BTW,
On top of the previous email, as an example, here is the flow table with vlan
pop action I dumped using openflow rest api. it is in config, but not installed.
{
"flow-node-inventory:table": [
{
"id": 80,
"flow": [
{
"id": "DEFAULT_PIPELINE_FLOW_80",
"hard-timeout": 0,
"idle-timeout": 0,
"match": {},
"instructions": {
"instruction": [
{
"order": 0,
"apply-actions": {
"action": [
{
"order": 0,
"pop-vlan-action": {}
}
]
}
},
{
"order": 1,
"go-to-table": {
"table_id": 110
}
}
]
},
"barrier": true,
"priority": 0,
"table_id": 80,
"flow-name": "DEFAULT_PIPELINE_FLOW_80"
}
]
}
]
}
thanks

Subject: A question regarding VLAN tagging and untagging
Hi,
I have a couple of questions regarding the VLAN relevant action.
1) I have a table in the pipeline which does some L3 forwarding. it has some
entries to match dst ip, then modify dst dl address, dec-ttl, resubmit. etc...
Those flows get installed without problem.
.
Now I try to add a "VLAN strip or pop" into the action list of the flow above
for example as the first action , strip or pop VLAN, then modify dst dl
address, dec-ttl, resubmit, etc... I tried both strip or pop action, but
either way the flow didn't get installed. why is that?
I even tried to just create a separate table with VLAN strip and resubmit as
the default entry, it doesn't get installed either.
2) also I found more strange thing is that If I need to push and set a VLAN ID
in the action, I have to have a VLAN match first, otherwise
the flow is not get installed.
BTW I am doing this NOT using REST API of openflowplugin. but programmatically
using Action, Action builder etc...
Any pointer is greatly appreciated.
Thanks & Regards
Xingjun
