Hi, you can try this "console (conf)# no logging 172.16.XX.XX level critical"

or you can check "no level critical"

no logging command is until IP address of the host

(config)#no logging 172.16.xx.xx ?

Press enter to execute the command.

my OS version is 6.7.1.20

i still cannot remove the command

switch#no logging traps ?
% Unrecognized command

how do i change the logging command so that all my logs goes to my syslog server ?

switch#no logging traps ?  >> wrong mode and execute command by customer

As I was saying earlier, please get into global configuration mode and run the commands.

i tried switch#(config) no logging traps but level critical still there

exit
logging 172.16.xx.xx
level critical
exit
interface vlan 1

Did you Replace "172.16.xx.xx" with the actual IP address? Also, it could be related to logging severity level.

switch(config)# logging host 172.16.xx.xx

switch(config)# logging level critical

switch(config)# exit

this does not work. 

(config)#no logging 172.16.0.xx level critical  

% Invalid input detected at '^' marker.

if not its a bug or what. level critical is gone.

i tried doing the following 

(config)#logging 172.16.0.xx

(config-logging)#level informational

show run

exit
logging 172.16.xx.xx
exit
interface vlan 1
