Chapter9 Configuring Resource Management
Configuring Global Resource Management
Example
The following example shows how to configure ATM threshold group 5 with a maximum number of cells
before the cells are discarded:
Switch(config)# atm threshold-group 5 max-cells 50000
Displaying the Threshold Group Configuration
To display the threshold group configuration, use the following user EXEC command:
Example
The following example displays the threshold group configuration:

Step7 Switch(config)# atm threshold-group
[module-id module]1 group max-cells number
Configures the maximum number of cells queued
for specified threshold group for all module-ids.4
Optionally, configure for the specified threshold
group for the specified module-id.
Step8 Switch(config)# atm threshold-group
[module-id module]1 group marking-threshold
percent
Configures the threshold of per-connection
queue-full at which the queue is considered full
for EFCI marking and ABR relative-rate
marking.
1. The module-id identifier is only supported on the Catalyst8540 MSR.
2. CLP = cell loss priority.
3. EPD = early packet discard.
4. Each module on the Catalyst8540 MSR has its own cell memory and threshold groups. There are eight of these modules in
a 20-gigabyte configuration. Each module has a 64-kbps cell memory, and the threshold groups can be configured per
module. By default, all the threshold groups of all the modules are configured identically.
