You can see that the logon to the vro is successful.Then, we checked the packet capture result of the sniffer tool

Telnet to the Cisco router for remote management is the choice of many network management, but the data transmitted through Telnet is in plain text, so this login method has a great security risk. A malicious user may use a Sniffer tool like Sniffer to perform local monitoring on the Administrator host or an appropriate interface to obtain the Administrator's password for logging on to the Cisoc router. 1.

The user checks network security and requires SSH logon to the core device. Previously, the device used Telnet logon, and the user name and password are transmitted in plaintext, which does not meet the security check requirements. In fact, the SSH login configuration is very simple, mainly divided into the following steps: 1. Configure the Domain Name Sd_core_r7600 (config) # IP domain-name sdcore 2. gener
