Quick note about setting the telnet timeout timer. I dont recommend doing this, but if you need to for some reason, here is how to configure it where it wont kick you off after the timeout value expries.
telnet@BHMCore1(config)#telnet timeout ?
DECIMAL <0..240> In minutes, 0 never timeout
telnet@BHMCore1(config)#telnet timeout 0
telnet@BHMCore1(config)#exit
telnet@BHMCore1(config)# no telnet server
ReplyDeletetelnet@BHMCore1(config)# crypto key zeroize rsa
telnet@BHMCore1(config)# crypto key zeroize dsa
telnet@BHMCore1(config)# crypto key generate rsa mod 2048
telnet@BHMCore1(config)# ip ssh authentication-retries 2
telnet@BHMCore1(config)# ip ssh timeout 30
telnet@BHMCore1(config)# ip ssh idle-time 30
telnet@BHMCore1(config)# ip ssh scp disable
telnet@BHMCore1(config)# ip ssh encryption disable-aes-cbc
telnet@BHMCore1# sh ip ssh
