Step Command Remarks
3. Set the interface description. description text
Optional.
By default, the description of a
POS interface is interface name
Interface, for example, Pos2/1/1
Interface.
4. Set the clock mode. clock { master | slave }
Optional.
The default is slave.
5. Set the CRC length. crc { 16 | 32 }
Optional.
The default is 32 bits.
6. Set the loopback mode. loopback { local | remote }
Optional.
Loopback is disabled by default.
Enable it only when special test is
desired.
7. Configure the overhead bytes.
• flag c2 flag-value
• flag { j0 | j1 } { sdh | sonet }
flag-value
Optional.
• The default is hexadecimal 16
for C2.
• By default, SDH framing
applies. In SDH framing, the
defaults are null for both J0 and
J1.
8. Set the framing format. frame-format { sdh | sonet }
Optional.
The default is SDH.
9. Configure scrambling. scramble
Optional.
Enabled by default.
10. Specify the link layer protocol.
link-protocol { ppp | hdlc | fr [ ietf
| nonstandard ] } Optional.
The default is PPP.
11. Set the interface MTU. mtu size
Optional.
The MTU in bytes ranges from 46
to 10240and defaults to 1500.
The maximum MTU for POS
interfaces is 9216 bytes.
12. Set the SD/SF threshold for
the interface.
threshold { sd | sf } value
Optional.
The SD threshold defaults to 10e-6.
The SF threshold defaults to 10e-4.
13. Set the rate of the POS
interface.
speed speed-value
Optional.
By default, the rate of a POS
interface on a super sub-card is
155 Mbps.
This command is available only on
interfaces of sub-card PIC-TCP8L.
14. Set the link state change delay
for the interface.
link-delay msec milliseconds
Optional.
1000 milliseconds by default.
