Verify add-host-intent
Steps:
- Discover hosts
- Add host intents
- Check intents
- Verify flows
- Ping hosts
- Reroute
- Link down
- Verify flows
- Check topology
- Ping hosts
- Link up
- Verify flows
- Check topology
- Ping hosts
- Remove intents
Required:
name - Type of host intent to add eg. IPV4 | VLAN | Dualstack
host1 - Name of first host
host2 - Name of second host
Optional:
onosNode - ONOS node to install the intents in main.CLIs[ ]
0 by default so that it will always use the first
ONOS node
host1Id - ONOS id of the first host eg. 00:00:00:00:00:01/-1
host2Id - ONOS id of the second host
mac1 - Mac address of first host
mac2 - Mac address of the second host
vlan1 - Vlan tag of first host, defaults to -1
vlan2 - Vlan tag of second host, defaults to -1
sw1 - First switch to bring down & up for rerouting purpose
sw2 - Second switch to bring down & up for rerouting purpose
expectedLink - Expected link when the switches are down, it should
be two links lower than the links before the two
switches are down
Return:
Returns main.TRUE if all verification passed, otherwise return

Verify Single to Multi Point intents
NOTE:If main.hostsData is not defined, variables data should be passed in the
same order index wise. All devices in the list should have the same
format, either all the devices have its port or it doesn't.
eg. hostName = [ 'h1', 'h2' ,.. ]
devices = [ 'of:0000000000000001', 'of:0000000000000002', ...]
ports = [ '1', '1', ..]
...
Description:
Verify add-multi-to-single-intent
Steps:
- Get device ids | ports
- Add multi to single point intents
- Check intents
- Verify flows
- Ping hosts
- Reroute
- Link down
- Verify flows
- Check topology
- Ping hosts
- Link up
- Verify flows
- Check topology
- Ping hosts
- Remove intents
Required:
name - Type of point intent to add eg. IPV4 | VLAN | Dualstack
hostNames - List of host names
Optional:
onosNode - ONOS node to install the intents in main.CLIs[ ]
0 by default so that it will always use the first
ONOS node
devices - List of device ids in the same order as the hosts
in hostNames
ports - List of port numbers in the same order as the device in
devices
ethType - Ethernet type eg. IPV4, IPV6
macs - List of hosts mac address in the same order as the hosts in
hostNames
bandwidth - Bandwidth capacity
lambdaAlloc - Allocate lambda, defaults to False
ipProto - IP protocol
ipAddresses - IP addresses of host in the same order as the hosts in
hostNames
tcp - TCP ports in the same order as the hosts in hostNames
sw1 - First switch to bring down & up for rerouting purpose
sw2 - Second switch to bring down & up for rerouting purpose
expectedLink - Expected link when the switches are down, it should
be two links lower than the links before the two
switches are down
