huawei(config)#clock priority system 0
2. Configure the system clock as the transmit clock for an E1 port.
a. Run the interface tdm command to enter the E1 port configuration mode.
b. Run the tx clock or port portid udt system command to configure the system
clock as the transmit clock of the port.
c. Run the display port state command to query the transmit clock of the E1 port.
huawei(config)#interface tdm
huawei(config-if-tdm-)#port 0 udt system
huawei(config-if-tdm-)#display port state 0
---------------------------------------
Port : 0
State : normal
Mode : UDT
Code : HDB3
Looptype : -
Timeslot : -
Clock : system
CRC4 : -
Signaling : -
ESF : -
Impedance : 120 Ohm
---------------------------------------
3. Query configurations and the status of the system clock source.
Run the display clock source command to query configurations and the status of the
system clock source.
huawei(config-if-tdm-)#quit
huawei(config)#display clock source

13.3.5.8 Configuring Congestion Control and Security Policies
This topic describes how to configure global priority-based scheduling policies for queues to
ensure service reliability and configure global security policies to ensure service security.
Context
Congestion control uses queue scheduling technology to map packets sent from the same port
into multiple queues and process packets in each queue based on priority. Congestion control is
recommended.
Security policies cover system security, user security, and service security, which ensure normal
running of services.
