Overview of IP Limit
By default, there is no restriction on the user IP addresses that can access a device as long as a user enters the correct username and password. The IP Limit feature restricts user-based IP addresses that can log in to a device. To configure the IP Limit feature, a device must be configured first to reject access from all IP addresses and then configured with the allowed IP addresses.
The configurations of Telnet user access can also be applied to users who are logged in through SSH.
The IP Limit feature improves system security.
