Subject Re: CLOUDSTACK-5502 [Automation] createVlanIpRange API failing, if you pass VLAN
Date Thu, 09 Jan 2014 18:04:21 GMT
Currently if I create my public range with 'untagged', I get:

    "Vlan id is required when add ip range to the public network"

So at the very least it seems the patch is not working. It may be
better to edit CreateVlanIpRangeCmd and change the parameter at the
source if 'untagged' is passed in, like:
     public String getVlan() {
+        if (vlan.equalsIgnoreCase("untagged")) {
+            vlan = "";
+        }
         return vlan;
     }


If I create my public range with "", I get a failure in bringing up
the first system vm:

    Networks.java line 323, "Unable to convert to isolation URI:"

I'm running tests against the version with your patch reverted, but I
think the root is that untagged (and perhaps empty string) was
previously interpreted as Vlan.UNTAGGED in 4.2, and is not in 4.3,
nothing to do with your change.


There is a lot of code that is looking for untagged, or looking for
null, and either setting null to 'untagged' or skipping code entirely
if it is null, e.g. NetworkOrchestrator:

basic networking seems to get around it:

            if (vlanId == null) {
                vlanId = Vlan.UNTAGGED;
            } else {
                if (!vlanId.equalsIgnoreCase(Vlan.UNTAGGED)) {
                    throw new InvalidParameterValueException("Only
vlan " + Vlan.UNTAGGED + " can be created in " + "the zone of type " +
NetworkType.Basic);
                }
            }

but advanced networking skips stuff altogether if vlanId is null
(basic networking set it to UNTAGGED and saved the day per previous
code):

                if (vlanIdFinal != null) {
                        if (isolatedPvlan == null) {
                        URI uri = BroadcastDomainType.fromString(vlanIdFinal);
                        userNetwork.setBroadcastUri(uri);
                                if
(!vlanIdFinal.equalsIgnoreCase(Vlan.UNTAGGED)) {

userNetwork.setBroadcastDomainType(BroadcastDomainType.Vlan);
                                } else {

userNetwork.setBroadcastDomainType(BroadcastDomainType.Native);
                                }
                        } else {
                                if
(vlanIdFinal.equalsIgnoreCase(Vlan.UNTAGGED)) {
                                        throw new
InvalidParameterValueException("Cannot support pvlan with untagged
primary vlan!");
                                }

userNetwork.setBroadcastUri(NetUtils.generateUriForPvlan(vlanIdFinal,
isolatedPvlan));

userNetwork.setBroadcastDomainType(BroadcastDomainType.Pvlan);
                        }
                }
