d8b11fb9 | 13 | v1.7.0 - xx xxx xxxx |
dd1ba5b3 | 14 | ------------------------ |
9b80f761 CW |
15 | - kernel modules are renamed. openvswitch_mod.ko is now |
16 | openvswitch.ko and brcompat_mod.ko is now brcompat.ko. | |
e9358af6 | 17 | - Increased the number of NXM registers to 8. |
f125905c MM |
18 | - Added ability to configure dscp setting for manager and controller |
19 | connections. By default, these connections have a DSCP value of | |
20 | Internetwork Control (0xc0). | |
3967a833 MM |
21 | - Added the granular link health statistics, 'cfm_health', to an |
22 | interface. | |
47284b1f AA |

d0a8c2e0 | 40 | ------------------------ |
4df08875 | 41 | - bonding |
bdebeece EJ |
42 | - LACP bonds no longer fall back to balance-slb when negotiations fail. |
43 | Instead they drop traffic. | |
4df08875 EJ |
44 | - The default bond_mode changed from SLB to active-backup, to protect |
45 | unsuspecting users from the significant risks of SLB bonds (which are | |
46 | documented in vswitchd/INTERNALS). | |
bc1b010c EJ |
47 | - Load balancing can be disabled by setting the bond-rebalance-interval |
48 | to zero. | |
73f33563 BP |
49 | - OpenFlow: |
50 | - Added support for bitwise matching on TCP and UDP ports. | |
51 | See ovs-ofctl(8) for more information. | |
80d5aefd BP |
52 | - NXM flow dumps now include times elapsed toward idle and hard |
53 | timeouts. | |
54 | - Added an OpenFlow extension NXT_SET_ASYNC_CONFIG that allows | |
55 | controllers more precise control over which OpenFlow messages they | |
56 | receive asynchronously. | |
0e553d9c BP |
57 | - New "fin_timeout" action. |
58 | - Added "fin_timeout" support to "learn" action. | |
a7349929 BP |
59 | - New Nicira action NXAST_CONTROLLER that offers additional features |
60 | over output to OFPP_CONTROLLER. | |
2c999774 BP |
61 | - When QoS settings for an interface do not configure a default queue |
62 | (queue 0), Open vSwitch now uses a default configuration for that | |
63 | queue, instead of dropping all packets as in previous versions. | |
2a3e30b2 BP |
64 | - Logging: |
65 | - Logging to console and file will have UTC timestamp as a default for | |
66 | all the daemons. An example of the default format is | |
67 | 2012-01-27T16:35:17Z. ovs-appctl can be used to change the default | |
68 | format as before. | |
69 | - The syntax of commands and options to set log levels was simplified, | |
70 | to make it easier to remember. | |
254750ce BP |
71 | - New support for limiting the number of flows in an OpenFlow flow |
72 | table, with configurable policy for evicting flows upon | |
73 | overflow. See the Flow_Table table in ovs-vswitch.conf.db(5) | |
74 | for more information. | |
9886b662 BP |
75 | - New "enable-async-messages" column in the Controller table. If set to |
76 | false, OpenFlow connections to the controller will initially have all | |
77 | asynchronous messages disabled, overriding normal OpenFlow behavior. | |
1745cd08 BP |
78 | - ofproto-provider interface: |
79 | - "struct rule" has a new member "used" that ofproto implementations | |
80 | should maintain by updating with ofproto_rule_update_used(). | |
8f46c9bb BP |
81 | - ovsdb-client: |
82 | - The new option --timestamp causes the "monitor" command to print | |
83 | a timestamp with every update. | |
a7aa2d3c | 84 | - CFM module CCM broadcasts can now be tagged with an 802.1p priority. |

98 | {=}, {!=}, {<}, {>}, {<=}, and {>=}. | |
e4476f74 BP |
99 | - ovsdb-tool now uses the typical database and schema installation |
100 | directories as defaults. | |
d1add61d JP |
101 | - The default MAC learning timeout has been increased from 60 seconds |
102 | to 300 seconds. The MAC learning timeout is now configurable. | |

ef13dc11 | 105 | v1.4.0 - 30 Jan 2012 |
b6a9a95b | 106 | ------------------------ |
50bf17cd | 107 | - Compatible with Open vSwitch kernel module included in Linux 3.3. |
52a90c29 BP |
108 | - New "VLAN splinters" feature to work around buggy device drivers |
109 | in old Linux versions. (This feature is deprecated. When | |
110 | broken device drivers are no longer in widespread use, we will | |
111 | delete this feature.) See ovs-vswitchd.conf.db(5) for more | |
112 | information. | |
fa8223b7 JP |
113 | - OpenFlow: |
114 | - Added ability to match on IPv6 flow label through NXM. | |

530180fd | 117 | - Added ability to modify ECN bits in IPv4. |
a61680c6 | 118 | - Added ability to modify TTL in IPv4. |
9d24de3b | 119 | - ovs-vswitchd: |
c06bba01 JP |
120 | - Don't require the "normal" action to use mirrors. Traffic will |
121 | now be properly mirrored for any flows, regardless of their | |
122 | actions. | |
9d24de3b | 123 | - Track packet and byte statistics sent on mirrors. |
733adf2a LG |
124 | - The sFlow implementation can now usually infer the correct agent |
125 | device instead of having to be told explicitly. | |
f0a3aa2e AA |
126 | - ovs-appctl: |
127 | - New "fdb/flush" command to flush bridge's MAC learning table. | |
0be6140a AA |
128 | - ovs-test: |
129 | - A new distributed testing tool that allows one to diagnose performance | |
130 | and connectivity issues. This tool currently is not included in RH or | |
131 | Xen packages. | |
0fb42626 | 132 | - RHEL packaging now supports integration with Red Hat network scripts. |
4c57c3bc EJ |
133 | - bonding: |
134 | - Post 1.4.*, OVS will be changing the default bond mode from balance-slb | |
135 | to active-backup. SLB bonds carry significant risks with them | |
136 | (documented vswitchd/INTERNALS) which we want to prevent unsuspecting | |
137 | users from running into. Users are advised to update any scripts or | |
138 | configuration which may be negatively impacted by explicitly setting | |
139 | the bond mode which they want to use. | |

29901626 BP |
157 | - ovs-vswitchd: |
158 | - The software switch now supports 255 OpenFlow tables, instead | |
159 | of just one. By default, only table 0 is consulted, but the | |
160 | new NXAST_RESUBMIT_TABLE action can look up in additional | |
161 | tables. Tables 128 and above are reserved for use by the | |
162 | switch itself; please use only tables 0 through 127. | |
21f7563c | 163 | - Add support for 802.1D spanning tree (STP). |
7257b535 BP |
164 | - Fragment handling extensions: |

166 | fields are made available for matching in fragments with | |
167 | offset 0. | |
168 | - New NXM_NX_IP_FRAG match field for matching IP fragments (usable | |
169 | via "ip_frag" in ovs-ofctl). | |
170 | - New ovs-ofctl "get-frags" and "set-frags" commands to get and set | |
171 | fragment handling policy. | |
2f4bc10d BP |
172 | - CAPWAP tunneling now supports an extension to transport a 64-bit key. |
173 | By default it remains compatible with the old version and other | |
c87112ca | 174 | standards-based implementations. |
17411ecf JG |
175 | - Flow setups are now processed in a round-robin manner across ports |
176 | to prevent any single client from monopolizing the CPU and conducting | |
177 | a denial of service attack. | |
ecac4ebf BP |
178 | - Added support for native VLAN tagging. A new "vlan_mode" |
179 | parameter can be set for "port". Possible values: "access", | |
180 | "trunk", "native-tagged" and "native-untagged". | |
023e1e0a | 181 | - test-openflowd has been removed. Please use ovs-vswitchd instead. |
3e60856b | 182 | |
5e9c5b61 | 183 | v1.2.0 - 03 Aug 2011 |
b78f6b77 | 184 | ------------------------ |

185 | - New "ofproto" abstraction layer to ease porting to hardware |
186 | switching ASICs. | |
187 | - Packaging for Red Hat Enterprise Linux 5.6 and 6.0. | |

191 | - Database: | |
192 | - Implement table unique constraints. | |
193 | - Support cooperative locking between callers. | |
194 | - ovs-dpctl: | |
195 | - New "-s" option for "show" command prints packet and byte | |
196 | counters for each port. | |

205 | use ovs-vswitchd instead. | |
1a142ced JP |
206 | - New ovs-benchmark utility to test flow setup performance. |
207 | - A new log level "off" has been added. Configuring a log facility | |
208 | "off" prevents any messages from being logged to it. Previously, | |
209 | "emer" was effectively "off" because no messages were ever logged at | |
210 | level "emer". Now, errors that cause a process to exit are logged | |
211 | at "emer" level. | |
8a2d6596 BP |
212 | - "configure" option --with-l26 has been renamed --with-linux, and |
213 | --with-l26-source has been renamed --with-linux-source. The old | |
214 | names will be removed after the next release, so please update | |
215 | your scripts. | |
22bcc0e7 JG |
216 | - The "-2.6" suffix has been dropped from the datapath/linux-2.6 and |
217 | datapath/linux-2.6/compat-2.6 directories. | |
b78f6b77 BP |
218 | - Feature removals: |
219 | - Dropped support for "tun_id_from_cookie" OpenFlow extension. | |
0be6140a | 220 | Please use the extensible match extensions instead. |
93b8df38 EJ |
221 | - Removed the Maintenance_Point and Monitor tables in an effort |
222 | to simplify 802.1ag configuration. | |
1a142ced JP |
223 | - Performance and scalability improvements |
224 | - Bug fixes | |
b78f6b77 | 225 | |

255 | - New "find" command. | |
256 | - ovs-ofctl: | |
257 | - New "queue-stats" command for printing queue stats. | |

270 | - New "multipath" experimental action extension. | |
271 | - New support for matching multicast Ethernet frames, via NXM. | |
272 | - New extension for OpenFlow vendor error codes. | |
273 | - New extension to set the QoS output queue without actually | |
274 | sending to an output port. | |
275 | - Open vSwitch now reports a single flow table, instead of | |
276 | separate hash and wildcard tables. This better models the | |
277 | current implementation. | |
278 | - New experimental "note" action. | |
279 | - New "ofproto/trace" ovs-appctl command and associated utilities | |
280 | to ease debugging complex flow tables. | |
281 | - Database: | |
282 | - Schema documentation now includes an entity-relationship diagram. | |
283 | - The database is now garbage collected. In most tables, | |
