490 Configuring and monitoring FCIP extension services
-S
Operates the WAN tool FCIP port-embedded client in the sender mode. The test endpoint will
generate a traffic stream and report the end-to-end IP path characteristics from this endpoint
toward the receiver endpoint. This option cannot be used with the –R option.
- R
Operates the WAN tool FCIP-port embedded client in the receiver mode. The test endpoint will
accept a connection and traffic stream from the sender This option cannot be used with the -S
option.
-r rate
The committed rate for the data stream in Kb/s. If specified, the traffic generator will be limited
by a traffic shaper. This can be used to characterize the end-to-end IP path performance based
on the data rate to be configured for a tunnel between the same endpoints. If a rate is not
specified, the traffic generator will compete for uncommitted bandwidth.
-z size
The size in bytes for each buffer handed to the TCP layer. If a size is not specified, the maximum
size data buffer will be used based on the outbound IP interface MTU. The size is the only
buffer size that will be handed over to the TCP layer.
-t time
The total time in seconds to run the test traffic stream. If a time is not specified, the test will run
continuously until stopped by typing ctrl-C.
-i interval
The interval in seconds between polling and printing stats. The default is 30 sec. If this time is
greater than the running time (specified by –t), the stats will be printed only once at the
conclusion of the test.
-p port
The TCP port number for the listener endpoint. If a TCP port is not specified, port 3227 is used
(this is next port after ports 3225 and 3226, which are used for the FCIP tunnel connections).
-q diffserv
The DiffServ marking code point (DSCP) for the TCP connection. The value must be an integer
in the range of 0 to 63. The default value is 0. This operand is optional. Before configuring
DSCP settings, determine if the IP network you are using implements PHB, and consult with the
network administrator to determine the appropriate DSCP values.
-v vlan_id
The VLAN ID. Values must be in the range of 1 - 4094. There is no default value. Note that a
VLAN tag entry must exist on the local and remote sides prior to issuing the -v option. A VLAN
Tag table entry will be dynamically maintained by the ipperf application.
-c L2_Cos
The Class of Service/Priority as defined by IEEE 802.1p. Values must be in the range between
0 and 7. The default is 0. This operand is optional with the -v option
Testing a connection
The
portCmd ping
command tests the connection between the IP address of a local Ethernet port (ge0
or ge1) and a destination IP address. If you want to use this command to test a VLAN connection when you
do not have an active FCIP tunnel, you must manually add entries to the VLAN tag table on both the local
and remote sides of the route, using
portCfg vlantag
command.

ping [slot]/ge0|ge1 -s source_ip -d destination_ip [-n num_requests] [-q
diffserv] [-t ttl] [-w wait_time] [-z size] [-v vlan_id] [-c L2_Cos]
where:
slot
The number of a slot in an HP StorageWorks 4/256 SAN Director and an HP StorageWorks
DC SAN Backbone Director or HP StorageWorks DC04 SAN Director Switch enterprise-class
platforms that contains an FR4-18i blade. This parameter does not apply to the stand-alone HP
StorageWorks 400 Multi-Protocol Router.
ge0|ge1
The Ethernet port used by the tunnel (ge0 or ge1)
-s source_ip
The source IP interface that originates the ping request.
-d destination_ip
The destination IP address for the ping request.
-n num-requests
Generates a specified number of ping requests. The default is 4.
-q diffserv
The DiffServ QoS. The default is 0 (zero). The value must be an integer in the range from 0
through 255.
-t ttl
The time to live (TTL) for the ping packets. The ttl is decremented every time a router handles the
packet. If TTL reaches zero, the packet is discarded. This prevents ping packets from circulating
forever and potentially flooding the network. The default value is 100.
