Configuration Roadmap
The configuration roadmap is as follows:
1.
Configure Switch C as the NTP multicast server.
2.
Configure Switch A and Switch D as the NTP multicast clients.
Data Preparation
To complete the configuration, you need the following data:
l
IP address of each interface
l
Stratum count of the NTP master clock
Procedure
Step 1
Configure the IP addresses of the Switches and ensure that the routes between them are
reachable.The configuration procedure is not mentioned.
Step 2
Configure the IP addresses of the Switches.
Configure the IP address of each interface according to
.
# Configure the IP address of the VLANIF interface on Switch C.
