Hi, Tahereh

I capture the input port of next node in wireshark, vlan_id is correct, but the packet is dropped!

Could you check 'dl_dst' in the packet, too?
The rule you installed seems to have two match fields, 'dl_vlan' and 'dl_dst':

cookie=0x0, duration=1447.496s, table=0, n_packets=0, n_bytes=0, priority=32770,dl_vlan=198,dl_dst=10:00:00:00:00:02 actions=output:2
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
So packets will be dropped unless it satisfies all of these match fields.

Thanks,
Fujimoto

Hi,

I'm trying to implement a Ryu app that calculates main and backup paths and save their rules in flow & group tables. in my code I need to use vlan_id for tagging packets in group table actions like this:

group_id=6,type=ff,bucket=weight:0,watch_port:2,actions=output:2,bucket=weight:0,watch_port:1,actions=output:1,set_field:4358->vlan_vid

when i down port 2 (in mininet) , it adds vlan_id= 198 and sends the packet from port 1, but in the next ​node the packet does not match with this rule:

cookie=0x0, duration=1447.496s, table=0, n_packets=0, n_bytes=0, priority=32770,dl_vlan=198,dl_dst=10:00:00:00:00:02 actions=output:2


I capture the input port of next node in wireshark, vlan_id is correct, but the packet is dropped!


my Ryu code is like this:
buckets.append(parser.OFPBucket(watch_port=_port,actions=[
     parser.OFPActionOutput(_port),
     parser.OFPActionSetField(vlan_vid=ofp.OFPVID_PRESENT | failure_id)
]))
match =parser.OFPMatch(vlan_vid=(failure_id | ofp.OFPVID_PRESENT),eth_dst=dst_)
Thanks in advance
