Hi，
I use pox as my controller. We set up a testbed using openflow switch that
support openflow 1.3.
But when I use pox to add flow-table to the openflow switch, I find that the
flow-table is not right.
Here is the "ofp_flow_mod" structure in pox:
ofp_flow_mod
header:
version: 1
type: 14 (OFPT_FLOW_MOD)
length: 80
xid: 25
match:
wildcards:
nw_tos|tp_dst|dl_dst|dl_src|dl_vlan_pcp|nw_proto|dl_vlan|tp_src|dl_type|nw_src(/0)
(1100000010000011111110 = 3020fe)
in_port: 1
nw_dst: 10.4.4.2
cookie: 0
command: 0
idle_timeout: 3600
hard_timeout: 3600
priority: 1024
buffer_id: None
out_port: 65535
flags: 0
actions:
type: 0
len: 8
port: 5
max_len: 65535
But I see the following flow table in my openflow switch:
Dell-S4820T>show openflow flows of-instance 1
Instance: 1, Table: acl, Flow: 1, Cookie: 0x0
Priority: 1024, Internal Priority: 1024
Up Time: 0d 00:01:29, Hard Timeout: 3600 seconds
Idle Timeout: 3600 seconds, Internal Idle Timeout: 3600 seconds
Packets: 0, Bytes: 0
Match Parameters:
Valid Match: InPort
In Port : Te 0/0 EType : *
SMAC : * DMAC : *
VLAN id : * VLAN PCP : *
IP TOS : * IP proto : *
Src IP : * Dest IP : *
Src Port : * Dest Port : *
Actions:
Output: Te 0/4
(port starts at 0, so the port in switch = the port in flow-mod -1)
We see that the flow table only match inport. But the flow-mod shows it should
match inport and nw_dst.
I don't know what happend?
Thank you!
