Cisco ATM Services (AXSM) Configuration Guide and Command Reference for MGX Switches

Chapter 5 AXSM Command Reference
cnfcdsct
cnfcdsct
Configure Card-Level Service Class Template—AXSM, AXSM-E, AXSM-32-T1E1-E, AXSM-XG
Assign a service class template (SCT) to an AXSM at the card level. The template contains bandwidth
and policing parameters for an AXSM and an AXSM-E or AXSM-XG.
Note Policing parameters apply only at the port, so specifying SCT 2 or SCT 4 does not provide a card-level
policing function. (As this description states, Cisco provides SCTs 2 and 4 for the card.)
Note Currently, the system does not support certain parameters in the service class templates (SCTs), so you
can specify them through addcon, cnfcon, or Cisco WAN Manager. These parameters are (when
applicable) PCR, SCR, and ICR.
Usage Guidelines
The cnfcdsct command is card-level because it applies to the card’s interface to the backplane. (See
addport for specifying an SCT for a port.) The following characteristics apply to cnfcdsct.
• A valid SCT file must exist on the PXM45 disk before you execute cnfcdsct. To see a list of SCT
files on the disk, execute cd to get to the SCT directory, then execute ls to see the directory named
AXSM.
• You must use cnfcdsct only when the card is down.
• You cannot change the SCT configuration if any ports, lines, or partitions are configured.
• To see the ID of the current SCT, use dspcd for the card-level SCT or dspport for a port-level SCT.
• To see the actual contents of a card-level SCT, use the dspcdsct command.
Background
The node supports a template approach to specifying parameters for large numbers of connections. (If
necessary, you can customize an individual connection by specifying the optional parameters in the
addcon or cnfcon command.) The targets of SCT application are the card itself on the one hand and
logical ports on the other. The cnfcdsct lets you specify an SCT for the card, and the addport command
lets you specify an SCT for a port. You can specify the same or different SCT number for either the port
or card-level, but you definitely need to specify an SCT for each card and port.
Cisco Systems provides SCT numbers 2, 3, 4, and 5. The high-level distinctions between these SCTs are
as follows:
• SCT 2 contains policing parameters, but SCT 3 does not.
• SCT 4 contains policing parameters, but SCT 5 does not.
• If your network design includes eventual configuration of partitions for MPLS, you may need SCT
4 or 5 (or derivations of 4 or 5 that you create through Cisco WAN Manager).
• The AXSM-E and AXSM-XG requires SCT 4 or 5 (for ABR support) and cannot use SCT 2 or 3.
Cisco Systems provides SCTs 2 and 3 with Release 2.0. Additionally, it provides SCTs 4 and 5 with
Release 2.1 Cisco Systems encourages users who have upgraded from 2.0 to 2.1 to use SCT 4 or 5 for
new card and port configurations. For example, if MPLS is implemented, SCT 4 or 5 may be required.
