may
be changed
to
match
your
network

Selecting
an AlP
Interface
The AlP
interface
is
referred
to
as
atm
in
the
RP
configuration
commands
An
interface
is
created
for each
AlP
found
in
the
system
at reset
time To
select
specific
AlP
interface
use
the interface
atm command
as
follows
interface
atm
where
is
the
slot
number
and
is
the interface
number
Setting the
MTU
Size
To
set
the
MTU
size
use
the following
command
mtu bytes
no
mtu
where
bytes
is
in the range
of
64
through
9188
bytes
and
the default
is
4470
bytes
4470
bytes
exactly

SONET
Framing
In
STM-1
mode
the
AlP
sends
idle
cells
for
cell-rate
decoupling
In
STS-3C
mode
the
AJP
sends
unassigned
cells
for
cell-rate
decoupling The
default
SONET
setting
is
STS-3C
To
configure
for
STM-1
use
the following
command
atm
Bonet
etm-1
To change back
to
STS.-3C
use
the
no
atm
sonet
stm-1
command
Configuring
an
ATM
Interface
for
Local
Loopback
To
configure
an
ATM
interface
for local loopback
useful
for checking
that
the
AlP
is
working
use
the following
command
loopback
pliin
no
loopback
plim
The
no form
of the
command
turns
off
loopback
