This example shows invoking fctrace using the device alias of the destination N port.
switch# fctrace device-alias disk1 vsan 1

fcping
The fcping feature verifies reachability of a node by checking its end-to-end connectivity. You can invoke
the fcping feature by providing the FC ID, the destination port WWN, or the device alias information.
To perform a fcping operation, perform this task:
Procedure
switch# fcping {device-alias aliasname | fcid {fc-port | domain-controller-id} | pwwn pwwn-id} vsan vsan-id
[[count] [ number ] [[timeout] [ value ] [[usr-priority] [ priority ]]]]
The device-alias option specifies the device alias name. The fcid specifies the FCID of the destination N port,
with the format 0xhhhhhh. The domain-controller-id option verifies connection to the destination switch. The
pwwn specifies the PWWN of the destination N port, with the format hh:hh:hh:hh:hh:hh:hh:hh. The vsan
option specifies a VSAN ID.
The last three are optional: The count option specifies the number of frames to send in a range of 0 to
2147483647. A value of 0 sends forever. By default, five frames are sent. The timeout option specifies the
timeout value in seconds. The range is 1 to 10. The usr-priority option specifies the priority the frame receives
in the switch fabric.
This example shows invoking fcping for the specified FCID of the destination:
switch# fcping fcid 0xd70000 vsan 1
28 bytes from 0xd70000 time = 730 usec
28 bytes from 0xd70000 time = 165 usec
28 bytes from 0xd70000 time = 262 usec
28 bytes from 0xd70000 time = 219 usec
28 bytes from 0xd70000 time = 228 usec
5 frames sent, 5 frames received, 0 timeouts
Round-trip min/avg/max = 165/270/730 usec
This example shows invoking fcping using the count option:
switch# fcping fcid 0xd70000 vsan 1 count 10
28 bytes from 0xd70000 time = 730 usec
28 bytes from 0xd70000 time = 165 usec
28 bytes from 0xd70000 time = 262 usec
28 bytes from 0xd70000 time = 219 usec
28 bytes from 0xd70000 time = 228 usec
28 bytes from 0xd70000 time = 230 usec
28 bytes from 0xd70000 time = 230 usec
28 bytes from 0xd70000 time = 225 usec
28 bytes from 0xd70000 time = 229 usec
28 bytes from 0xd70000 time = 183 usec
10 frames sent, 10 frames received, 0 timeouts
Round-trip min/avg/max = 165/270/730 usec
This example shows invoking fcping with a timeout value:
switch# fcping fcid 0xd500b4 vsan 1 timeout 10
28 bytes from 0xd500b4 time = 1345 usec
...
5 frames sent, 5 frames received, 0 timeouts
Round-trip min/avg/max = 340/581/1345 usec
