Cisco ATM Services (AXSM) Configuration Guide and Command Reference for MGX Switches
Release 5.2, Part Number OL-6484-01 Rev. C0, September 2005
Chapter 5 AXSM Command Reference
addcon
Routing Parameters
Routing parameter such as maximum route cost (-mc maxcost) or the routing priority (-rtngprio
routingPriority) must be entered only at the master endpoint.
You can assign a priority at the master end of an SPVC or SPVP. The PNNI controller routes higher
priority connections before lower priority connections. The user-configurable range for a connection is,
in descending order of priority, 1–15. The default is 8.
See cnfpri-routing for a detailed description of the Priority Routing feature. Also, the cnfpri-routing
command lets you configure groups of bandwidth so that the order of routing also reflects the bandwidth
requirements of the connection.
A connection created with older software that does not support Priority Routing receives the default
priority of 8 after an upgrade. You can modify this priority by using the cnfcon command.
Frame Discard
The current release supports two types of frame discard for VCCs carrying AAL5 cells. These frame
discard mechanisms are policing-based and congestion-based. Policing-based frame discard depends on
the -frame option in the addcon or cnfcon command. (Congestion-based policing for all cell streams is
governed by settings in the current port SCT.) This -frame parameter is specified only at the master end.
When policing-based frame discard is enabled, the policer discards all cells of an AAL5 frame that
follow a non-compliant cell. Specific actions for PCR and SCR non-compliance are detailed in the
section, “Policer Settings and Consequences.”
When congestion based frame discard is enabled in the current port-level SCT, if the arriving cells
exceed an EPD threshold, the whole frame is discarded.
Note The two types of frame discard are independent of each other and may or may not coexist.
The following list shows the action taken on a connection according to the setting for frame discard. Both
policing-based and congestion-based frame discard are represented. Policing-based discard through
addcon or cnfcon is represented by “A,” and congestion-based discard in the current port SCT is
represented by “B.” A value of 0 means disabled, and a value of 1 means enabled. You can check the
CLP lo/hi and EPD settings for an active, port-level SCT by using the dspportsct command with
parameters cosThr and vcThr.
