• To collect performance data on a Virtual Fabric-enabled device, use the 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 the same as the Fabric OS user name. Otherwise, the data is not
collected for virtual switches with a non-default Virtual Fabric ID. By default, the admin user
has access to all Virtual Fabrics.
Example of Fabric OS user verification
sw1:FID128:admin> userconfig --show
Account name: admin
Description: Administrator
Enabled: Yes
Password Last Change Date: Unknown

- Make sure I/O is running on the switch to obtain real statistics. To view switch statistics,
use the portperfshow
(FC Ports) or portshow fciptunnel (FCIP tunnels) command.
Example for FC ports
Sprint-65:root> portperfshow 5
Example for FCIP tunnels
Sprint-65:root> portshow fciptunnel ge0 1 -perf
SAN real-time performance data
Real-time performance monitoring enables you to collect data from managed devices in your SAN.
Real-time performance monitoring is only supported on the following managed objects: FC (E_Ports
and F_Ports), GE_Ports, E_Port trunks, 10GE_Ports, managed HBA Ports, managed CNA Ports, and
FCIP tunnels. You can use real-time performance monitoring to configure the following options:
• Select the polling rate from 10 seconds up to 1 minute.
• Select up to 100 ports total from a maximum of 20 devices for graphing performance.
For E_Port trunks, you can select up to 25 trunks (the trunk member [port] count must be
below 100) from a maximum of 20 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.
