Setting Up ISL Trunking in a Fabric Example 2. The following example shows traffic flowing through a trunking group of three ports, with one of the links failing after the second reading, causing redistribution of traffic over the remaining two links in the group. switch:admin> portperfshow 0 1 2 3 4 5 6 7 Total 0 0 0 0 0 145m 144m 145m 434 0 0 0 0 0 144m 143m 144m 431 0 0 0 0 0 162m 0 162m 324 0 0 0 0 0 186m 0 186m 372 0 0 0 0 0 193m 0 192m 385 0 0 0 0 0 202m 0 202m 404 0 0 0 0 0 209m 0 209m 418 switch:admin> For more details about the portperfshow command, refer to the HP StorageWorks Fabric OS Version 3.1.x/4.1.x Reference Guide. Using Performance Monitoring to Gather Traffic Data Performance Monitoring can be used to monitor traffic flow and to view the impact of different fabric configurations on performance. For instructions on using Performance Monitoring, refer to the HP StorageWorks Advanced Performance Monitoring Version 3.1.x/4.1.x User Guide. Using Fabric Watch to Gather Traffic Data Fabric Watch can be used to monitor traffic flow through specified ports on the switch and send alerts when the traffic exceeds or drops below configurable thresholds. This allows the administrator to monitor changes in traffic patterns and adjust the fabric design accordingly, by adding, removing, or reconfiguring ISLs and trunking groups. For instructions on configuring Fabric Watch thresholds and alerts, refer to the HP StorageWorks Fabric Watch Version 3.1.x/4.1.x User Guide. 30 ISL Trunking Version 3.1.x/4.1.x User Guide
