Manage Precision Time Protocol
Precision Time Protocol (PTP, IEEE 1588) is a protocol that enables precise synchronization
of clocks with a sub-microsecond accuracy across a packet-based network. PTP lets network
devices of different precision and resolution synchronize to a grandmaster clock through an
exchange of packets across the network. The switch supports a PTP end-to-end transparent
clock, which is enabled by default, both globally and at the port level.
Note: The switch itself is not affected by PTP.
Manage the Global PTP Settings
By default, PTP is enabled globally on the switch. You can disable PTP to globally, in which
case the switch does not support PTP pass-through.
To configure the PTP end-to-end transparent clock settings globally:
1. Launch a web browser
.
2. In the address field of your web browser
, enter the IP address of the switch.
The login window opens.
3. Enter admin as the user name, enter your local device password,
and click the Login
button.
The first time that you log in, no password is required. However, you then must specify a
local device password to use each subsequent time that you log in.
The System Information page displays.
4. Select System > Management > PTP TC > Global Configuration.
