Cisco SCTs
Each PXM1E and service module contains default SCT parameters that you can use for communications.
Cisco also supplies additional SCTs that you can use to better support communications. If none of the
Cisco supplied SCTs meet your needs, you can use Cisco WAN Manager (CWM) to create your own
custom SCTs.
This chapter provides information on the Cisco supplied SCTs, describes how to manage the SCTs
available on the switch, and describes how to view the port SCT parameters in use on PXM1E cards.
Note For information on displaying service module SCT parameters, refer to the applicable service module
documentation. For more information on configuring SCTs and SCT parameters, refer to the Cisco WAN
Manager User’s Guide, Release 15.1.
Cisco SCTs
Cisco provides SCTs with the Release 5.1 software. Each SCT is classified by card or service module
type, by whether it is a card or port SCT, and as either policing or non-policing. Although card SCTs
may contain policing parameters, these parameters are ignored. Typically, policing SCTs are used on
UNI ports at the edge of the ATM network and control traffic entering the network. Non-policing SCTs
are typically on trunk ports that interconnect switches within the network.
Note If traffic is properly controlled at the edges of an ATM network, there should be no need for policing
within the network.
Table 7-1 lists the SCTs supplied by Cisco in the Release 5.1 software. For the very latest information
on Cisco SCTs, refer to the following release note documents:
• Release Notes for Cisco MGX 8850 (PXM1E/PXM45), Cisco MGX 8950, and Cisco MGX 8830
