WAN performance analysis tools
WAN analysis tools are designed to test connections, trace routes, and estimate the end-to-end IP
path performance characteristics between a pair of Brocade FCIP port endpoints. These tools are
available as options on the portCmd command. The following options are available:
• portCmd --Tperf—Used only with the 7800 switch and FX8-24 blade, tperf is a tunnel test tool
that generates and sends test data over an FCIP tunnel to determine the characteristics and
reliability of the IP network used by the tunnel at the FCIP circuit level.
• portCmd --ipperf—Used only with the FR4-18i blade, ipperf is used to analyze end-to-end IP
path performance between a pair of FCIP ports.
• portCmd --ping—Tests connections between a local Ethernet port and a destination IP
address.
• portCmd --traceroute—Traces routes from a local Ethernet port to a destination IP address.
• portShow fcipTunnel -perf—Displays performance statistics generated from the WAN analysis.
The tperf option
NOTE
The Tperf option is for 7800 switches and FX8-24 blades.
Tperf operates with a pair of 7800 switches or FX8-24 blades. One switch or blade plays the role of
a data sink and the other switch or blade plays the role of the data source.
To use Tperf, you must first create an FCIP tunnel with at least one circuit or modify an existing
tunnel using the Tperf flag -T. As with any FCIP tunnel, this must be done on both switches. The
following commands create a Tperf-enabled tunnel with a committed rate of 10000.
portcfg fciptunnel 16 create 192.168.10.1 192.168.10.2 10000 -T
portcfg fciptunnel 16 create 192.168.10.2 192.168.10.1 10000 -T
Tperf will test single and multiple circuit tunnels. Tperf also tests the different priority connections
that are provided by an FCIP Tunnel. When a Tperf--enabled tunnel is operative, it is not an active
VE_Port. Fabrics will not merge over an operative FCIP Tperf tunnel. To determine if the Tperf
tunnel is up, issue the following command:
switch:admin> portshow fciptunnel all -c
