Palo Alto Networks: Console terminal got overlapping output

When I first trying to test Palo Alto Networks firewall through its console interface I encountered an annoying problem, that is I got overlapping and confusing outputs when I issued commands.

The default terminal type used by Palo Alto Networks Firewall is VT100, however most of the time we are using xterm. You can change the terminal type from the CLI:

admin@PA-5050> set cli terminal type xterm

After the terminal type is chosen, restart PuTTY again.

To verify the cli settings either use:

admin@PA-5050> show cli info

User                    : admin
Process ID              : 3240
Pager                   : enabled
Config Display Format   : default
Vsys configuration mode : disabled

admin@PA-5050>

Or use:

admin@PA-5050> debug cli detail

The set command in operational mode does not need to commit, the change will take immediate effect.
