Common System Operations : Using Basic ACL Rules to Control User Login

Latest reply: Apr 14, 2016 07:14:47 1552 1 0 0 0

Hi, everyone! Today I’m going to introduce common system operations: using basic ACL rules to control user login.

After logging in to a device using Telnet or STelnet, you can configure ACL rules to allow only users with the specified IP addresses or on the specified network segments can log in to the device.

The Telnet protocol will bring risks to network security. The STelnet V2 mode is recommended.

The following operation assumes that the user logs in to the device using Telnet or STelnet.

# Configure rules in ACL 2005 to allow only the user at and users on network segment to log in to the VTY interfaces 0 to 4.

<HUAWEI> system-view[HUAWEI] acl 2005[HUAWEI-acl-basic-2005] rule permit source 0   //Allow only the user at to log in to the device.
[HUAWEI-acl-basic-2005] rule permit source   ////Allow only users on the network segment to log in to the device.
