Hello.

When I run:

#debug tftp events
TFTP Event debugging is on

#debug tftp packets
TFTP Packet debugging is on

#debug ip dhcp server packet
DHCP server packet debugging is on.

#debug ip dhcp server events
DHCP server event debugging is on.

#debug ip dhcp sip all
DHCP SIP all debugs debugging is on

I observe absolutely anything on the console.

I have not idea why. Can you please give me an idea how to investigate the reason why I cannot observe anything.

Thanks. BR.

Hi Leam2,

 

here replay massage is show normal as well debugging is also starting.

I think you are not shown any log on your terminal(via SSH/Telnet),because "no logging monitor/no logging trap" is configured.

you can check your debugging event/packet/log in "show log". 

 

Hello.
Thank you for your answer.
Below the output of "show log":

Do you know how to increase the number of lines that we get when we run this command?
BR.

Hi Leam2,

 

 

you can increase buffer size using this command "logging buffered <buffer_size> ".
