Chapter 4 Configuring the Cisco MWR 2941 Router Using the CLI
Configuration Sequence
Configuring In-Band Slave Mode
Step 1 To configure in-band ACR slave mode, you must configure Structure-agnostic TDM over Packet
(SAToP) or Circuit Emulation Service (CES).
• The following example shows how to configure SAToP.
Router(config)# controller e1 0/0
Router(config-controller)# clock source internal
Router(config-controller)# cem-group 0 unframed
• The following example shows how to configure CES.
Router(config)# controller e1 0/0
Router(config-controller)# clock source internal
Router(config-controller)# cem-group 3 timeslots 1-31
Step 2 Enter the following commands to configure the loopback interface.
Router(config)# interface Loopback
Router(config-if)# ip address 10.88.88.99 255.255.255.255
Step 3 Enter the following commands to configure the VLAN interface.
Router(config)# interface Vlan1
Router(config-if)# ip address 192.168.52.10.2 255.255.255.0
Router(config-if)# no ptp enable
Router(config-if)# mpls ip
Step 4 Enter the following command to configure MPLS.
Router(config)# mpls ldp router-id Loopback0 force
Step 5 Enter the following commands to configure the CEM interface.
Router(config)# interface cem 0/0
Router(config-if)# cem 0
Router(config-if-cem)# xconnect 10.10.10.2 7600 encap mpls
Step 6 Enter the following command to configure adaptive clock recovery using a circuit emulation (CEM)
interface:
Router(config)# recovered-clock recovered adaptive cem 0 0 0
Step 7 Enter the following commands to configure the network clock:
Router(config)# network-clock-select 1 PACKET-TIMING
Router(config)# network-clock-select hold-timeout 900
Configuring Out-of-Band Slave Mode
Note When configuring out-of-band clocking, verify that the edge router (such as the Cisco 7600 Series
Router) has matching settings for out-of-band clocking.
Step 1 Enter the following command to configure clock recovery in slave mode:
Router(config)# recovered-clock slave
Step 2 Enter the following commands to configure the loopback interface.
Router(config)# interface Loopback
