Chapter7 Configuring Virtual Connections
Input Translation Table Management
The CLI-specified non-force minblock interface configuration command is overridden when one or
more of the following four conditions are present:
When the minblock command is processed and the existing PVCs on the interface are sufficient to
require, at a minimum, the block size specified in the CLI command. (Under these circumstance, the
block size is subsequently determined by analysis, rather than the CLI value.)
When a VC is added to the interface/VPI referred to by the CLI command, and requires, at a
minimum, the block size specified in the CLI command. (Under these circumstances, the block size
is subsequently determined by analysis).
When a VC is deleted from the interface/VPI referred to by the CLI command. (Under these
circumstances, the block size is subsequently determined by analysis .
When a nonvolatile-generation operation is performed (e.g. initiated by entering the write terminal
command).
Using the Autominblock Command to Enable the Minimum Mode
Use the autominblock command to enable the automatic analysis of minimum ITT needs of each
interface/VPI in the system. The system uses this information for a subsequent ITT request, and specifies
minimum block sizes in startup configuration generation via the in sertion of minblock commands. This
is a global configuration mode command.
Step3 Switch(config-if)# atm input-xlate-table
minblock vpi vpi-value block-size force
Repeats this command for as many VPIs are
required.
Step4 Switch(config-if)# exit Returns to global configuration mode.
