we have switches on CatOS 6.4.10 and IOS 12.2.18.
On the 12.2.18 we have only SSH access and on the CatOS 6.4.10, telnet access. We now want to remove the telnet access from all switches and routers. Is there any other way we can connect to these devices apart from telnet. And also how else do we connect to remote devices?
Also is it possible to remove the telnet protocol altogether from all switches and routers because of security reasons?
