Configuring Global Resource Management
Caution 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:
Note The atm service-category-limit command affects all connections, including those already established.
Example
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
Displaying the Service Category Limit Configuration (Catalyst 8510 MSR and LightStream 1010)
To display the service category limit configuration, use the following EXEC command:
Example
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
Configuring the ABR Congestion Notification Mode (Catalyst 8510 MSR and
LightStream 1010)
The available bit rate (ABR) congestion notification mode changes the type of no tification 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.
Command Purpose
atm service-category-limit {cbr | vbr-rt |
vbr-nrt | abr-ubr} value
Configures ATM service category limits for a
specific output queue.
Command Purpose
show atm resource Displays the service category limits
