8. AIX
Hi Members,
To check the large pages configuration in AIX, this is what we use:
"nmon" followed by "Enter Key" followed by "L" (without any double quotes)
Is there any way that we can achieve the same in a single command.

arping
ARPING(8) System Manager's Manual: iputils ARPING(8)
NAME
arping - send ARP REQUEST to a neighbour host
SYNOPSIS
arping [-AbDfhqUV] [-c count] [-w deadline] [-s source] -I interface destination
DESCRIPTION
Ping destination on device interface by ARP packets, using source address source.
OPTIONS
-A The same as -U, but ARP REPLY packets used instead of ARP REQUEST.
-b Send only MAC level broadcasts. Normally arping starts from sending broadcast, and switch to unicast after reply received.
-c count
Stop after sending count ARP REQUEST packets. With deadline option, arping waits for count ARP REPLY packets, until the timeout
expires.
-D Duplicate address detection mode (DAD). See RFC2131, 4.4.1. Returns 0, if DAD succeeded i.e. no replies are received
-f Finish after the first reply confirming that target is alive.
-I interface
Name of network device where to send ARP REQUEST packets.
-h Print help page and exit.
-q Quiet output. Nothing is displayed.
-s source
IP source address to use in ARP packets. If this option is absent, source address is:
o In DAD mode (with option -D) set to 0.0.0.0.
o In Unsolicited ARP mode (with options -U or -A) set to destination.
o Otherwise, it is calculated from routing tables.
-U Unsolicited ARP mode to update neighbours' ARP caches. No replies are expected.
-V Print version of the program and exit.
-w deadline
Specify a timeout, in seconds, before arping exits regardless of how many packets have been sent or received. In this case arping
does not stop after count packet are sent, it waits either for deadline expire or until count probes are answered.

AUTHOR
arping was written by Alexey Kuznetsov <kuznet@ms2.inr.ac.ru>. It is now maintained by YOSHIFUJI Hideaki <yoshfuji@skbuff.net>.
SECURITY
arping requires CAP_NET_RAW capability to be executed. It is not recommended to be used as set-uid root, because it allows user to modify
ARP caches of neighbour hosts.
AVAILABILITY
arping is part of iputils package and the latest versions are available in source form at http://www.skbuff.net/iputils/iputils-cur-
rent.tar.bz2.
