Configuration Examples
SONET Controller Configuration Example
The following example shows the commands and output generated when you are performing the
configuration of a SONET controller interface following the steps outlined in the “Configuring a SONET
Controller” section on page 6-3. This example shows the usage of every optional command, along with
listings of options within commands where relevant. An actual configuration may or may not include all
of these commands.
RP/0/0/CPU0:router# configure
RP/0/0/CPU0:router(config)# controller sonet 0/1/0/0
RP/0/0/CPU0:router(config-sonet)# ais-shut
RP/0/0/CPU0:router(config-sonet)# clock source internal
RP/0/0/CPU0:router(config-sonet)# framing sonet
RP/0/0/CPU0:router(config-sonet)# loopback internal
RP/0/0/CPU0:router(config-sonet)# overhead s1s0 2
RP/0/0/CPU0:router(config-sonet)# path ais-shut

RP/0/0/CPU0:router(config-sonet)# report lais
RP/0/0/CPU0:router(config-sonet)# threshold b2-tca 4
SONET APS Group Configuration Example
The following example shows how to configure a two-router SONET APS group:
RP/0/0/CPU0:router# configure
RP/0/0/CPU0:router(config)# aps group 1
RP/0/0/CPU0:router(config-aps)# channel 0 local sonet 0/0/0/1
RP/0/0/CPU0:router(config-aps)# channel 1 local sonet 0/0/0/2
RP/0/0/CPU0:router(config-aps)# interface loopback0
RP/0/0/CPU0:router(config-if)# ipv4 address 172.18.23.169 255.255.255.0
RP/0/0/CPU0:router(config-if)# interface pos 0/0/0/2
RP/0/0/CPU0:router(config-if)# ipv4 address 172.18.69.123 255.255.255.0
RP/0/0/CPU0:router(config-if)# pos crc 32
RP/0/0/CPU0:router(config-if)# keepalive disable
RP/0/0/CPU0:router(config-if)# no shutdown
RP/0/0/CPU0:router(config-if)# interface pos 0/0/0/1
RP/0/0/CPU0:router(config-if)# ipv4 address 172.18.69.123 255.255.255.0
RP/0/0/CPU0:router(config-if)# keepalive disable
RP/0/0/CPU0:router(config-if)# no shutdown
RP/0/0/CPU0:router(config-if)# controller sonet 0/0/0/2
RP/0/0/CPU0:router(config-sonet)# ais-shut
RP/0/0/CPU0:router(config-sonet)# path
RP/0/0/CPU0:router(config-sonet-path)# scrambling disable
RP/0/0/CPU0:router(config-sonet-path)# clock source internal
RP/0/0/CPU0:router(config-sonet)# controller sonet 0/0/0/1
RP/0/0/CPU0:router(config-sonet)# ais-shut
RP/0/0/CPU0:router(config-sonet)# path
RP/0/0/CPU0:router(config-sonet-path)# scrambling disable
RP/0/0/CPU0:router(config-sonet-path)# clock source internal
RP/0/0/CPU0:router(config-sonet)# end
