Parameter template is an efficient, fast, and easy-to-maintain way to add rules in security groups. For example, when you need to add multiple IP ranges, specified IPs, or protocol ports of multiple types, you can define a parameter template. You can also use the parameter template subsequently to maintain the IP sources and protocol ports in the security group rules.
All the IP addresses and protocol ports in this document are examples. Please replace them according to your actual business conditions during configuration.
Suppose you want to configure the following security group rules and need to update the inbound source IP range and protocol port later:
Rejected target IP address: 192.168.10.4; protocol port: TCP:800
Because you have the same security group policy for multiple IP ranges and protocol ports, and you need to update the source IP range later, you can use a parameter template to implement the addition and maintenance of security group rules.
Suppose you need to add an inbound rule with the IP source being the
10.0.1.0/27 IP range and the protocol port being
UDP:58. You can directly update the parameter templates of the IP address
ipm-0ge3ob8e and the protocol port
10.0.1.0/27IP range in a new line and click Submit.
UDP:58inbound protocol port in a new line and click Submit.
