NAME
pong — send Fibre Channel Light Weight Protocol Echo Request packet
SYNOPSIS
/opt/fc/bin/pong
N_port_address
DESCRIPTION
The
pong
command
sends
FC_LWP Echo Request
packets to a well known FC_LWP protocol port number at the specified
N_port_address
once per second.
Information from each packet that is echoed back to the sending N_port
is written to the standard output.
FC_LWP Echo Request are
datagrams packets which have an FC-PH header and an FC_LWP header
which specifies routing to the FC_LWP protocol port, followed by a
FC_LWP protocol port Echo request code.
Pad bytes are used to fill out the packet to the fixed size of 64 bytes.
Pong
sends one datagram packet per second until interrupted.
No output is produced if there are no responses.
This command is intended for use in testing, managing,
and measuring network performance for FC_LWP.
It should be used primarily to isolate network failures, and validate
simple connectivity.
