Setting for Examples

This was done in a two-machine LANforge cluster, the manager named jedtest and the second resource named kedtest. The CLI output of these CLI commands has been discarded as well as any show_port commands.

The show_port commands are useful for inspecting the results of previous commands. Often there is useful wait before issuing the show_port command to allow processing time on the manager. Please inspect the scripts in the /home/lanforge/scripts directory for how and when they tend to sleep.

These commands are also found in the /home/lanforge/DB/DFLT directory files. You cannot run those DB files directly, because they are executed in certain order. However, you can grep for connection- and station-names in those files to find results of GUI commands.

Creating Stations

Using Open Authentication

This station is created with DHCP enabled. That is controlled via flags that are descibed in the add_sta command.

Shell script:

./lf_vue_mod.sh --mgr jedtest --resource 2 --create_sta --name sta100 --radio wiphy0 --security open --ssid jedtest

Perl script:

./lf_associate_ap.pl --mgr jedtest --resource 2 --quiet yes --action add --radio wiphy0 --security open --ssid jedtest --passphrase --first_sta sta100 --first_ip DHCP --num_stations 1

CLI command:

set_wifi_radio 1 2 wiphy0 NA -1 NA NA NA NA NA NA NA NA 0x1 NA
add_sta 1 2 wiphy0 sta100 0 jedtest NA [BLANK] AUTO NA 00:0e:8e:8d:8d:e9 8 NA NA NA NA NA 0
set_port 1 2 sta100 0.0.0.0 255.255.0.0 0.0.0.0 NA 2147483648 00:0e:8e:8d:8d:e9 NA NA NA 8405038 1000 NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NONE

Using WPA2 Authentication

This station is created with DHCP enabled. That is controlled via flags that are descibed in the add_sta command.

Shell script:

 $ ./lf_vue_mod.sh --mgr jedtest --resource 2 --create_sta --name sta200 \
  --radio wiphy1 --security wpa2 --ssid jedtest --passphrase jedtest1 \
  --log_cli /tmp/clilog.txt

Perl script:

./lf_associate_ap.pl --mgr jedtest --resource 2 \
  --action add --radio wiphy1 --security wpa2 --ssid jedtest \
  --passphrase jedtest1 --first_sta sta200 --first_ip DHCP --num_stations 1

CLI command:

set_wifi_radio 1 2 wiphy1 NA -1 NA NA NA NA NA NA NA NA 0x1 NA
add_sta 1 2 wiphy1 sta200 1024 jedtest NA jedtest1 AUTO NA 00:0e:8e:6f:01:62 8 NA NA NA NA NA 1024
set_port 1 2 sta200 0.0.0.0 255.255.0.0 0.0.0.0 NA 2147483648 00:0e:8e:6f:01:62 NA NA NA 8405038 1000 NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NONE

Static IP Addresses

Here is an example of creating a virtual station with a static address: 10.26.2.14/255.255.254.0

Shell Script:

--

Perl Script:

./lf_associate_ap.pl --mgr jedtest --resource 2 --action add --radio wiphy1 --first_sta sta203 --first_ip 10.26.2.4 --netmask 255.255.254.0 --ssid jedtest --security wpa2 --passphrase jedtest1 --num_stations 1 --wifi_mode abgnAC --log_cli /tmp/clilog.txt

CLI Command:

set_wifi_radio 1 2 wiphy1 NA -1 NA NA NA NA NA NA NA NA 0x1 NA
show_port 1 2 wiphy1
add_sta 1 2 wiphy1 sta203 1024 jedtest NA jedtest1 AUTO NA 00:0e:8e:63:50:62 8 NA NA NA NA NA 1024
set_port 1 2 sta100 10.26.2.4 255.255.254.0 0.0.0.0 NA 0 00:0e:8e:63:50:62 NA NA NA 8388654 1000 NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NONE

Station DHCP IP Address

For the station to gain a DHCP IP address, you have to admin-up the station.

Creating a Station with a MAC Address Pattern

The lf_associate_ap script contains logic that parses a MAC address pattern and produces new MAC addresses. This is not a feature of the LANforge Manager. Your CLI calls to the LANforge manager will not parse the mask.

The pattern nomenclature of the LANforge GUI can also be used when specifying a MAC address for stations:

xx

keep parent radio octet

*

randomize this octet

00 - ff

assign this value to the octet

Shell script:

--

Perl script:

./lf_associate_ap.pl --mgr jedtest --resource 2 --action add --radio wiphy1 --first_sta sta205 --first_ip 10.26.2.4 --netmask 255.255.254.0 --ssid jedtest --security wpa2 --passphrase jedtest1 --num_stations 1 --mac-pattern '4e:xx:xx:xx:*:01' --log_cli /tmp/clilog.txt

CLI command:

set_wifi_radio 1 2 wiphy1 NA -1 NA NA NA NA NA NA NA NA 0x1 NA
show_port 1 2 wiphy1
add_sta 1 2 wiphy1 sta205 1024 jedtest NA jedtest1 AUTO NA 4e:0e:8e:43:f1:01 8 NA NA NA NA NA 1024
set_port 1 2 sta205 10.26.2.4 255.255.254.0 0.0.0.0 NA 0 4e:0e:8e:43:f1:01 NA NA NA 8388654 1000 NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NONE

Admin Down

Shell script:

./lf_vue_mod.sh --mgr jedtest --resource 2 --down --name sta200 --log_cli /tmp/clilog.txt --quiet 1

Perl script:

./lf_portmod.pl --manager jedtest --card 2 --port_name sta200 --set_ifstate down

CLI command:

rm_vlan 1 2 sta100

Creating Connections and Running Traffic

LANforge can create Layer-3 and Layer 4-7 connections using the lf_vue_mod.sh script. When connections are created, they exist in a stopped state. Connections can then have their state changed to RUNNING to start traffic.

Starting and Stopping Traffic

Layer-3 and Layer 4-7 connections both subject to the states STOPPED, RUNNING, and QUIECSE.

Shell script:

./lf_vue_mod.sh --mgr jedtest --start_cx --name tcp200 --log_cli /tmp/clilog.txt --quiet 1

./lf_vue_mod.sh --mgr jedtest --stop_cx --name tcp200 --log_cli /tmp/clilog.txt --quiet 1

Perl script:

./lf_firemod.pl --mgr jedtest --action do_cmd --cmd "set_cx_state default_tm tcp200 RUNNING"

./lf_firemod.pl --mgr jedtest --action do_cmd --cmd "set_cx_state default_tm tcp200 STOPPED"

CLI commands:

set_cx_state default_tm tcp200 RUNNING

set_cx_state default_tm tcp200 STOPPED

Create a Layer 3 TCP Connection

Shell script:

./lf_vue_mod.sh --mgr jedtest --resource 2 --create_cx --name tcp200 --tcp --sta sta200 --port eth1 --bps 1000000 --log_cli /tmp/clilog.txt --quiet 1

Perl script:

./lf_firemod.pl --mgr jedtest --resource 2 --action create_endp --endp_name tcp200-A --speed 1000000 --endp_type lf_tcp --port_name sta200
./lf_firemod.pl --mgr jedtest --resource 2 --action create_endp --endp_name tcp200-B --speed 1000000 --endp_type lf_tcp --port_name eth1
./lf_firemod.pl --mgr jedtest --resource 2 --action create_cx --cx_name tcp200 --cx_endps tcp200-A,tcp200-B

CLI commands:

add_endp tcp200-A 1 2 sta200 lf_tcp -1 NA 1000000 1000000 NA -1 -1 increasing NO NA 0 0
set_endp_report_timer tcp200-A 5000
add_endp tcp200-B 1 2 eth1 lf_tcp -1 NA 1000000 1000000 NA -1 -1 increasing NO NA 0 0
set_endp_report_timer tcp200-B 5000
add_cx tcp200 default_tm tcp200-A tcp200-B
set_cx_report_timer default_tm tcp200 5000 NA 

Create a Layer 3 UDP Connection

Shell script:

./lf_vue_mod.sh --mgr jedtest --resource 2 --create_cx --name upd200 --udp --sta sta200 --port eth1 --bps 2000000 --log_cli /tmp/clilog.txt --quiet 1

Perl script:

./lf_firemod.pl --mgr jedtest --resource 2 --log_cli /tmp/clilog.txt --quiet 1 --action create_endp --endp_name udp200-A --speed 2000000 --endp_type lf_udp --port_name sta200
./lf_firemod.pl --mgr jedtest --resource 2 --log_cli /tmp/clilog.txt --quiet 1 --action create_endp --endp_name udp200-B --speed 2000000 --endp_type lf_udp --port_name eth1
./lf_firemod.pl --mgr jedtest --resource 2 --log_cli /tmp/clilog.txt --quiet 1 --action create_cx --cx_name udp200 --cx_endps udp200-A,udp200-B

CLI commands:

add_endp udp200-A 1 2 sta200 lf_udp -1 NA 2000000 2000000 NA -1 -1 increasing NO NA 0 0
set_endp_report_timer udp200-A 5000

set_endp_report_timer udp200-B 5000
add_cx udp200 default_tm udp200-A udp200-B
set_cx_report_timer default_tm udp200 5000 NA

Create a Layer 4-7 Web Connection

Layer 4-7 connections are created with a one-sided technique, the curl command always operates on the A-side and the B-side is unmanaged. The endpoint and connection naming does not follow the Layer-3 convention.

Shell script:

./lf_vue_mod.sh --mgr jedtest --resource 2 --create_l4 --name yh200 --sta sta200 --url http://www.yahoo.com/ --utm 2400 --log_cli /tmp/clilog.txt --quiet 1

Perl script:

Commands are set using lf_firemod.pl --action do_cmd --cmd ...

CLI commands:

add_l4_endp yh200 1 2 sta200 l4_generic 0 10000 2400 'dl http://www.yahoo.com/ /dev/null' NA NA ca-bundle.crt NA 0 0 60 0 512   0.0.0.0
