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 collaboratorC function example command "dump_forward_entries"
Switch Event forwarding configuration command (dump_forward_entries)
is a command to dump event forwarding entries of
Switch Manager and Switch Daemons.
Following switch event types can be configured by this command:
- vendor
- packet_in
- port_stat
- state_notify
This command is a simple usage example for C version of switch event forwarding API.
C version API is defined as a group of functions declared in event_forward_interface.h.
These functions are used in topology manager to
add itself to packet_in forwarding entry of all existing switch daemons and
switch manager to receive LLDP packets.
By adding and removing entry for 'topology' from some switches, it is possible to make
topology manager to map only a subset of the switches managed by trema.
Please see README.md for general notes on switch event forwarding API.
- Background
-
- Given
- I cd to "../../src/examples/switch_event_config/"
- And
- I compile "dump_forward_entries.c" into "dump_forward_entries"
- Scenarios
-
- dump_forward_entries Usage
- Dump Switch Manager's event forwarding entries for each event type
- Dump Switch Daemon's event forwarding entries for each event type on each switch
- dump_forward_entries Usage
-
- When
-
I successfully run
trema run './dump_forward_entries -h' - Then
-
the output should contain:
Dump OpenFlow Switch Manager/Daemon event forward entries. Switch Manager: dump_forward_entries -m -t EVENT_TYPE Switch Daemon : dump_forward_entries -s SWITCH_DPID -t EVENT_TYPE EVENT_TYPE: -t, --type={vendor,packet_in,port_status,state_notify} Specify event type.
- Dump Switch Manager's event forwarding entries for each event type
-
- Given
-
a file named "nw_dsl.conf" with:
vswitch { datapath_id 0x1 } vswitch { datapath_id 0x2 } - And
-
I successfully run
trema run ../repeater_hub/repeater-hub.rb -c nw_dsl.conf -d - And
- wait until "RepeaterHub" is up
- When
-
I successfully run
trema run './dump_forward_entries -m -t type' - Then
- the output should contain "Current service name list:"
- And
- the output should contain " RepeaterHub"
Examples: type vendor packet_in port_status state_notify - Dump Switch Daemon's event forwarding entries for each event type on each switch
-
- Given
-
a file named "nw_dsl.conf" with:
vswitch { datapath_id 0x1 } vswitch { datapath_id 0x2 } - And
-
I successfully run
trema run ../repeater_hub/repeater-hub.rb -c nw_dsl.conf -d - And
- wait until "RepeaterHub" is up
- When
-
I successfully run
trema run './dump_forward_entries -s switch -t type' - Then
- the output should contain "Current service name list:"
- And
- the output should contain " RepeaterHub"
Examples: switch type 0x1 vendor 0x1 packet_in 0x1 port_status 0x1 state_notify 0x2 vendor 0x2 packet_in 0x2 port_status 0x2 state_notify
