We currently have all our catos accepting both SSH and telnet sessions . We need to turn off telnet now . For most except our distr. boxes we do not have any permit lists applied. What is required on catos to shut off telnet for both boxes that do currently have a permit list and ones that do not. To shut off on ones that do not have a list I would think you would enable a telnet ip permit command with no permit list applied but I'm not sure and cannot find docs to support this . any help appreciated.
