Using Traceroute

The portCmd traceroute command traces routes from a local Ethernet port to a destination IP
address. If you want to use this command to trace a route across a VLAN 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.
portCmd
first_ttl]
[-q diffserv] [-w timeout] [-z size] [-v vlan_id] [-c L2_Cos]
Where:
slot
ge<n>|xge<n>
-s source_ip
-d destination_ip
-h max_hops
-f first_ttl
-q diffserv
-w wait_time
-z size
-v vlan_id
-c L2_Cos
The following example traces the route between IP addresses 192.168.10.1 and 192.168.20.1
over VLAN 10.
portcmd --traceroute 8/ge0 -s 192.168.10.1 -d 192.168.20.1 -v 10

The number of a slot in a 48000 director and a Brocade DCX or DCX-4S
enterprise-class platforms that contains an FR4-18i blade. This parameter
does not apply to the stand-alone Brocade 7500 Extension Switch.
The Ethernet port used by the tunnel.
The source IP interface that originates the traceroute request.
The destination IP address for the traceroute request.
The maximum number of IP router hops allowed for the outbound probe
packets. If this value is exceeded, the probe is stopped. The default is 30.
The initial time to live value for the first outbound probe packet. The default
value is 1.
The DiffServ QoS. The default is 0 (zero). The value must be an integer in the
range from 0 through 255 (7500 switch and FR4-18i blade only).
The time to wait for the response of each ping request. This parameter is
specified in milliseconds and the default value is 5000 milliseconds (5 sec).
The maximum allowed wait time for ping is 29000 milliseconds (29 sec).
The size in bytes of the ping packet to use. The total size cannot be greater
than the configured MTU size. The default size is 64 bytes.
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 (7500 switch and FR4-18i blade only).
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 (7500 switch and FR4-18i blade only).
