Explanation/Reference:
This question is about Cisco IOS Login Enhancements for Virtual Connections feature
which adds the following requirements to the login process:
– Create a delay between repeated login attempts.
– Suspend the login process if a denial-of-service (DoS) attack is suspected.
– Create syslog messages upon the success and/or failure of a login attempt.
These login enhancements are not enabled by default. To enable the login enhancements
with their default settings, you can issue the login block-for command in global
configuration mode. The default login settings specify the following:
– A delay of 1 second occurs between successive login attempts.
– No virtual connection (that is, a connection using Telnet, SSH, or HTTP) can be made
during the "quiet period," which is a period of time in which virtual login attempts are
blocked, following repeated failed login attempts.
