c. Click the IRF port bindings link, and then access the details page for IRF-port 2 to assign
XGE 1/0/49 and XGE 1/0/50 to IRF-port 2.
d. Click the advanced link to perform the following tasks:
− Set the domain ID to be the same as Switch A.
The domain ID must be the same across stack member devices.
− If the software version is Release 3111P02, save the running configuration.
If the software version is Release 5103P03, activate IRF port configuration and save the
running configuration.
3. Connect physical interfaces of IRF-port 2 on Switch B to physical interfaces of IRF-port 1 on
Switch A. For more information about connecting IRF ports, see "Stack physical interfaces."
If the software version is Release 3111P02, reboot Switch B.
If the software version is Release 5103P03, Switch B automatically reboots to form a stack with
Switch A.
Verifying the configuration
1. Log in to the Web interface of Switch A.
2. From the navigation tree, select Device > Virtualization > IRF.
3. Access the topology information page to verify the following items:
{ The stack contains member device 2 (Switch A) and member device 3 (Switch B).
{ The stack ports are connected.
NTP configuration example
Network requirements
As shown in Figure 15:
• Configure the local clock of Device A as a reference source, with the stratum level 2.
• Set Device B to client mode and use Device A as the NTP server for Device B.

Configuration procedure
1. Configure Device A (NTP server):
a. From the navigation tree, select Network > Service > NTP.
b. Enable the NTP service.
c. Specify the IP address of the local clock as 127.127.1.0.
d. Configure the stratum level of the local clock as 2.
2. Configure Device B:
a. From the navigation tree, select Device > Maintenance > Settings.
b. Access the date and time page to select automatic time synchronization with a trusted time
source, and then select NTP as the time protocol.
c. Specify the IP address of Device A as 1.0.1.11, and configure Device B to operate in server
mode.
