Chapter 10 Cisco IGX 8400 Series IP Service
IP Service—Functional Overview
ATM CoS Service Templates and Qbins on the IGX
The service class templates provide a means of mapping a set of extended parameters. These are
generally platform specific, based on the set of standard ATM parameters passed to the VSI slave in a
UXM port interface during initial bringup of the interface.
A set of service templates is stored in each switch and downloaded to the service modules (UXMs) as
needed during initial configuration of the VSI interface when a trunk or line is enabled on the UXM.
An MPLS service template is assigned to the VSI interface when the trunk or port is initialized. The label
switch controller (LSC) automatically sets up LVCs via a routing protocol (such as OSPF) and the label
distribution protocol (LDP), when the CoS multiple LVC option is enabled at the edge label switch
routers (LSRs).
With the multiple VC option enabled (at edge LSRs), four LVCs are configured for each IP
source-destination. Each of the four LVCs is assigned a service template type. For example, one of the
four cell labels might be assigned to label cos2 service type category.
