A Short guide to locking down a fresh switch
Enable SSH
configure terminal |
crypto key generate ssh |
ip ssh |
no telnet |
Time Servers
sntp server x.x.x.x |
alternatively: sntp server priority 1 x.x.x.x |
sntp unicast |
sntp 720 |
timesync sntp |
Logging and other services depend on accurate timestamping, Procurve can use standard NTP sources and Windows DCs
TFTP, SFTP & SCP
ip ssh filetransfer |
enable sftp & scp |
no tftp server |
no tftp client |
Management VLAN
management-vlan x |
can be either VLAN number or name |
ip authorized-manager x.x.x.x mask x.x.x.x operator/manager |
Locks down the Management functions of the switch, allowing access from the nominated VLAN only, it also Disables routing to the management VLAN

RADIUS
radius-server host x.x.x.x key Super$ecretRadiusK3y |
aaa authentication X login radius local |
X can be console, telnet, ssh or web |
aaa authentication X enable radius local |
aaa authentication num-attempts N |
aaa authentication login privilege-mode |
optional to allow operator or manager access as per RADIUS response |
Options configure switch to contact RADIUS for logon to switch console or webinterface, and optionally via enable to use L15/Manager commands.
If no RADIUS server is contactable, switch will fall back to using local authentication table
Physical Security
no front-panel-security password-clear |
no front-panel-security factory-reset |
Somewhat dangerous commands if you forget the local password
