To add a collaborator to this project you will need to use the Relish gem to add the collaborator via a terminal command. Soon you'll be able to also add collaborators here!
More about adding a collaboratorsend_packets command
In order to send/receive packets between virtual hosts
As a developer using Trema
I want to execute "trema send_packets" command
- Background
-
- Given
-
a file named "learning_switch.conf" with:
vswitch("learning") { datapath_id 0xabc } vhost("host1") { ip "192.168.0.1" } vhost("host2") { ip "192.168.0.2" } link "learning", "host1" link "learning", "host2" - And
-
I run
trema run ../../src/examples/learning_switch/learning-switch.rb -c learning_switch.conf -d
- Scenarios
-
- Sending packets
-
- When
-
I run
trema send_packets --source host1 --dest host2 --n_pkts=2 - And
-
I run
trema send_packets --source host2 --dest host1 --n_pkts=1 - Then
-
the total number of tx packets should be:
host1 host2 2 1 - And
-
the total number of rx packets should be:
host1 host2 1 2
- unknown host error (--source)
-
- When
-
I run
trema send_packets --source NO_SUCH_HOST --dest host2 - Then
-
the output should contain:
unknown host: NO_SUCH_HOST
- unknown host error (--dest)
-
- When
-
I run
trema send_packets --source host1 --dest NO_SUCH_HOST - Then
-
