Enabling/Disabling PTP in the Switch

This section lists the CLI configuration steps for enabling/disabling PTP.

CLI Configuration

  1. To enable PTP through CLI, execute the following commands.

    Type the following:

    • Enter the Global Configuration Mode in ISS1.
    iS5comm# configure terminal
    • Enable PTP in the switch.
    iS5comm (config)# no shutdown ptp
    Note:

    This command enables PTP globally and power profile v2 (C37-238-2017) gets configured by default with domain 254, minimum Pdelay Req Interval as 0 i.e. 1 sec, and delay mechanism as peer to peer. The configuration can be verified when command show ptp global info is used (see below).

  2. View the PTP enabled status in the switch.

    Type the following:

    iS5comm# show ptp global info
    PTP System Status
    -----------------
    Global Status : Enabled
    Network Protocol   : IEEE 802.3
    Domain             : 254
  3. To disable PTP through CLI, execute the following commands.

    Type the following:

    • Enter the Global Configuration Mode in ISS1.
    iS5comm# configure terminal
    • Disable PTP in the switch.
    iS5comm (config)# shutdown ptp
    Note:

    This command disables PTP globally and removes all PTP related configuration both in software and hardware. The configuration can be verified when command show ptp global info is used (see below).

  4. View the PTP disabled status in the switch.

    Type the following:

    iS5comm# configure terminal
    % PTP is shutdown

Configuring / Unconfiguring PTP domain

This section lists the CLI configuration steps for configuring / unconfiguring PTP domain.

CLI Configuration

  1. To configure a default PTP domain, execute the following commands.

    Type the following:

    iS5comm# configure terminal
    iS5comm(config)# ptp domain [{ <id (0- 127)> | power-profile }]
    iS5comm(config)# ptp domain 0
    iS5comm(config-ptp)#
  2. View the status of the default PTP domain.

Example 3: Configure PTP without

profile, create a new domain, configure transparent mode and E2E delay mechanism.

    iS5comm(config)# no shutdown ptp 
    iS5comm(config)# no ptp profile

    % PTP domain clock delay mechanism incompatible with profile
    

    Note: 
    Note
that the profile should be compatible with the PTP domain clock delay. In this
case, we will change to defaulte2E as shown below.
