Configuring vman ethertype on EXOS on existing trunk ports

[Bruno_Quintanil]

Hi,

I am configuring vman for our customers. We have a EXOS access switch connected to a S4 (our core switch) switch that will then forward the traffic to another EXOS edge switch.

I found that in order for the traffic traverse the S4 i need to change the ethertype at the EXOS with the following commands:

configure vman ethertype 0x8100 secondary

configure ports 1:50 ethertype secondary

Will this configuration affect the normal switch operation? Being port 1:50 a lag trunk port with regular vlans alerady traversing the S4 switch.

Best regards

 Glad you like it. We have been using this for several weeks now and it seems to be going nicely. ConduentConnect

Hi Bruno,

I'm not positive on this, but I believe that should be OK.

Setting the VMAN ethertype on EXOS tells EXOS which frames are allowed to be associated with a VMAN but it doesn't force all traffic with that ethertype into the VMAN. The Outer Tags would determine if traffic is associated with the relevant VLAN or VMAN. 

A lab test could be a good proof of concept.

Hope that helps!

Thanks Gabriel,

That is what i suspect, just wanted some kind of confirmation.

I have just tested in a lab environment and you are correct, it went all ok. The ethtertype configuration is only applied to vman frames, not affecting normal vlan operations.

Thank you, have a nice day
