c483d489 | 3 | - New FAQ. Please send updates and additions! |
5498c01f BP |
4 | - ovs-ofctl: |
5 | - "mod-port" command can now control all OpenFlow config flags. | |
c08201d6 | 6 | - OpenFlow: |
ff0b06ee BP |
7 | - Allow general bitwise masking for IPv4 and IPv6 addresses in |
8 | IPv4, IPv6, and ARP packets. (Previously, only CIDR masks | |
c08201d6 BP |
9 | were allowed.) |
10 | - Allow support for arbitrary Ethernet masks. (Previously, only | |
11 | the multicast bit in the destination address could be individually | |
12 | masked.) | |
c93f9a78 EJ |
13 | - Additional protocols are not mirrored and dropped when forward-bpdu is |
14 | false. For a full list, see the ovs-vswitchd.conf.db man page. | |
38f7147c EJ |
15 | - Open vSwitch now sends RARP packets in situations where it previously |
16 | sent a custom protocol, making it consistent with behavior of QEMU and | |
17 | VMware. | |

51 | v1.6.0 - 24 Feb 2012 | |
52 | ------------------------ | |
53 | *** Internal only release *** | |
4df08875 | 54 | - bonding |
bdebeece EJ |
55 | - LACP bonds no longer fall back to balance-slb when negotiations fail. |
56 | Instead they drop traffic. | |
4df08875 EJ |
57 | - The default bond_mode changed from SLB to active-backup, to protect |
58 | unsuspecting users from the significant risks of SLB bonds (which are | |
59 | documented in vswitchd/INTERNALS). | |
bc1b010c EJ |
60 | - Load balancing can be disabled by setting the bond-rebalance-interval |
61 | to zero. | |
73f33563 BP |
62 | - OpenFlow: |
63 | - Added support for bitwise matching on TCP and UDP ports. | |
64 | See ovs-ofctl(8) for more information. | |
80d5aefd BP |
65 | - NXM flow dumps now include times elapsed toward idle and hard |
66 | timeouts. | |
67 | - Added an OpenFlow extension NXT_SET_ASYNC_CONFIG that allows | |
68 | controllers more precise control over which OpenFlow messages they | |
69 | receive asynchronously. | |
0e553d9c BP |
70 | - New "fin_timeout" action. |
71 | - Added "fin_timeout" support to "learn" action. | |
a7349929 BP |
72 | - New Nicira action NXAST_CONTROLLER that offers additional features |
73 | over output to OFPP_CONTROLLER. | |
2c999774 BP |
74 | - When QoS settings for an interface do not configure a default queue |
75 | (queue 0), Open vSwitch now uses a default configuration for that | |
76 | queue, instead of dropping all packets as in previous versions. | |
2a3e30b2 BP |
77 | - Logging: |
78 | - Logging to console and file will have UTC timestamp as a default for | |
79 | all the daemons. An example of the default format is | |
80 | 2012-01-27T16:35:17Z. ovs-appctl can be used to change the default | |
81 | format as before. | |
82 | - The syntax of commands and options to set log levels was simplified, | |
83 | to make it easier to remember. | |
254750ce BP |
84 | - New support for limiting the number of flows in an OpenFlow flow |
85 | table, with configurable policy for evicting flows upon | |
86 | overflow. See the Flow_Table table in ovs-vswitch.conf.db(5) | |
87 | for more information. | |
9886b662 BP |
88 | - New "enable-async-messages" column in the Controller table. If set to |
89 | false, OpenFlow connections to the controller will initially have all | |
90 | asynchronous messages disabled, overriding normal OpenFlow behavior. | |
1745cd08 BP |
91 | - ofproto-provider interface: |
92 | - "struct rule" has a new member "used" that ofproto implementations | |
93 | should maintain by updating with ofproto_rule_update_used(). | |
8f46c9bb BP |
94 | - ovsdb-client: |
95 | - The new option --timestamp causes the "monitor" command to print | |
96 | a timestamp with every update. | |
a7aa2d3c | 97 | - CFM module CCM broadcasts can now be tagged with an 802.1p priority. |
d0a8c2e0 JP |

112 | - ovsdb-tool now uses the typical database and schema installation |
113 | directories as defaults. | |
d1add61d JP |
114 | - The default MAC learning timeout has been increased from 60 seconds |
115 | to 300 seconds. The MAC learning timeout is now configurable. | |
e68bfcfc JP |
116 | |

ef13dc11 | 118 | v1.4.0 - 30 Jan 2012 |
b6a9a95b | 119 | ------------------------ |
50bf17cd | 120 | - Compatible with Open vSwitch kernel module included in Linux 3.3. |
52a90c29 BP |
121 | - New "VLAN splinters" feature to work around buggy device drivers |
122 | in old Linux versions. (This feature is deprecated. When | |
123 | broken device drivers are no longer in widespread use, we will | |
124 | delete this feature.) See ovs-vswitchd.conf.db(5) for more | |
125 | information. | |
fa8223b7 JP |
126 | - OpenFlow: |
127 | - Added ability to match on IPv6 flow label through NXM. | |

9d24de3b | 132 | - ovs-vswitchd: |
c06bba01 JP |
133 | - Don't require the "normal" action to use mirrors. Traffic will |
134 | now be properly mirrored for any flows, regardless of their | |
135 | actions. | |
9d24de3b | 136 | - Track packet and byte statistics sent on mirrors. |
733adf2a LG |
137 | - The sFlow implementation can now usually infer the correct agent |
138 | device instead of having to be told explicitly. | |
f0a3aa2e AA |
139 | - ovs-appctl: |
140 | - New "fdb/flush" command to flush bridge's MAC learning table. | |
0be6140a AA |
141 | - ovs-test: |
142 | - A new distributed testing tool that allows one to diagnose performance | |
143 | and connectivity issues. This tool currently is not included in RH or | |
144 | Xen packages. | |
0fb42626 | 145 | - RHEL packaging now supports integration with Red Hat network scripts. |
4c57c3bc EJ |
146 | - bonding: |
147 | - Post 1.4.*, OVS will be changing the default bond mode from balance-slb | |
148 | to active-backup. SLB bonds carry significant risks with them | |
149 | (documented vswitchd/INTERNALS) which we want to prevent unsuspecting | |
150 | users from running into. Users are advised to update any scripts or | |
151 | configuration which may be negatively impacted by explicitly setting | |
152 | the bond mode which they want to use. | |
b6a9a95b | 153 | |
0be6140a | 154 | |
ddc29387 | 155 | v1.3.0 - 09 Dec 2011 |

29901626 BP |
170 | - ovs-vswitchd: |
171 | - The software switch now supports 255 OpenFlow tables, instead | |
172 | of just one. By default, only table 0 is consulted, but the | |
173 | new NXAST_RESUBMIT_TABLE action can look up in additional | |
174 | tables. Tables 128 and above are reserved for use by the | |
175 | switch itself; please use only tables 0 through 127. | |
21f7563c | 176 | - Add support for 802.1D spanning tree (STP). |
7257b535 BP |
177 | - Fragment handling extensions: |

179 | fields are made available for matching in fragments with | |
180 | offset 0. | |
181 | - New NXM_NX_IP_FRAG match field for matching IP fragments (usable | |
182 | via "ip_frag" in ovs-ofctl). | |
183 | - New ovs-ofctl "get-frags" and "set-frags" commands to get and set | |
184 | fragment handling policy. | |
2f4bc10d BP |
185 | - CAPWAP tunneling now supports an extension to transport a 64-bit key. |
186 | By default it remains compatible with the old version and other | |
c87112ca | 187 | standards-based implementations. |
17411ecf JG |
188 | - Flow setups are now processed in a round-robin manner across ports |
189 | to prevent any single client from monopolizing the CPU and conducting | |
190 | a denial of service attack. | |
ecac4ebf BP |
191 | - Added support for native VLAN tagging. A new "vlan_mode" |
192 | parameter can be set for "port". Possible values: "access", | |
193 | "trunk", "native-tagged" and "native-untagged". | |
023e1e0a | 194 | - test-openflowd has been removed. Please use ovs-vswitchd instead. |

206 | - Support cooperative locking between callers. | |
207 | - ovs-dpctl: | |
208 | - New "-s" option for "show" command prints packet and byte | |
209 | counters for each port. | |

218 | use ovs-vswitchd instead. | |
1a142ced JP |
219 | - New ovs-benchmark utility to test flow setup performance. |
220 | - A new log level "off" has been added. Configuring a log facility | |
221 | "off" prevents any messages from being logged to it. Previously, | |
222 | "emer" was effectively "off" because no messages were ever logged at | |
223 | level "emer". Now, errors that cause a process to exit are logged | |
224 | at "emer" level. | |
8a2d6596 BP |
225 | - "configure" option --with-l26 has been renamed --with-linux, and |
226 | --with-l26-source has been renamed --with-linux-source. The old | |

228 | your scripts. | |
22bcc0e7 JG |
229 | - The "-2.6" suffix has been dropped from the datapath/linux-2.6 and |
230 | datapath/linux-2.6/compat-2.6 directories. | |
b78f6b77 BP |
231 | - Feature removals: |
232 | - Dropped support for "tun_id_from_cookie" OpenFlow extension. | |
0be6140a | 233 | Please use the extensible match extensions instead. |
93b8df38 EJ |
234 | - Removed the Maintenance_Point and Monitor tables in an effort |
235 | to simplify 802.1ag configuration. | |
1a142ced JP |
236 | - Performance and scalability improvements |
237 | - Bug fixes | |
b78f6b77 | 238 | |

264 | - New commands for working with the new Managers table. | |
265 | - "list" command enhanced with new formatting options and --columns | |
266 | option. | |
267 | - "get" command now accepts new --id option. | |
268 | - New "find" command. | |
269 | - ovs-ofctl: | |
270 | - New "queue-stats" command for printing queue stats. | |
271 | - New commands "replace-flows" and "diff-flows". | |
272 | - Commands to add and remove flows can now read from files. | |

283 | - New "multipath" experimental action extension. | |
284 | - New support for matching multicast Ethernet frames, via NXM. | |
285 | - New extension for OpenFlow vendor error codes. | |
286 | - New extension to set the QoS output queue without actually | |
287 | sending to an output port. | |
288 | - Open vSwitch now reports a single flow table, instead of | |
289 | separate hash and wildcard tables. This better models the | |
290 | current implementation. | |
291 | - New experimental "note" action. | |
292 | - New "ofproto/trace" ovs-appctl command and associated utilities | |
293 | to ease debugging complex flow tables. | |
294 | - Database: | |
295 | - Schema documentation now includes an entity-relationship diagram. | |
296 | - The database is now garbage collected. In most tables, | |
