 Setting a service category limit to 0 causes the connection requests for the associated service categories 
to be rejected.

To configure the service category limits, use the following global configuration command:

The atm service-category-limit command affects all connections, including those already established.

The following example shows how to change the service category limit for the CBR cells within the 
switch fabric to 3000 cells:

Switch(config)# atm service-category-limit cbr 3000

To display the service category limit configuration, use the following EXEC command:

The following example shows the service category limits configuration:

Switch> show atm resource

Resource configuration:

    Over-subscription-factor 16  Sustained-cell-rate-margin-factor 1%

    Abr-mode:   relative-rate

 Atm service-category-limit (in cells):

         3000 cbr 64544 vbr-rt 64544 vbr-nrt 64544 abr-ubr

Resource state:

    Cells per service-category:

         0 cbr 0 vbr-rt 0 vbr-nrt 0 abr-ubr

The available bit rate (ABR) congestion notification mode changes the type of notification used on ABR 
connections to alert the end station of congestion. ABR mode configuration determines whether ABR 
uses explicit forward congestion indication (EFCI) marking, relative-rate marking, or both, for rate 
management on ABR connections.
