ip access-list extended acl
An IP access-list extended (ACL) is a type of access control list used in network security to filter network traffic based on various criteria such as source and destination IP addresses, protocols, ports, and other parameters. It is a more advanced and flexible version of a standard access list that allows more specific filtering of traffic.
Extended ACLs are typically used in routers and firewalls to control access to network resources and to protect against unauthorized access, denial-of-service (DoS) attacks, and other security threats. They can be configured to permit or deny traffic based on specific criteria, and can be applied to inbound or outbound traffic on a network interface or a specific protocol.
Overall, IP access-list extended (ACL) is an important tool for ensuring network security and controlling network traffic.
ip access-list extended from_lan_stock_acl permit ip 10.50.10.0 0.0.0.255 10.50.10.0 0.0.0.255
您创建的 ACL(访问控制列表)名称为 `from_lan_stock_acl`,用于允许从源 IP 地址范围 `10.50.10.0/24` 到目标 IP 地址范围 `10.50.10.0/24` 的流量通过。ACL 配置如下:
```
ip access-list extended from_lan_stock_acl
permit ip 10.50.10.0 0.0.0.255 10.50.10.0 0.0.0.255
```
这个 ACL 规则将允许在 `10.50.10.0/24` 子网内的主机之间的所有流量通过。请注意,这个 ACL 只是一个示例,您可以根据需要进行更改或添加其他规则。
记得在适当的接口上应用这个 ACL,使用以下命令:
```
interface <interface-name>
ip access-group from_lan_stock_acl in
```
其中,`<interface-name>` 是应用 ACL 的接口名称。
请确保根据您的网络需求进行适当的配置和调整。
