Adding a monitor to an F_Port master port 1. Connect to the switch and log in using an account assigned to the admin role. 2. Enter the perfAddEEMonitor command. switch:admin> perfaddeemonitor 4 0x010400 0x020800 Adding monitor to the master port of the F-Port Trunk. where 4 is a slave port of the F_Port Trunk. If you attempt to install a monitor on a slave port of an F_Port trunk and the same monitor is already installed on the corresponding master, the following message is displayed. switch:admin> perfaddeemonitor 4 0x010400 0x020800 Similar monitor already exists on the master port of the F-Port Trunk where 4 is a slave port of the F_Port Trunk. Fabric Watch allows you to monitor traffic flow through specified ports on the switch and send alerts when the traffic exceeds or drops below configured thresholds. Fabric Watch monitors only the trunk masters and not the slave ports. Fabric OS CLI allows you to display throughput information for all ports on the switch. Data is displayed in 8 or 16 columns, one column per port plus one column that displays the total for these ports. Results display every second or over the specified interval, until Enter, Ctrl-C, or Ctrl-D is pressed. See the Fabric OS Command Reference for additional information. Displaying port throughput performance information for all ports on the switch 1. Connect to the switch and log in using an account assigned to the admin role. 2. Enter the portPerfShow command. portperfshow [interval] where the interval is the number of seconds between each data-gathering sample (the default is one sample every second). 3. Record the traffic flow for each port participating in an ISL. 4. Repeat step 1 through step 3 for each switch in the fabric until all ISL traffic flow is captured. In a large fabric, it may be necessary only to identify and capture the key ISLs. However, you may want to continue this process throughout the day (or an entire work cycle) to capture varying traffic patterns under different conditions. The following example shows a switch without trunking, and indicates that ports 0 through 2 are underutilized and ports 4 and 5 are congested: switch:admin> portperfshow 0 1 2 3 4567 Total 0 0 0 145m204m202m0168m 719 0 0 0 145m206m208m0186m 745 Fabric OS 6.2 administrator guide 439
