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 parameters 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 those specified in the data-call commands. The data-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
