HUAWEI NetEngine80E/40E Router
Configuration Guide - Basic Configurations

9.3.1 Establishing the Configuration Task

Before configuring the router to trace an external BITS clock source, familiarize yourself with
the applicable environment, complete the pre-configuration tasks, and obtain the data required
the configuration. This will help you complete the configuration task quickly and accurately.
Applicable Environment
On a synchronous Ethernet network, if the site where the router is located has a BITS clock, the
router must be set to trace the BITS clock. The router serves as the primary clock to provide a
clock source for the entire synchronous Ethernet network.
There are four types of BITS clocks: 2.048 MHz, 2.048 Mbit/s, 1 pps, and DCLS. You can use
commands to specify the type of external BITS clock source on the clock board.
Pre-configuration Tasks
None.
Data Preparation
None.
9.3.2 Configuring the Lower Threshold of the Clock Signals Output
by the BITS Clock
Context
Do as follows on all routers on the clock synchronization network.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
clock bits output-threshold
The lower threshold (the lowest quality level) of clock signals output by the BITS clock is
configured.

9.3.3 Configuring an External Clock Source and Its Signal Type on
the router
The router supports four types of signals (2mhz, 2mbps, dcls, and 1pps).
Context
Do as follows on every routers on the clock synchronization network.
