AIX Networking Commands

1) How can I display or set values for network parameters?

The no command sets or displays current or next boot values for network tuning parameters.

2) How do I get the IP address of my machine?

Type one of the following:

ifconfig -a host Fully_Qualified_Host_Name

For example, type host cyclop.austin.ibm.com.

3) How do I identify the network interfaces on my server?

Either of the following two commands will display the network interfaces:

lsdev -Cc if

ifconfig -a

To get information about one specific network interface, for example, tr0, run the command:

ifconfig tr0

4) How do I activate a network interface?

To activate the network interface tr0, run the command:

ifconfig tr0 up

5) How do I deactivate a network interface?

For example, to deactivate the network interface tr0, run the command:

ifconfig tr0 down

6) How do I display routing table, interface, and protocol information?

To display routing table information for an Internet interface, type:

netstat -r -f inet

To display interface information for an Internet interface, type:

netstat -i -f inet

To display statistics for each protocol, type:

netstat -s -f inet

7) How do I record packets received or transmitted?

To record packets coming in and going out to any host on every interface, enter:

iptrace /tmp/nettrace

The trace information is placed into the /tmp/nettrace file.

To record packets received on an interface en0 from a remote host airmail over the telnet port, enter:

iptrace -i en0 -p telnet -s airmail /tmp/telnet.trace

The trace information is placed into the /tmp/telnet.trace file.

AIX Workload partitions commands

1) How do I create a workload partition?

To create a workload partition named temp with the IP Address xxx.yyy.zzz.nnn, type:

mkwpar -n temp -N address= xxx.yyy.zzz.nnn

To create a workload partition with the specification file wpar1.spec, type:

mkwpar -f /tmp/wpar1.spec

2) How do I create a new specification file for an existing workload partition wpar1?

To create a specification file wpar2.spec for an existing workload partition wpar1, type:

mkwpar -e wpar1 -o /tmp/wpar2.spec -w

3) How do I start a workload partition?

To start the workload partition called temp, type:

startwpar temp

4) How do I stop a workload partition?

To stop the workload partition called temp, type:

stopwpar temp

5) How do I view the characteristics of workload partitions?

To view the characteristics of all workload partitions, type:

lswpar Name State Type Hostname Directory --------------------------------------------------------------------------------- bar A S bar.austin.ibm.com /wpars/bar foo D S foo.austin.ibm.com /wpars/foo trigger A A trigger /

6) How do I log in to a workload partition?

To log in to the workload partition named wpar1 as user foo, type:

clogin wpar1 -l foo

7) How do I run a command in a workload partition?

To run the /usr/bin/ps command as user root in a workload partition named howdy, type:

clogin howdy -l root /usr/bin/ps

8) How do I remove a workload partition?

To remove the workload partition called temp, type:

rmwpar temp

To stop and remove the workload partition called temp preserving data on its file system, type:

rmwpar -p -s temp

Note: Workload Partitions (WPARs), a set of completely new software-based system virtualization features, were introduced in IBM AIX Version 6.1.

AIX Performance monitoring tools

1) How do I display virtual memory statistics?

To display a summary of the virtual memory statistics since boot, type:

vmstat

To display five summaries at 2-second intervals, type:

vmstat 2 5

To display a summary of the statistics for all of the workload partitions after boot, type:

vmstat -@ ALL

To display all of the virtual memory statistics available for all of the workload partitions, type:

vmstat -vs -@ ALL

2) How do I display statistics for all TTY, CPU, and Disks?

To display a single set of statistics for all TTY, CPU, and Disks since boot, type:

iostat

To display a continuous disk report at 2-second intervals for the disk with the logical name disk1, type:

iostat -d disk1 2

To display 6 reports at 2-second intervals for the disk with the logical name disk1, type:

iostat disk1 2 6

To display 6 reports at 2-second intervals for all disks, type:

iostat -d 2 6

To display only file system statistics for all workload partitions, type:

iostat -F -@ ALL

To display system throughput of all workload partitions along with the system, type:

iostat -s -@ ALL

3) How do I display detailed local and remote system statistics?

Type the following command:

topas

To go directly to the process display, enter:

topas -P

To go directly to the logical partition display, enter:

topas -L

To go directly to the disk metric display, enter:

topas -D

To go directly to the file system display, enter:

topas -F

4) How do I report system unit activity?

Type the following command:

sar

To report processor activity for the first two processors, enter:

sar -u -P 0,1

This produces output similar to the following:

cpu %usr %sys %wio %idle 0 45 45 5 5 1 27 65 3 5
