Manipulating Topology Views And Maps - Extreme Networks EPICenter Software Installation Manual

Network Topology Views
Link Nodes
For individual links, the information panel displays the following information:
• Status: The status of the link—up, down, partially up (for load-shared links only) or unknown.
Partially up indicates that one or more of the links in the load shared group is down. In this case, all
other links in the load-shared group are considered partially up.
• Type: The link type (speed) —10/100, 1000, or unknown
• Load shared: Whether the link is load shared (yes or no)
In addition, for each link endpoint, the following information is displayed:
• Node: The name of the node that contains the endpoint
• Device: The name of the device represented by the endpoint node
• Port: The device port or slot and port to which the link connects, if known
• Load Shared Ports: The device represented by the endpoint node is not displayed if the port is not
load shared.
• Utilization: The utilization percentage, if RMON is enabled on the device and if RMON statistics are
enabled for this map. The default is that RMON statistics are not enabled for a map. This is updated
regularly, typically every 30 seconds
• Total errors: The total errors, if RMON is enabled on the device and if RMON statistics are enabled
for this map. This is updated regularly, typically every 30 seconds
• VLANs/Ports list: Displays the VLANs configured on that port.
Composite Link Nodes
For composite links, the information panel displays the following information:
• Status: The overall status of the composite link— up, down, partially up, or unknown. Partially up
indicates that some links in the composite are up, some are down.
• Link count: The number of individual links in the composite link.
• Links Status: The number of links up, partially up, down and unknown.
In addition, for each link endpoint, the following information is displayed:
• Endpoint 1 and Endpoint 2: The name of each endpoint node
• Endpoint 1 device and Endpoint 2 device: The device type or each endpoint node
• A table showing the endpoint ports (or slot and port) for each individual link in the composite link,
along with the link status and whether the link is load shared. You may need to move the right side
boundary of the panel to see the last two columns.

Manipulating Topology Views and Maps

You can create new topology views or move elements around on existing maps in a number of ways.
The Topology View applet provides a number of ways to invoke the various commands and functions:
• A series of pull-down menus. All commands and functions can be accessed from these menus
• A set of icons that represent a commonly-used subset of the functions available
