Portcmd - Brocade Communications Systems A7533A - Brocade 4Gb SAN Switch Base Command Reference Manual

portCmd

Diagnoses intelligent ports.
Synopsis portcmd action [slot/]geport arguments
Description Use this command to invoke the end-to-end IP path performance (ipperf) characterization feature,
or to ping or trace route to a destination IP host from an intelligent GbE port.
Notes Virtual LAN (VLAN) tagging is supported on the Brocade FR4-18i and all 7500 platforms that run
Fabric OS v6.0.0 or later. To ensure that test traffic traverses the same path as real FCIP traffic
would, portCmd supports the VLAN settings as an option. Note that a VLAN tag entry must exist
prior to issuing the --ping or --traceroute commands; this includes both the local and remote
sides. A VLAN Tag table entry is dynamically maintained by the ipperf application.
End-to-end path characterization is not supported if there exists an IPSec-enabled tunnel using the
same source/local IP address.
The execution of this command is subject to Admin Domain restrictions that may be in place. Refer
to chapter 1, "Understanding Admin Domain Restrictions" and Appendix A, "Command Availability"
for details.
Operands This command has the following operands:

--ipperf
Fabric OS Command Reference

For bladed systems only, specify the slot number of the port to be configured,
followed by a slash (/).
Specifies the port number of the GbE port on the blade.
Determines the path characteristics to the remote host. Valid arguments and
their values include:
-s src_ip Specifies the local IP address to use for sourcing the probe packets. ipperf
will not start if there exists an IPSec-enabled tunnel using the same source IP
address. IPv6 addresses are supported.
-d dst_ip Specifies the destination IP address to which to probe the IP router path. IPv6
addresses are supported.
-S Specifies the source mode to initiate the TCP connection. The source
end-point generates a traffic stream and reports the end-to-end IP path
characteristics from this end-point to the receiver end-point sink.
-R Specifies the sink mode to accept the new connection. The end-to-end path
characteristics are not reported.
-i interval Specifies the intervals between polling and displaying statistics, in seconds. If
the duration is less than -t running_time, the statistics displays only once, at
the conclusion of the test. This operand is optional.
-p port Specifies the TCP port number for the listener end-point. This operand is
optional.
-q diffserv Specifies the DSCP (DiffServ Code Point) marking used for the TCP
connection. This operand accepts values between 0 and 63 (inclusive). The
default value is 0.
