Hi,
I am trying to test the default maximum value of flow_limit in a
flow_table.
To achieve this, I executed the following commands:
[root@user]# ovs-ofctl dump-tables br0 | less OFPST_TABLE reply (xid=0x1):
255 tables
0: classifier: wild=0x3fffff, max=1000000, active=9
lookup=350074, matched=231250
1: main1 : wild=0x3fffff, max=1000000, active=0
lookup=0, matched=0
2: table2 : wild=0x3fffff, max=1000000, active=0
lookup=0, matched=0
3: table3 : wild=0x3fffff, max=1000000, active=0
lookup=0, matched=0
4: table4 : wild=0x3fffff, max=1000000, active=0
lookup=0, matched=0
5: table5 : wild=0x3fffff, max=1000000, active=0
lookup=0, matched=0
6: table6 : wild=0x3fffff, max=1000000, active=0
lookup=0, matched=0
:
Using script, I added flow entries to the table 1.
On again executing dump-tables command, the result is as follows:
[root@user]# ovs-ofctl dump-tables br0 | less OFPST_TABLE reply (xid=0x1):
255 tables
0: classifier: wild=0x3fffff, max=1000000, active=9
lookup=350329, matched=231641
1: table1 : wild=0x3fffff, max=1000000, active=100001
lookup=0, matched=0
2: table2 : wild=0x3fffff, max=1000000, active=0
lookup=0, matched=0
3: table3 : wild=0x3fffff, max=1000000, active=0
lookup=0, matched=0
4: table4 : wild=0x3fffff, max=1000000, active=0
lookup=0, matched=0
5: table5 : wild=0x3fffff, max=1000000, active=0
lookup=0, matched=0
6: table6 : wild=0x3fffff, max=1000000, active=0
lookup=0, matched=0
:
In table1, the active flow entries exceed the max value.
But when I change the max flow_limit of a table, then the scenario works
fine.
Following are the commands executed:
[root@user]# ovs-vsctl -- --id=@t1 create Flow_Table flow-limit=2 -- set
bridge br0 flow_tables={1=@t1}
f5f725e6-b30a-499f-b053-bdca5dcbd0d8
[root@user]#
[root@user]# ovs-vsctl list flow_table
_uuid : f5f725e6-b30a-499f-b053-bdca5dcbd0d8
flow_limit : 2
groups : []

overflow_policy : []

lookup=0, matched=0
6: table6 : wild=0x3fffff, max=1000000, active=0
lookup=0, matched=0
:
Please let me know if the above behavior is expected??

Akash
