Hi,
I try to set up config with vman/QinQ. I'd like move vlans 101,102,103..between summits 450a (xos 15.3) via vman1 with tag 804. I made loop between port 1 and 2 for test purpose on the same switch. Till now i can ping only vman1 interfaces.. what am i doing wrong ?

schema:
http://tnij.org/y7pn

my conf:
summit1:

enable jumbo-frame ports all
configure vman ethertype 0x8100

create vlan "vlan101"
configure vlan vlan101 tag 101
create vman "vman1"
configure vman vman1 tag 804

configure vlan vlan101 add ports 2 untagged
configure vman vman1 add ports 24 tagged
configure vman vman1 add ports 1 untagged

configure vlan vman1 ipaddress 192.168.1.11 255.255.255.0
configure vlan vlan101 ipaddress 192.168.0.11 255.255.255.0

enable dot1p examination inner-tag port 24

summit2

enable jumbo-frame ports all
configure vman ethertype 0x8100

create vlan "vlan101"
configure vlan vlan101 tag 101
create vman "vman1"
configure vman vman1 tag 804

configure vlan vlan101 add ports 2 untagged
configure vman vman1 add ports 24 tagged
configure vman vman1 add ports 1 untagged

configure vlan vman1 ipaddress 192.168.1.12 255.255.255.0
configure vlan vlan101 ipaddress 192.168.0.12 255.255.255.0

enable dot1p examination inner-tag port 24

thanks for help (from peter_peter)

Peter, you can only send one untagged vlan inside a VMAN, just as you can add a port as untagged to only one vlan.

The switch has no way of recognizing untagged traffic from different vlans because there's nothing in the packets to help determine whether the traffic belongs to one vlan or the other. (from Daniel_Flouret)

When i attached computer and laptop it works for me, it was some problem with loop on switch.

There is some way to send few untagged vlans via one vman ?

You should try with tagged ports on vlan101, that way it is QinQ (double tags).
I wonder why it didn't work with untagged though. Maybe there is some issue with ARP or FDB, since you are looping ports (same macaddress on both ports). Or maybe there is some issue with vmans and untagged traffic.
