ADTRAN 1000R Series data-call [mtu <number>

Command Reference Guide Global Configuration Mode Command Set

data-call [mtu <number> | multilink]

Use the data-call commands to set the pre-authentication defaults for maximum transmit unit (MTU) size

or to enable multilink for inbound demand routing calls. Use the no form of each command to return to the

factory default settings. See the mtu <size> on page 198 for more detailed syntax descriptions.

Syntax Description

mtu <number> Sets the maximum size for the transmit unit. Valid range: 64 to 1520.

multilink Enables the negotiation of multilink MRU size for inbound calls.

Default Values

By default, the MTU size is 1500 and multilink is disabled.

Applicable Platforms

This command applies to the NetVanta 1000R, 3000, 4000, and 5000 Series units.

Command History

Release 11.1 Command was introduced.

Functional Notes

There are certain PPP p arameters that must be known before PPP can negotiate an inbound call when

using demand routing. To ensure PPP convergence, it is recommended (in most cases) that demand

routing interfaces use the same settings as th ose specified in the data-call commands. The dat a -call mtu

<number> command sets the MTU and controls the negotiated maximum receive unit (MRU) size during

incoming calls for link control protocol (LCP) negotiation. If the PPP parameters do not match the

authenticated user, the link is renegotiated.

Usage Examples

The following example specifies an MTU of 1200 on the demand routing interface:

(config)#data-call MTU 1200

The following example enables multilink for inbound demand routing calls:

(config)#data-call multilink
