Chapter 1 Overview of the Cisco 3825 Mobile Wireless Edge Router

New Features in Cisco IOS Release 12.4(16)MR1

The sample below configures cell packing for ATM port modes. It specifies a max number of cells as 28 and a cell packing timer as 3,000 microseconds.

The sample below configures cell packing for the N:1 VCC cell relay mode. It specifies a maximum number of cells as 20 and a cell packing timer as 4,000 microseconds.

PVC Mapping

The pw-pvccommand configures PVC mapping or rewrites for PW-configured PVCs. It specifies the PW-side vpi/vci value used in sending and receiving specific PVCs.

The following example illustrates the use of PW packets for the pw-pvccommand:

pvc 0/40 l2transport

encapsulation aal0

pw-pvc 1/40

xconnect 1.1.1.1 40 pw-class l2tp

Asymmetric PWE3

This feature uses two different MPLS enabled IP routes in uplink and downlink directions for creating an asymmetric backhaul path between two Mobile Wireless Routers (MWRs) acting as provider edge (PE) routers.

For ATM over L2TPV3, this feature uses two different IP routes in uplink and downlink directions for creating an asymmetric backhaul path between two MWRs acting as end points for an L2TPV3 tunnel.

No special configuration is needed for this feature apart from configuring the IP routes and having multiple backhaul paths available between two MWRs.

For a configuration example, see the “Asymmetric PWE3 Configuration” section on page B-2in Appendix B.
