Hello,
I'm trying to add a flow on my OVS with tcp port range (e.g. 1000-1007) via
OpenDaylight Lithium controller. I have successfuly installed this flow
directly through CLI on my OVS (command: sudo ovs-ofctl add-flow bridge1 dl
*type=0x800,nw*proto=6,tp_dst=1000/65528,actions=output:1) so I know my OVS
version supports this.
What I want to do now is send REST command to my controller, and then the
controller sends appropriate OpenFlow command to OVS which will add
specified flow. To do this, I need appropirate XML body to send in my REST
command. I've tried with the .xml body presented below, but I'm getting an
error.
<?xml version="1.0" encoding="UTF-8" standalone="no"?> <flow
xmlns="urn:opendaylight:flow:inventory">
<instructions>
<instruction>
<order>0</order>
<apply-actions>
<action>
<order>0</order>
<output-action>
<output-node-connector>1</output-node-connector>
<max-length>60</max-length>
</output-action>
</action>
</apply-actions>
</instruction>
</instructions>
<table_id>0</table_id>
<id>252</id>
<match>
<ethernet-match>
<ethernet-type>
<type>2048</type>
</ethernet-type>
</ethernet-match>
<ip-match>
<ip-protocol>6</ip-protocol>
</ip-match>
<tcp-source-port>1000/65528</tcp-source-port>
</match>
<hard-timeout>0</hard-timeout>
<cookie>10</cookie>
<idle-timeout>0</idle-timeout>
<flow-name>flow-instruction-go-to-tablee</flow-name>
<priority>400</priority> </flow>
I think that I'm not using correct .xml tag for tcp port since I get an
error below.
<errors
xmlns="urn:ietf:params:xml:ns:yang:ietf-restconf">
<error>
<error-type>protocol</error-type>
<error-tag>malformed-message</error-tag>
<error-message>Error parsing input: Incorrect lexical
representation of integer value: 1000/65528.
An integer value can be defined as:
- a decimal number,
- a hexadecimal number (prefix 0x),
- an octal number (prefix 0).
Signed values are allowed. Spaces between digits are NOT
allowed.</error-message>
</error></errors>
It seems that the YANG model does not support tcp port masking according to
this link
https://github.com/opendaylight/openflowplugin/blob/master/model/model-flow-base/src/main/yang/opendaylight-match-types.yang#L203-L212
Could you please clarify if this is really the case and if not, provide
correct syntax for adding tcp port with a mask?
