fctrace Description Displays the path from an initiator device port in the fabric to a target device port in the same zone. To trace the path between two initiator ports, you must disable the I/O StreamGuard feature. Use the set config port command to change the IOStreamGuard parameter. Path information includes the following: • Domain IDs • Inbound port name and physical port number • Outbound port name and physical port number Authority None Syntax fctrace [port_source] [port_destination] [hop_count] Operands [port_source] The Fibre Channel port from which to begin the trace. [port_source] can have the following formats: • 6-character hexadecimal device Fibre Channel address (hex). Enter addresses with or without the "0x" prefix. • 16-character hexadecimal world wide port name (WWPN) with the format xx:xx:xx:xx:xx:xx:xx:xx or xxxxxxxxxxxxxxxx. [port_destination] The Fibre Channel port at which to end the trace. [port_destination] can have the following formats: • 6-character hexadecimal device Fibre Channel address (hex).

Command Reference
fctrace
Description
Displays the path from an initiator device port in the fabric to a target device port in the same zone.
To trace the path between two initiator ports, you must disable the I/O StreamGuard feature. Use the
set config port
command to change the
IOStreamGuard
parameter.
Path information includes the following:
Domain IDs
Inbound port name and physical port number
Outbound port name and physical port number
Authority
None
Syntax
fctrace [port_source] [port_destination]
[hop_count]
Operands
[port_source]
The Fibre Channel port from which to begin the trace. [port_source] can have the following
formats:
6-character hexadecimal device Fibre Channel address (hex). Enter addresses with or without
the “0x” prefix.
16-character hexadecimal world wide port name (WWPN) with the format
xx:xx:xx:xx:xx:xx:xx:xx or xxxxxxxxxxxxxxxx.
[port_destination]
The Fibre Channel port at which to end the trace. [port_destination] can have the following
formats:
6-character hexadecimal device Fibre Channel address (hex). Enter addresses with or without
the “0x” prefix.
16-character hexadecimal world wide port name (WWPN) with the format
xx:xx:xx:xx:xx:xx:xx:xx or xxxxxxxxxxxxxxxx.
[hop_count]
Maximum number of hops before stopping the trace. If you omit [hop_count], 20 hops is used.
Examples
The following is an example of the
fctrace
command:
8/20q FC Switch#> fctrace 970400 970e00 hops 5
36 bytes from 0x970400 to 0x970e00, 5 hops max
