2. Configure the sender test endpoint using a similar CP CLI.
The following example shows the results of the performance analysis for slot 8, port ge0:

The syntax for invoking the sender test endpoint using
FR4-18i is as follows:
portcmd --ipperf 8/ge0 -s 192.168.255.100 -d 192.168.255.10 –S
The interval specified with the portCmd
or the default, 30 seconds.
The current running test total time (in seconds) for the last
issued.
The bandwidth measured in the last interval. Bandwidth is defined as the
total packets and bytes sent. BW represents what the FCIP tunnel / FC
application sees for throughput rather than the Ethernet on-the-wire bytes.
The weighted bandwidth currently with a gain of 50 percent.
The number of TCP retransmits. This number is an average rate over the last
display interval.
The TCP smoothed round-trip time (RTT) and variance estimate in
milliseconds.
The path MTU. This is the largest IP-layer datagram that can be transmitted
over the end-to-end path without fragmentation. This value is measured in
bytes and includes the IP header and payload. Note: There is limited support
for black hole PMTU detection. If the Jumbo PMTU (anything over 1500) does
not work,
lower PMTU of 1260 (the minimum PMTU supported for FCIP tunnels). If
1260 also fails,
hole PMTU detection the BW, WBW, Loss and PMTU values printed may not
be accurate.
