Configuring ATM Virtual Path Shaping on ATM MICs with SFP
Starting in Junos OS Release 14.2, on MX Series routers with Modular Port Concentrator (MPC) interfaces and an ATM Modular Interface Card (MIC) with small form-factor pluggable transceiver (SFP) installed, you can configure class-of-service (CoS) hierarchical shaping and schedule for the traffic carried on an ATM virtual path (VP).
After you configure the ATM physical interface and logical interface
units, you must configure an interface set that consists of the ATM
logical interface units. You then define one or more CoS traffic control
profiles that includes the ATM service category (atm-service) and the peak cell rate (peak-rate), sustained cell rate
(sustained-rate), and maximum burst size (max-burst-size) parameters. Finally, you apply the specified traffic control profile
to the output traffic at the interface set and at its member ATM logical
interface units.
To configure ATM VP shaping for traffic on an ATM MIC with SFP:
The following example configures ATM VP shaping on interface
at-1/0/4 with VPI 40. The example defines an ATM interface set
named atm-vp-ifset with two member ATM logical interfaces, at-1/0/4.50
and at-1/0/4.51, both of which use VPI 40. Traffic control profiles
atm-vp-tcp1, atm-vp-tcp2, and atm-vp-tcp3 are each defined with the atm-service, peak-rate, sustained-rate, and max-burst size cell parameters. Finally, the output-traffic-control-profile statement applies traffic control
profile atm-vp-tcp1 to the output traffic at interface at-1/0/4.50,
atm-vp-tcp2 to the output traffic at interface at-1/0/4.51, and atm-vp-tcp3
to the output traffic at the atm-vp-ifset interface set.
