[ovs-discuss] LISP tunneling - port type=lisp, how to get the port number to configure the flows?

[Diego Montero]

Hi Lori,

Thanks for your answer. The problem, as you mentioned, was the kernel module. 
I installed the kernel module from OVS and now I am able to see the port 
number (type=lisp).

$ovs-ofctl show br0
OFPT_FEATURES_REPLY (xid=0x2): dpid:0000d8d385637d15
n_tables:254, n_buffers:256
capabilities: FLOW_STATS TABLE_STATS PORT_STATS QUEUE_STATS ARP_MATCH_IP
actions: OUTPUT SET_VLAN_VID SET_VLAN_PCP STRIP_VLAN SET_DL_SRC SET_DL_DST 
SET_NW_SRC SET_NW_DST SET_NW_TOS SET_TP_SRC SET_TP_DST ENQUEUE
 1(vnet0): addr:fe:54:00:1c:6e:b2
     config:     0
     state:      0
     current:    10MB-FD COPPER
     speed: 10 Mbps now, 0 Mbps max
 3(lisp0): addr:ba:57:0d:1d:c4:a4
     config:     0
     state:      0
     speed: 0 Mbps now, 0 Mbps max
 LOCAL(br0): addr:d8:d3:85:63:7d:15
     config:     PORT_DOWN
     state:      LINK_DOWN
     speed: 0 Mbps now, 0 Mbps max
OFPT_GET_CONFIG_REPLY (xid=0x4): frags=normal miss_send_len=0

Regards,
Diego Montero.
