portCmd
-f first_ttl
Specifies the starting point for the "time to live" parameter. The default is 1. The command
skips processing for those intermediate gateways that are less than the first_ttl hops. This
operand is optional.
-q service_type
Specifies the type of service in the traceroute request. The default is 0 and service_type
must be an integer from 0 to 255. This operand is optional.
-w wait_time
Sets the time, in milliseconds, to wait for a response to a probe. The default is 5000
milliseconds. The maximum wait time is 9000 milliseconds (9 seconds). This operand is
optional.
-z size
Specifies the size, in bytes, of the trace route packet to use. The default is 64 bytes. In an
IPv4 environment, the ICMP/IP header occupies 28 bytes. In an IPv6 environment, it
occupies 48 bytes. The total size, including ICMP/IP headers (28 or 48 bytes without IP
options), cannot be greater than the IP MTU configured on the interface. This operand is
optional.
-v vlan_id
Specifies the VLAN ID. Values must be in the range between 1 and 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. See the portCfg help page for details on creating a VLAN tag table.
This option is supported on Brocade FX8-24 blade only.
-c L2 Class-of-Service
Specifies Class of Service/Priority, as defined by the IEEE 802.1p specification. Values
must be in the range between 0 and 7. The default value is 0. This operand is optional
with the -v option.
--help
Displays command usage.
--tperf
Determines the path characteristics to a remote host or tunnel destination. The -tperf option
requires two separate Brocade FX8-24 blades to function. One blade plays the role of a
data sink and the other blade plays the role of the data source. TPerf also requires that you
define a tunnel as a TPerf tunnel. Refer to portCfg fciptunnel for more information. This
option is supported on Brocade FX8-24 blade only.
-sink | -source
Designates the switch to function either as a data sink or a data source. This operand is
required.
When -sink is specified, TPerf begins to respond to traffic sent by the switch acting as the
data source. The process continues to run until it is either terminated by user intervention
(Ctrl +C) or, if a value for duration is specified with the -t option, until the process completes
the set time frame.
