ASR903-R1 Configuration
interface GigabitEthernet0/1/1
! description to R3
synchronous mode ! enable sync-e under interface
!
interface GigabitEthernet0/1/0
description to R2
synchronous mode
network-clock synchronization automatic ! enable clock selection
algorithm
network-clock synchronization ssm option 1 ! to select E1 or T1 type
network-clock synchronization mode QL-enabled ! use Qualiy enabled mode
network-clock input-source 10 External R0 e1 crc4 ! BITS clock as source
network-clock wait-to-restore 30 global
esmc process ! enable ESMC process
ASR903-R2 Configuration
interface GigabitEthernet0/1/0
! description to R1
synchronous mode ! enable sync-e under interface
!
interface GigabitEthernet0/1/2
