Special thanks to Ken Chiang for his work on this release.

Update for 2011.11.08

This is a full release including a push to git hub, https://github.com/bigswitch/iods, and new binary images placed on the Indigo site: http://www.openflowhub.org/display/Indigo.

Updates for this release include:

• Fixed a NULL pointer dereference in flow modify; Indigo-115
• Fixed SSH reference in initialization

Update for 2011.10.03

This is a full release including a push to git hub, https://github.com/bigswitch/iods, and new binary images placed on the Indigo site: http://www.openflowhub.org/display/Indigo.

Updates for this release include:

• Support for a max-rate queuing property

Support has been added to allow the specification of the maximum rate for a queue. Like min-rate, this is specified in tenths of a percent (1-1000). This feature may be controlled using dpctl; the appropriate queue commands now take an additional optional parameter.

Update for 2011.09.08

This is a full release including a push to git hub, https://github.com/bigswitch/iods, and new binary images placed on the Indigo site: http://www.openflowhub.org/display/Indigo.

Updates for this release include:

• Support for destination and source MAC address rewrite on the Pronto 3290
• Timestamps on some debug messages
• Re-instatement of the fan daemon, fand, on the 3290
• Support of the Triumph 2 Broadcom Reference Design
• Report the output port in flowtable display in the CLI

This release passes the OFTest suite on the Pronto 3290 and the GSM7328OS platforms. but has received limited validation on other platforms.

Update for 2011.08.15

A source code update was pushed to git hub to address Indigo-98. This affected primarily the binary images.

Supported Platforms

This release targets all current Indigo platforms. However it has received more validation on some platforms. Apologies in advance if your platforms have not received validation. Please report issues to the Indigo forums at http://www.openflowhub.org/display/Indigo.

Original Notes for 2011.08.06

These are the release notes for the 2011.08.06 release of the Indigo software package. This is a comprehensive release that includes source and binary components. The release includes the usual binary flash images to be loaded on to Indigo target platforms.

With this release comes the introduction of IODS, the Indigo Open Development System. This is a source based release with prebuilt binaries for the portions of the code that are covered by NDAs. With this release, the binaries include all of the functionality of the OpenFlow datapath. This may be further refined in the future.

The download pages are pointed to from the Indigo OpenFlow Hub page: http://www.openflowhub.org/display/Indigo

See the release notes for previous releases for features that were add there.

Other Documents

The following documents are included in the release. They should additionally be available on the Indigo support pages on http://www.openflowhub.org/display/Indigo.

Major Updates

There are only two major externally visible updates for this release.

• The CLI has been significantly simplified and made more consistent.
• The IODS build environment is being released.

There has been a significant amount of documentation added for this release.

Licenses

License information for the OpenFlow binaries and for Dropbear are available at: http://www.openflowhub.org/display/Indigo/License+Information.

The Linux kernel code for recent releases is based on versions 2.6.25 - 2.6.27 and is released under GPLv2.

Busybox is version 1.13.3 or 1.14.2 and is released under the GPLv2. It is available at http://busybox.net/downloads/.

Limitations

The following are known limitations for the current platforms. Note that these are generally not expected to be fixed for these platforms.

Counters are byte or packet, not both

For flows, only packet counters or byte counters are supported, not both simultaneously. In the configuration of this release, only packet counters are supported. Applies to all platforms.

Actions sequencing is not supported.

For example, the action list with 4 actions: "(1) set VID to X, (2) output to port A, (3) set VID to Y, (4) output to port B" has the intention of sending the packet out on different ports with different VLANs. This is not supported. However, sending to multiple ports by specifying each port in a different output action is supported. Applies to all platforms.

Not all OpenFlow actions are supported.

The following are not currently supported on any Indigo platform:

        OFPAT_SET_NW_SRC (Set L3 IP source address)
        OFPAT_SET_NW_DST (Set L3 IP destination address)
        OFPAT_SET_TP_SRC (Set L4 source port)
        OFPAT_SET_TP_DST (Set L4 destination port)

The following are only supported on the Pronto 3290 and the Triumph 2 reference:

        OFPAT_SET_DL_SRC (Set L2 MAC source address)
        OFPAT_SET_DL_DST (Set L2 MAC destination address)

OFPAT_STRIP_VLAN (Strip VLAN tag) is supported (but with only limited validation) on the 3290 and 3240 platforms. On other platforms, the function can be implemented by setting to the system's untagged VLAN (untested).

Cannot multicast and wildcard source port.

Actions with a wildcard source port may not specify "flood" nor multicast (multiple output ports) with the expectation of source port blocking.

Known Issues
