Command Mode
Interface configuration
Usage Guidelines
This command first appeared in Cisco IOS Release 11.3 MA.
This command applies to ATM configuration on the Cisco MC3810.
This command is supported on serial ports 0 and 1. The ATM interface must be configured to encapsulation atm-ces, and the vpi/vci must be defined on the interface.

Command Mode
Interface configuration
Usage Guidelines
This command first appeared in Cisco IOS Release 11.3 MA.
This command applies to ATM configuration on the Cisco MC3810.
Using this command, incoming bytes received on a CES port are buffered by the amount configured, and transmitted to the AAL1 process as a block of data.
This command is supported on serial ports 0 and 1 when the encapsulation atm-ces command is enabled.
Example
The following example configures the maximum CES reassembly buffer size to 1520:
