Brady,
Take a look at MatchVlanBuilder.java in genius. We set a Boolean field to
indicate whether vlan id is present or not.
protected void populateBuilder(VlanMatchBuilder builder) {
builder.setVlanId(new VlanIdBuilder()
.setVlanId(new VlanId(vlanId))
.setVlanIdPresent(vlanId != 0)
.build());
}
Thanks,
Faseela

Subject: Re: [openflowplugin-dev] How to match on VLAN
IIRC this is based off Nitrogen-SR2, so shouldn't be prone to the issues listed
there.
Thanks!

Not sure if this would help ( I was trying something a little different than

I had much better luck with Nitrogen

Hello,
Im trying to write flows to pop-vlan or just simply set the vlan-id, but the
flows arent being written to operational, nor the bridge. I tried doing an
etherType match on VLAN (0x8100) but that doesnt help.
The 2 use cases I have are for flows that ingress the bridge with VLAN already
set are:
1) if VLAN present (could be lots of different vlan IDs), pop it.
2) if VLAN present set the VLAN id to a different one.
Ive tried flows for both of these cases, and neither are written to
Operational. Ideally there should be an 802.1Q TPID (Tag protocol ID) match
field, where you could match on 0x8100, but I couldnt find anything like this.
