Eaps Domain And Device Status - Extreme Networks EPICenter Guide Manual

EAPS Protocol Monitoring and Verification
The EAPS map shows all the devices managed by EPICenter with respect to their EAPS implementation,
including the EAPS-related links between devices and a summary status for each device and for each
EAPS domain.
NOTE
If some of the devices in an EAPS domain are missing from EPICenter's inventory database, those devices will not
appear on the EAPS map. The EAPS domain status will correctly reflect the status of the entire domain, but it may
be difficult to troubleshoot domain operational problems that occur within nodes or links that are not shown on the
map.
It is strongly recommended that you add all the nodes in your EAPS configuration to your EPICenter inventory
database.
The Viewport is the visible area of the map: if a map is larger than can be displayed within the
Viewport, the Map Overview feature lets you view a thumbnail view of the entire map, and lets you
position the Viewport within it. Clicking the small boxed arrow in the lower right corner of the
Viewport activates the Map Overview.
Clicking the button displays the Map Legend, which defines the icons and colors that
? Legend
represent domain, device and link status as shown on the map.
The tables not only show status information about the EAPS domains, network devices, and the EAPS-
related links between devices, they also provide a mechanism to navigate within the map. When you
select a device or a link in a table, that device or link is centered and highlighted on the map. When you
select a domain from the Domains table, that domain is centered and is put into Focus mode.
As with the map views in the EPICenter Topology applet, you can rearrange the position of elements
on the map by dragging icons around, using the Zoom slider or Zoom commands, using the Automatic
Layout or Fit commands.

EAPS Domain and Device Status

The EAPS map shows all devices currently in the EPICenter database, whether or not they are
configured for the EAPS protocol. If a device in the network is not included in the EPICenter database,
it will not appear on the map, even if it is a member of a domain whose other members are shown on
the map.
Domains are identified by their Control VLAN tags: all EAPS-enabled devices that share the same
Control VLAN, as identified by the VLAN tag, are determined to be members of the same Domain.
Thus if two independent EAPS domains in your network use the same Control VLAN tag, EPICenter
will consider them to be a singe EAPS domain.
Initially, the name of the domain is determined by the name used on the first discovered node in the
domain. Through the Domain Details display you can change the name that EPICenter uses to identify
the domain—this does not affect the domain name in the network.
Status is shown on Device Nodes using a set of small icons that appear within the rectangle that
represents the node. (Note that when the map is zoomed out, only the status icons may appear to
represent a device.)
Node status is shown as follows:
Node Reachability: shown as a green triangle (device is reachable) or a red X (unreachable).
