[ovs-discuss] 答复: Why the NSH is not been supported by the ovs-2.9.0?

[hai tsing]

I debug out the root！

OVS 2.9.0 doesn’t recognize the the following action format which used by neutron network-sfc agent.
（actions=encap(hdr=nsh,prop(class=nsh,type=md_type,val=1)),set_field:0x1->nsh_spi,set_field:0xff->nsh_si,encap(hdr=ethernet)）

The right one :
（actions=encap(nsh,prop(class=nsh,type=md_type,val=1)),set_field:0x1->nsh_spi,set_field:0xff->nsh_si,encap(hdr=ethernet)）

Are you using OVS kernel datapath?  You can double check it by adding flows manually.

Dear all:


I encounter a trouble that my ovs does't support nsh!

When the openstack networking-sfc was populating some flows,  the following ERROR occures.
when I was looking for resolution,  The ovs release note tells that nsh is supported on version 2.9.0(http://www.openvswitch.org//releases/NEWS-2.10.0.txt<http://www.openvswitch.org/releases/NEWS-2.10.0.txt>).

so what should i do for enabling NSH of ovs?
