Master:
Switch(config)#ptp clock ordinary domain 0
Switch(config-ptp-clk)#input 1pps 0/0
Switch(config-ptp-clk)#tod 0/0 ?
cisco Set TOD format to CISCO
nmea Set TOD format to NMEA ZDA
ntp Set TOD format to NTP
ubx Set TOD format to UBX
Slave:
Switch(config)#ptp clock ordinary domain 0
Switch(config-ptp-clk)#output 1pps 0/0 ?
offset 1PPS output offset
pulse-width 1PPS output pulse width
Switch(config-ptp-clk)#tod 0/0 ?
cisco Set TOD format to CISCO
nmea Set TOD format to NMEA ZDA
ntp Set TOD format to NTP
ubx Set TOD format to UBX

Configuring a Transparent Clock
Follow these steps to configure the Cisco ME 3600X 24CX Series Switch as an end-to-end transparent
clock.
Note
The Cisco ME 3600X 24CX Series Switch does not support peer-to-peer transparent clock mode.
Configuring Synchronous Ethernet
The following sections describe how to configure synchronous Ethernet timing on the Cisco ME 3600X
24CX Series Switch switch.
Note
Hybrid mode is not supported therefore, network-clock input-source command cannot be configured
with Ordinary Slave mode or Boundary Clock mode.
Command
Purpose
Step 1
Router# configure terminal
Enter configuration mode.
Step 2
ptp clock {ordinary | boundary |
e2e-transparent} domain
domain-number [hybrid]
Configures the router as an end-to-end transparent clock.
Note
Peer-to-peer transparent clock mode is not
supported.
Step 3
Router(config)# end
Exit configuration mode.
