I thought I had the vman stuff sorted , in the lab , it works fine.. as per my diagram.
Now the real world.. The layer two internet part is provided by an ISP and their network is cisco.
Configuration as before at both ends
# sh conf | include vmanconfigure vman ethertype 0x8100
create vman "4088"
configure vman 4088 tag 4088
configure vman 4088 add ports 1:47 tagged
configure vman 4088 add ports 1:48 untagged
Connect cable to port 1:48 VMAN( port untagged )
From connecting switch the vlans are tagged..
The only difference now is that the vman terminating switch is an X670 48X
And the user switch is an X670-48T
So basically teh same as the diagram already supplied exect now I am using fibre connections ..
I have added IP addresses to the vman 4088 of 192.168.200.100 and 192.168.20.200.
Ok what can I not do .
I cannot ping the remote end of the vman link ( which as layer 2 I should be able to )
From my client side .. Tagged Vlan out of the switch, connected to the vman untagged port ..
If I send a ping to the default gateway I get no response, though if I look in the arp cache of the PC , I see the default gateway address.
If I have a look at the fdb of the client switch , I can see the mac address of the remote switches ( across the vman )
If I connect my laptop on the client switch and I monitor the Vman ports on the X670-48X I can see the approprate packets coming in on the untagged and going out on the tagged ( as it should be )
Everything look like the lab.. but its not working ..
Any suggestions would be appreciated..
For lab see previous posting with drawing..
