Cisco messages can be annoying when you are working a switch that logs ACL rules on a Cisco switch, so something that I’ve found quite useful is editing the line configuration to make the command you are typing in on a Cisco switch be re-printed below the log message.
It’s pretty simple to use, and all you need to do is this, in “configure terminal”.
line con 0
logging synchronous
line vty 0 4
logging synchronous
line vty 5 15
logging synchronous
Another handy tip is enabling SSH. SSH is secure unlike telnet, meaning passwords or important information can’t be seen if an attacker was able to log packets.
SSH is fairly easy to enable, first off make sure you have a username configured or radius, enable the ssh transport under the lines, set a domain-name and then generate some keys.
line vty 0 15
login local
transport input telnet ssh
!
username admin password god
ip domain-name internaluse.net
! out of config mode run
crypto key generate rsa
Make sure you put down 1024 for the RSA keys, other most SSH clients will turn you down.
