ces connect atm-interface pvc [name | [vpi/]vci]
no ces connect atm-interface pvc [name | [vpi/]vci]

Syntax Description

atm-interface

Number of the ATM interface. The only valid option on the Cisco MC3810 is ATM0.

pvc

Specifies that the connection is to an ATM PVC.

name

(Optional) The name of the ATM PVC.

vpi/

(Optional) The virtual path identifier value.

vci

(Optional) The virtual channel identifier value.

Default

No ATM interface is defined.

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.

Example

ces initial-delay

To configure the size of the receive buffer of a CES circuit, use the ces initial-delay interface configuration command. Use the no form of this command to remove the initial-delay value.

ces initial-delay bytes
no ces initial-delay bytes

Syntax Description

bytes

The size of the receive buffer of the CES circuit. The valid range is from 1 to 16,000 bytes. This command is used to accommodate cell jitter on the network. Bytes received from the ATM network are buffered by this amount before being sent to the CES port.

Default

4000 bytes

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.

Example

The following example configures the transmit buffer of the CES circuit to 8000 bytes:

ces initial-delay 8000

ces max-buf-size

To configure the transmit buffer of a CES circuit, use the ces max-buf-size interface configuration command. Use the no form of this command to delete the CES transmit buffer size.

ces max-buf-size size
no ces max-buf-size size

Syntax Description

size

Maximum size of the transmit buffer for the CES. Possible values are from 80 to 1520. The default is 256.

Default

256

Command Mode

Interface configuration

Usage Guidelines

This command first appeared in Cisco IOS Release 11.3 MA.

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:

ces max-buf-size 1520

ces partial-fill octet
no ces partial-fill octet

Syntax Description

octet

Number of user octets per cell for the CES. Possible values of octet range from 0 to 47. Setting this number to zero disables partial cell fill and causes all cells to be completely filled before they are sent.

Default

47

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.
