Reducing ITT Fragmentation

It is important to make adjustments to the VC configuration processing, both at initial boot-up and in 
response to interface flaps. Optimal-size ITT blocks will be allocated on the first pass, and eliminate 
fragmentation due to sequentially growing the ITT blocks. 

System and Startup ITT Fragmentation

Two sources of ITT fragmentation are the way that configured connections are installed in hardware 
upon startup and the way they are installed when an interface comes up.

When a startup configuration file is created (e.g. entering the 

write terminal

 command), the PVC 

cross-connect definitions are specified in the file in ascending order by interface, first addressing VPIs, 
and then VCIs (choosing one interface of a PVC as the source). This is the order in which they are 
processed when the system reads the file at startup. If the interface is considered up when the startup 
configuration is read, the VCI values in a VPI are allocated starting with the low values and proceeding 
to the high values; this can result in a series of steps that contribute to the growth of the ITT block used 
by the VPI.

Whether or not interfaces are up at startup, the startup configuration software creates data structures 
representing the PVCs specified in the startup configuration file.

Following a similar procedure, these data structures also order the PVCs by VPI, then VCI, and 
allocations start with the low values and proceed to the high values.

Whenever an interface comes up, connection management software evaluates each of the connections 
defined (in data structures) as residing on the interface, to see whether the connection can be brought up. 
This evaluation also proceeds by VPI, then VCI, and can result in fragmentation due to growth of the 
ITT blocks. 

Solution: Minimum block-size per-VPI

The remedy proposed is to provide hints in configuration for the minimum ITT block size to allocate 
when allocating a block for a VPI on an interface.

Using the minblock Command to Specify a Minimum Block Size

Use the 

minblock 

command to specify the minimum block size for each VPI on an interface. Use the 

force 

keyword to specify a minimum ITT block size if 

autominblock

 mode is not enabled, or to ensure 

that the block size is not overridden by the 

autominblock

 mode. The 

minblock

 command is an interface 

configuration mode command.

Command

Purpose

Step 1

Switch(config-if)#

 

interface slot/subslot/port

Selects the interface to be configured.

Step 2

Switch(config-if)#

 

atm input-xlate-table 

minblock vpi 

vpi-value block-size

 

force

Specifies the minimum block size (as a power of 
2) for a VPI. Use the force keyword.
