R0106-HP MSR Router Series Layer 2 - WAN Command Reference(V7)

266
Parameters
client: Enables the interface to send 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 originate 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 interface 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
ppp callback ntstring
Use ppp callback ntstring to configure a dial string for a Windwos NT server to call back.
Use undo ppp callback ntstring to remove the configured dial string.
Syntax
ppp callback ntstring dial-number
undo ppp callback ntstring
Default
No callback dial string is configured.
Views
Dialup interface view
Predefined user roles
network-admin
Parameters
dial-number: Specifies the dial string, a case-sensitive string of 1 to 64 characters.
Usage guidelines
Configure this command on the callback client if the Windows NT server requires PPP callback clients to
send callback numbers.
Examples
# Configure a dial string of 123 45 67 for the Windows NT server to call back.
<Sysname> system-view
[Sysname] interface dialer 1
[Sysname-Dialer1] ppp callback ntstring 1234567
reset counters interface
Use reset counters interface to clear statistics for a dialer interface.
