Step Command Remarks
3. Configure the interface
description.
description text
By default, the description of a
POS interface is interface name
Interface, for example, Pos2/2/0
Interface.
4. Set the keepalive interval.
timer-hold seconds The default setting is 10 seconds.
5. Set the clock mode.
clock { master | slave } The default setting is slave.
6. Set the CRC length.
crc { 16 | 32 } The default setting is 32 bits.
7. Set the loopback mode.
loopback { local | remote } By default, loopback is disabled.
8. Configure the overhead bytes.
• Configure the C2 path signal
label byte:
flag c2 flag-value
• Configure the J0 regenerator
section trace byte:
flag j0 { sdh | sonet } flag-value
• Configure the J1 path trace
byte:
flag j1 { sdh | sonet } flag-value
By default:
• The C2 byte is 0x16.
• The system uses the SDH
framing format.
• In SDH frames, both J0 and J1
bytes are empty strings.
9. Set the framing format.
frame-format { sdh | sonet } The default setting is SDH.
10. Enable payload scrambling.
scramble
By default, payload scrambling is
enabled.
11. Set the data link layer protocol.
link-protocol { hdlc | ppp } The default setting is PPP.
12. Set the MTU.
mtu size The default setting is 1500 bytes.
13. Enable interface dampening
on the interface.
dampening [ half-life reuse
suppress max-suppress-time ]
By default, interface dampening is
disabled on POS interfaces.
14. Configure the expected
bandwidth of the interface.
bandwidth bandwidth-value
By default, the expected
bandwidth (in kbps) is the interface
baud rate divided by 1000.
15. Restore the default settings for
the POS interface.
default N/A
16. Shut down and bring up the
interface.
shutdown
undo shutdown
By default, a standard POS
interface is up.
For the settings to take effect, you
must perform this step.
If no cable is connected to the
interface, shut down the interface
to prevent interface exceptions.
