Set the loopback loopback { local | remote }
mode
Configure the flag { c2 | { j0 | j1 } { sdh |
overhead byte sonet } } flag-value
Set the framing frame-format { sdh | sonet }
format

Set the link type link-protocol { ppp | fr
[ nonstandard | ietf | mfr
interface-number ] | hdlc }
Set the interface mtu mtu
MTU
Set the SD/SF threshold { sd | sf } value
threshold for the
interface

Required
Optional
The default is slave.
Optional
The default is 32 bits.
Optional
Disabled by default
Optional
By default, SDH framing applies.
The default is hexadecimal 16 for C2.
In SDH framing, the defaults are 15
0x0 for both J0 and J1.
In SONET framing, the defaults are
0x01 for J0 and 62 0x0 for J1.
Optional
The default is SDH.
Optional
Enabled by default.
Optional
The default is PPP.
Optional
MTU range and the default value vary
with device.
Optional
If you execute this command with the
value argument set to X, the value of
the threshold specified is 10e-X. SD
threshold defaults to 10e-6 (that is, X
is 6). The SF threshold defaults to
10e-3 (that is, X is 3).
Use the command...
display interface pos
[ interface-number ]
display ip interface pos
[ interface-number ]
display ipv6 interface pos
