Configuring Persistent Telnet
This task describes how to configure persistent Telnet on the Cisco ASR 1000 Series Routers.
Prerequisites
For a persistent Telnet connection to access an IOS vty line on the Cisco ASR 1000 Series Router, local
login authentication must be configured for the vty line (the
login
command in line configuration mode).
If local login authentication is not configured, users will not be able to access IOS using a Telnet
connection into the Management Ethernet interface with an applied transport map. Diagnostic mode will
still be accessible in this scenario.
