Parameters
size
: Specifies the MTU in the range of 128 to 1500 bytes.
Usage guidelines
The MTU setting of a dialer interface affects the fragmentation and reassembly of IP packets.
Examples
# Set the MTU of Dialer 1 to 1200 bytes.
<Sysname> system-view
[Sysname] interface dialer 1
[Sysname-Dialer1] mtu 1200
ppp callback
Use
ppp callback
to enable an interface to initiate or accept callback requests as the callback client
or server.
Use
undo ppp callback
to disable an interface from initiating or accepting callback requests.
Syntax
ppp callback
{
client
|
server
}
undo ppp callback
{
client
|
server
}
Default

Views

Predefined user roles

Parameters
client
:
Enables the interface to initiate callback requests as the callback client.
server
: Enables the interface to accept callback requests as the callback server.
Usage guidelines
The callback client first originates a call, and the server decides whether to place a return call. If a
return call is needed, the callback server disconnects the call and originates a return call according to
the username or callback number.
PPP callback saves costs when the call rates in two directions are different.
Examples
# Enable Serial 2/1/0 to accept callback requests as the callback server.
<Sysname> system-view
[Sysname] interface serial 2/1/0
[Sysname-Serial2/1/0] ppp callback server
