R2511-HP MSR Router Series Layer 2 - WAN Command Reference(V5)

182
Field Descri
p
tion
Cause
Cause of a DOWN physical link. If the port has been shut down with the
shutdown command, this field displays Administratively. To restore the
physical state of the interface, use the undo shutdown command.
interface dialer
Use interface dialer to create a dialer interface. In C-DCC, this equals creating a dialer circular group.
Use undo interface dialer to remove a dialer interface.
Syntax
interface dialer number
undo interface dialer number
Default
No dialer interface is created.
Views
System view
Default command level
2: System level
Parameters
number: Dialer interface number in the range of 0 to 1023.
Usage guidelines
The dialer interface has a fixed baudrate of 64000 bps.
In C-DCC, you can assign multiple physical interfaces to a dialer interface to inherit the attributes of this
dialer interface by assigning them to the dialer circular group for the dialer interface with the dialer
circular-group command. This is efficient where calling multiple destinations simultaneously is desired,
because instead of configuring individual physical interfaces, you only must configure multiple dialer
routes on the dialer interface.
In RS-DCC, any dialer interface can use the services provided by multiple physical interfaces, and
individual physical interfaces can provide services for multiple dialer interfaces at the same time.
Therefore, authentication must be configured on these physical interfaces, so as to use the username of
a dial-in party to locate the corresponding dialer interface for the call. In this mode, physical interfaces
and dialer interfaces are dynamically bound. Furthermore, a dialer interface can only call a destination
address as specified in the dialer number command.
The physical interfaces in C-DCC and Resource-Shared DCC do not use individual network addresses.
Instead, they use the addresses of the corresponding dialer interfaces.
In both C-DCC and RS-DCC, physical interfaces use the network addresses of their associated dialer
interface rather than being assigned separate addresses.
