAN and the
switches in those VLANs.
