VLAN ID (VID) Tag Nesting.  
Another related enhancement provides support for nested 802.1Q tags by 
allowing a tag push or tag pop attribute to be associated with a VID. The push attribute indicates that a 
new tag is to be added to the frame, while the pop attribute indicates that the top-level tag is to be 
removed from the frame. This capability is augmented by an option that allows the 802.1p priority of 
the frame to be either preserved or set to a user-configurable value when a new tag is pushed. These 
functions make it possible for service providers to tunnel customer-specific VLANs across a common 
ATM backbone in a very simple manner.
VLAN to PVC Mapping.  
VLAN to PVC mapping can be used by service providers to isolate and 
provision a customer’s traffic using different VLANs and PVCs for each customer. Thus, a service 
provider can securely transport a customer’s Ethernet traffic across an ATM backbone or vice-versa. 
Software Requirements 
The ATM module requires that you run ExtremeWare 7.0 or later on both the MSM64i module and the 
ATM module, BootROM 7.8 for the MSM64i module, and BootROM 1.18 for the ATM module.
For more information about software requirements and ATM module configuration, see the ExtremeWare 
Software User Guide 
and the ExtremeWare Command Reference Guide
Hardware Requirements
The ATM module is compatible with “i” series MSM modules only. For the most current list of I/O 
modules supported for use with the ATM module, consult your release notes.
ATM modules installed in a BlackDiamond chassis require at least one BlackDiamond Ethernet I/O 
module also installed in the chassis in order to operate correctly.
