DETAILED STEPS
Command or Action Purpose
Step 1
configure
Example:
RP/0/RSP0/CPU0:router# configure
Enters global configuration mode.
Step 2
controller sonet interface-path-id
Example:
RP/0/RSP0/CPU0:router(config)# controller
sonet 0/1/1/0
Enters SONET controller configuration submode and specifies the
SONET controller name and interface-path-id with the
rack/slot/module/port notation.
Step 3
clock source {internal | line}
Example:
RP/0/RSP0/CPU0:router(config-sonet)#
clock source internal
Configures the SONET port transmit clock source, where the
internal keyword sets the internal clock and the line keyword sets
the clock recovered from the line.
• Use the line keyword whenever clocking is derived from the
network. Use the internal keyword when two routers are
connected back to back or over fiber for which no clocking is
available.
• line is the default keyword.
Note Internal clocking is required for SRP interfaces.
Step 4
framing sonet
Example:
RP/0/RSP0/CPU0:router(config-sonet)#
framing sonet
Configures the controller for SONET framing. SONET framing
(sonet) is the default.
