Configuring a trusted host for an administrator account

By binding an administrator account to an ACL, you can strictly control the login IP address of the administrator and forbid other non-specified IP addresses to log in to the device.
1. Configure a trusted host for the administrator.
[sysname] acl 2001
[sysname-acl-basic-2001] rule permit source 10.3.0.0 0.0.0.255
[sysname-acl-basic-2001] quit

2. Bind the administrator account named abc to trusted host.
[sysname] aaa
[sysname-aaa] manager-user abc
[sysname-aaa-manager-user-abc] acl-number 2001
