#### Test case #1 - Verrify send a wol packet to a specific interface
1. Start `tcpdump` process in PTF to capture WoL packet on spacific interface. Save the captured packets to `.pcap` file.
1. Issue command on DUT host: `wol <sonic_interface_name> <target_mac>` (e.g., `wol Ethernet10 00:11:22:33:44:55`)
1. Issue command on DUT host:
1. Send magic pattern in ethernet payload: `wol <sonic_interface_name> <target_mac>` (e.g., `wol Ethernet10 00:11:22:33:44:55`)
1. Send magic pattern in udp payload with ipv4 address: `wol <sonic_interface_name> <target_mac> <udp> <ip-address>` (e.g., `wol Ethernet10 00:11:22:33:44:55 -u --ip-address 255.255.255.255`)

1. Start multiple `tcpdump` processes in PTF to capture WoL packet on each interfaces. Save the captured packets to different `.pcap` files.

#### Test case #7 - Verify constrain of parameters
1. Make sure count and interval both exist or not.
1. Make sure udp flag is required when using ip address or udp port.
1. Make sure udp flag is conflict with mac broadcast flag.

#### Test case #8 - Verify parameters can be set correctly by CLI
1. Make sure interface that receving packet and command line parameter interface are same.
1. Make sure target_mac in payload and command line parameter target_mac are same.
1. Make sure ip address in header and command line parameter ip_address are same. (Test both ipv4 and ipv6 address with broadcase address or unicast address on VLAN interface or port interface, so there should be 8 combinations, maybe we can leverage pytest parametrize mark to realize that.)
1. Make sure when command line parameter ip_address is empty, ip address in header is default value: 255.255.255.255.
1. Make sure udp port in header and command line parameter udp port are same.
1. Make sure when command line parameter udp_port is empty, udp port in header is default value: 9.

[^1]: ALMOST SAME means we should tolerate small errors caused by electrical characteristics.
