• To collect performance on a Virtual Fabric enabled device, use the admin> userconfig
--show
command to make sure the Fabric OS user has access to all the Virtual Fabrics. Make
sure that the SNMPv3 user name is same as the Fabric OS user name. Otherwise, the data is
not collected for virtual switches with a non-default VF ID. By default the
admin user has
access to all Virtual Fabrics.

number> <tunnel no> -perf
(FCIP tunnels) command.

Real-time performance data
Real-time performance enables you to collect data from managed devices in your SAN. Real-time
performance is only supported on the following managed objects: FC (E_ and F_ports), GE_ports,
10GE_ports, Managed HBA Ports, and FCIP tunnels. You can use real-time performance to
configure the following options:
• Select the polling rate from 10 seconds up to 1 minute.
• Select up to 32 ports total from a maximum of 10 devices for graphing performance.
NOTE
Virtual Fabric logical ISL ports are not included in performance collection.
• Choose to display the same Y-axis range for both the Tx MB/Sec and Rx MB/Sec measure
types for easier comparison of graphs.
