11    Tuning the ATM Subsystem

Table 11-1 lists the configuration attributes for tuning the ATM subsystem. Use the sysconfig -q atm command to query the default values. See System Tuning and Performance Management for more information on tuning subsystem operations.

Table 11-1: ATM Configuration Attributes

Attribute Description
resvtimeo The number of seconds after which unused reserved resources are revoked via an ATM_CME_RESV_EXPIRE exception notification. The default is 30 seconds.
sysresvlim The percentage of each driver's total interface bandwidth that is available to constant bit rate (CBR) and pacing circuits in the backward or incoming and forward or outgoing directions. The value is specified as an integer (0-100). Use the atmconfig command to set this limit on a per-driver basis.
fsysresvlim The percentage of each driver's total interface bandwidth that is available to constant bit rate (CBR) and pacing circuits in the forward or outgoing direction. The value is specified as an integer (0-100). Use the atmconfig command to set this limit on a per-driver basis.
bsysresvlim The percentage of each driver's total interface bandwidth that is available to constant bit rate (CBR) and pacing circuits in the backward or incoming direction. The value is specified as an integer (0-100). Use the atmconfig command to set this limit on a per-driver basis.
