Configuring the ATM Interfaces 63
The parameters used to configure these interfaces are reviewed in the
following configuration examples, and they are also listed in the
configuration file example in Appendix H. The example ASCII
configuration templates are provided on the Enterprise OS 11.3.1
documentation CD-ROM for you to modify to meet the requirements of
your installation. Also see Appendix H for a copy of these configuration
templates.
To configure PVCs (MPATM), follow these steps:
There are 14 predefined traffic shapers available for the PVC. Traffic
shaper 1 is the default traffic shaper. The traffic shaper parameters (peak
rate, average rate, burst) can be reconfigured in the ATM service if
required.
1 Reconfigure traffic shapers using:
SETDefault -ATM TrafficShaper = <shaperid> <peak> <avg> <burst>
[High | Low]
2 Configure the virtual circuit identifier (VCID) using:
ADD !<vport> -ATM PermVirCircuit <vcid> <vpi>.<vci> [ LLCSNAP | [
NULL IP | IPX | PPP ] ] [<shaperid>]
A PVC requires the association of a unique virtual circuit identifier (VCID)
to the ATM service provider’s VPI.VCI. The PVC supports either LLCSNAP,
NULL IP or NULL IPX encapsulation. A MPATM virtual port can be
configured with multiple PVCs.
3 Configure the virtual port as MPATM using:
ADD !<vport> -POrt VirtualPort <path> MPATM
The virtual port owner must be configured as MPATM. All PVCs
configured for the <vport> are bound to the virtual port. Data received
on the PVC will be tagged as received on the virtual port.
To configure LAN Emulation, follow these steps:
1 Set LAN Emulation on a virtual port using:
SETDefault !<vport> -ATMLE ElanName = ÒstringÓ
Each emulated LAN is configured on one virtual port.
2 Configure the virtual port as either Ethernet LAN Emulation or Token Ring
LAN emulation using:
ADD !<vport> -POrt VirtualPort <path> ETHATM
ADD !<vport> -POrt VirtualPort <path> TRATM
