Displaying fabric information
The topology display is your primary tool for monitoring a fabric. The graphic window of the topology
display provides status information for switches, inter-switch links, and the Ethernet connection to the
management workstation.
The data window tabs show device, switch, link, and active zone set information. The Active Zoneset data
window shows the zone definitions for the active zone set. See ”Devices data window” on page 48 and
”Switch data window” on page 71 for information about the Devices and Switch data windows.
Fabric status
The fabric updates the topology and faceplate displays by forwarding changes in status to the
management workstation as they occur. You can allow the fabric to update the display status, or you can
refresh the display at any time. To refresh the topology display, choose one of the following:
• Click Refresh.
• Select View > Refresh.
• Press F5.
• Right-click in the background of the topology display, and select Refresh Fabric from the popup menu.
The topology display uses switch and status icons to provide status information about switches, inter-switch
links, and the Ethernet connection. The switch status icons, displayed on the left side of a switch, vary in
shape and color. Switches controlled by an Ethernet Internet Protocol have a colored Ethernet icon
displayed on the right side of the switch. A green Ethernet icon indicates normal operation, yellow
indicates a condition that may require attention to maintain maximum performance, and red indicates a
potential failure. Table 4 shows the different switch icons and their meanings.
