Step 6
width number
Example:
RP/0/RSP0/CPU0:router(config-stsPath)#
width 3
Configures the number of the STS streams that are concatenated.
The possible values for number are:
• 3—Indicating three STS streams (STS-3c)
• 12—Indicating concatenation of 12 STS streams (STS-12c)
• 48—Indicating concatenation of 48 STS streams (STS-48c)
Widths 3, 12, and 48 are configured on STS paths at natural
boundaries, which coincide with the following path numbers:
• 1, 4, 7, 10, and so on, for STS-3c
• 1, 13, 25, and 37 for STS-12c
• 1 for STS-48c
Note POS interfaces are not supported when width is 1.
Step 7
mode mode scramble
Example:
RP/0/RSP0/CPU0:router(config-stsPath)#
mode pos scramble
Sets the mode of interface at the STS level. Set the mode to pos to
create POS interface (OC12 and OC48 only).
Step 8
root
Example:
RP/0/RSP0/CPU0:router(config-stsPath)#
root
Exits to global configuration mode.
Step 9
interface pos interface-path-id
Example:
RP/0/RSP0/CPU0:router(config)# interface
POS 0/1/1/0
Specifies the POS interface name and notation
rack/slot/module/port, and enters interface configuration mode.
Step 10
encapsulation [hdlc | ppp | frame-relay
[IETF]]
Example:
RP/0/RSP0/CPU0:router(config-if)#
encapsulation hdlc
(Optional) Configures the interface encapsulation parameters and
details such as HDLC or PPP. The default is HDLC.
Step 11
pos crc {16 | 32}
Example:
RP/0/RSP0/CPU0:router(config-if)# pos crc
32
(Optional) Configures the CRC value for the interface. Enter the 16
keyword to specify 16-bit CRC mode, or enter the 32 keyword to
specify 32-bit CRC mode.
The default CRC is 32.
Step 12
mtu value
Example:
RP/0/RSP0/CPU0:router(config-if)# mtu
4474
(Optional) Configures the POS MTU value.
The range is 64–65535.
