can any one help me to solve this problem?
i have a 3640 cisco router,when i configure nrzi-encoding (under interface mode),it canot be saved
meaning that if for any reason i forced to restart the router the nrzi-encoding was gone and i must reconfigure it again .
although after each time i configure that command
i write the command “write memory” (under privilage mode).
one time i wrote “copy running-config startup-config” but nothing changed.
can anyone help me to make the commandnrzi-encoding saved in nvram ?
thanks for every body
