7 | - New "VLAN splinters" feature to work around buggy device drivers |
8 | in old Linux versions. (This feature is deprecated. When | |
9 | broken device drivers are no longer in widespread use, we will | |
10 | delete this feature.) See ovs-vswitchd.conf.db(5) for more | |
11 | information. | |
fa8223b7 JP |
12 | - OpenFlow: |
13 | - Added ability to match on IPv6 flow label through NXM. | |
530180fd | 14 | - Added ability to match on ECN bits in IPv4 and IPv6 through NXM. |
a61680c6 | 15 | - Added ability to match on TTL in IPv4 and IPv6 through NXM. |
530180fd | 16 | - Added ability to modify ECN bits in IPv4. |
a61680c6 | 17 | - Added ability to modify TTL in IPv4. |

c06bba01 JP |
19 | - Don't require the "normal" action to use mirrors. Traffic will |
20 | now be properly mirrored for any flows, regardless of their | |
21 | actions. | |
9d24de3b | 22 | - Track packet and byte statistics sent on mirrors. |
733adf2a LG |
23 | - The sFlow implementation can now usually infer the correct agent |
24 | device instead of having to be told explicitly. | |
f0a3aa2e AA |
25 | - ovs-appctl: |
26 | - New "fdb/flush" command to flush bridge's MAC learning table. | |
0be6140a AA |
27 | - ovs-test: |
28 | - A new distributed testing tool that allows one to diagnose performance | |
29 | and connectivity issues. This tool currently is not included in RH or | |
30 | Xen packages. | |
0fb42626 | 31 | - RHEL packaging now supports integration with Red Hat network scripts. |
4c57c3bc EJ |
32 | - bonding: |
33 | - Post 1.4.*, OVS will be changing the default bond mode from balance-slb | |
34 | to active-backup. SLB bonds carry significant risks with them | |
35 | (documented vswitchd/INTERNALS) which we want to prevent unsuspecting | |
36 | users from running into. Users are advised to update any scripts or | |
37 | configuration which may be negatively impacted by explicitly setting | |
38 | the bond mode which they want to use. | |

43 | - OpenFlow: |
44 | - Added an OpenFlow extension which allows the "output" action to accept | |
45 | NXM fields. | |
75a75043 | 46 | - Added an OpenFlow extension for flexible learning. |
d2c0fed9 | 47 | - Bumped number of NXM registers from four to five. |
d5e1e5ed | 48 | - ovs-appctl: |
ae75dae3 JP |
49 | - New "version" command to determine version of running daemon. |
50 | - If no argument is provided for "cfm/show", displays detailed | |
51 | information about all interfaces with CFM enabled. | |
5dab8ece JP |
52 | - If no argument is provided for "lacp/show", displays detailed |
53 | information about all ports with LACP enabled. | |
10500639 BP |
54 | - ovs-dpctl: |
55 | - New "set-if" command to modify a datapath port's configuration. | |
29901626 BP |
56 | - ovs-vswitchd: |
57 | - The software switch now supports 255 OpenFlow tables, instead | |
58 | of just one. By default, only table 0 is consulted, but the | |
59 | new NXAST_RESUBMIT_TABLE action can look up in additional | |
60 | tables. Tables 128 and above are reserved for use by the | |
61 | switch itself; please use only tables 0 through 127. | |
21f7563c | 62 | - Add support for 802.1D spanning tree (STP). |
7257b535 BP |
63 | - Fragment handling extensions: |
64 | - New OFPC_FRAG_NX_MATCH fragment handling mode, in which L4 | |
65 | fields are made available for matching in fragments with | |
66 | offset 0. | |
67 | - New NXM_NX_IP_FRAG match field for matching IP fragments (usable | |
68 | via "ip_frag" in ovs-ofctl). | |
69 | - New ovs-ofctl "get-frags" and "set-frags" commands to get and set | |
70 | fragment handling policy. | |
c87112ca JG |
71 | - CAPWAP tunneling now supports an extension to transport a 64-key. By |
72 | default it remains compatible with the old version and other | |
73 | standards-based implementations. | |
17411ecf JG |
74 | - Flow setups are now processed in a round-robin manner across ports |
75 | to prevent any single client from monopolizing the CPU and conducting | |
76 | a denial of service attack. | |
ecac4ebf BP |
77 | - Added support for native VLAN tagging. A new "vlan_mode" |
78 | parameter can be set for "port". Possible values: "access", | |
79 | "trunk", "native-tagged" and "native-untagged". | |
023e1e0a | 80 | - test-openflowd has been removed. Please use ovs-vswitchd instead. |

1a142ced JP |
84 | - New "ofproto" abstraction layer to ease porting to hardware |
85 | switching ASICs. | |
86 | - Packaging for Red Hat Enterprise Linux 5.6 and 6.0. | |
87 | - Datapath support for Linux kernels up to 3.0. | |
88 | - OpenFlow: | |
89 | - New "bundle" and "bundle_load" action extensions. | |
90 | - Database: | |
91 | - Implement table unique constraints. | |
92 | - Support cooperative locking between callers. | |
93 | - ovs-dpctl: | |
94 | - New "-s" option for "show" command prints packet and byte | |
95 | counters for each port. | |
c4ea79bf BP |
96 | - ovs-ofctl: |
97 | - New "--readd" option for "replace-flows". | |
9b1735a7 BP |
98 | - ovs-vsctl: |
99 | - New "show" command to print an overview of configuration. | |
1a142ced | 100 | - New "comment" command to add remark that explains intentions. |
2b01925c | 101 | - ovs-brcompatd has been rewritten to fix long-standing bugs. |
045b2e5c BP |
102 | - ovs-openflowd has been renamed test-openflowd and moved into the |
103 | tests directory. Its presence confused too many users. Please | |
104 | use ovs-vswitchd instead. | |
1a142ced JP |
105 | - New ovs-benchmark utility to test flow setup performance. |
106 | - A new log level "off" has been added. Configuring a log facility | |
107 | "off" prevents any messages from being logged to it. Previously, | |
108 | "emer" was effectively "off" because no messages were ever logged at | |
109 | level "emer". Now, errors that cause a process to exit are logged | |
110 | at "emer" level. | |
8a2d6596 BP |
111 | - "configure" option --with-l26 has been renamed --with-linux, and |
112 | --with-l26-source has been renamed --with-linux-source. The old | |
113 | names will be removed after the next release, so please update | |
114 | your scripts. | |
22bcc0e7 JG |
115 | - The "-2.6" suffix has been dropped from the datapath/linux-2.6 and |
116 | datapath/linux-2.6/compat-2.6 directories. | |
b78f6b77 BP |
117 | - Feature removals: |
118 | - Dropped support for "tun_id_from_cookie" OpenFlow extension. | |
0be6140a | 119 | Please use the extensible match extensions instead. |
93b8df38 EJ |
120 | - Removed the Maintenance_Point and Monitor tables in an effort |
121 | to simplify 802.1ag configuration. | |
1a142ced JP |
122 | - Performance and scalability improvements |
123 | - Bug fixes | |

150 | - New commands for working with the new Managers table. | |
151 | - "list" command enhanced with new formatting options and --columns | |
152 | option. | |
153 | - "get" command now accepts new --id option. | |
154 | - New "find" command. | |
155 | - ovs-ofctl: | |
156 | - New "queue-stats" command for printing queue stats. | |

168 | - New "register" extension for use in matching and actions, via NXM. |
169 | - New "multipath" experimental action extension. | |
170 | - New support for matching multicast Ethernet frames, via NXM. | |
171 | - New extension for OpenFlow vendor error codes. | |
172 | - New extension to set the QoS output queue without actually | |
173 | sending to an output port. | |
174 | - Open vSwitch now reports a single flow table, instead of | |
175 | separate hash and wildcard tables. This better models the | |
176 | current implementation. | |
177 | - New experimental "note" action. | |
178 | - New "ofproto/trace" ovs-appctl command and associated utilities | |
179 | to ease debugging complex flow tables. | |
180 | - Database: | |

195 | - Many "name" columns are now immutable. | |
196 | - Feature removals: | |
197 | - Dropped support for XenServer pre-5.6.100. | |
198 | - Dropped support for Linux pre-2.6.18. | |
