Chapter 6 Configuring Synchronous Ethernet Monitoring SyncE Command Step 9 show network-clocks Step 10 copy running-config startup config Purpose Verify the configuration. (Optional) Save your entries in the switch startup configuration file. Use the no versions of the commands to disable the REP workaround segment selection or return to the default settings. This example configures the REP workaround and sets the clock input ports: Switch (config)# rep administrative vlan 2 Switch (config)# network-clock-select output 2 SYNCE 0 Switch (config)# interface tengigabitethernet 0/1 Switch (config-if)# switchport mode trunk Switch (config-if)# rep segment 2 Switch (config-if)# exit Switch (config)# ql-enabled rep-segment 3 Switch (config)# network-clock-select 1 SYNCE 0 Switch (config)# network-clock-select 2 SYNCE 1 Switch (config)# interface tengigabitethernet 0/2 Switch (config-if)# switchport mode trunk Switch (config-if)# rep segment 2 Switch (config-if)# exit Switch (config)# network-clock-select mode revert Switch (config)# network-clock-select wait-to-restore-timeout 300 Switch (config)# network-clock-select hold-off-timeout 300 Switch (config)# end Monitoring SyncE Use these privileged EXEC commands to view SyncE configuration on a switch: • show controller BITS Switch# show controller BITS Applique type is T1 Line Coding is B8ZS(Rx), B8ZS(Tx) Framing is ESF(Rx), ESF(Tx) Line Build Out is 0-133ft No alarms detected. • show network-clocks Switch# show network-clocks Network Clock Configuration Input Clock BITS: valid Input Clock SYNCE Te0/1: valid Input Clock SYNCE Te0/2 : valid System Clock Lock Status (T0DPLL) : Locked Output Clock Generated from T4 DPLL T4 DPLL Lock Status : Locked System Clock Selected Ref: Te0/2 T4 DPLL Selected Ref: Te0/1 System Clock (T0 DPLL) Info: Priority Source Type 01 Te0/2 SYNCE OL-23400-01 Cisco ME 3800X and 3600X Switch Software Configuration Guide 6-11
