Here's a way to get rid of the warnings, but really you need to reconsider the whole approach used in the while loop. That code is a mess.

By declaring lexical variables inside the loop, they get reset each time through. Move the declarations out of the loop for them to persist. 

my (@values1,@val1,@values2,@val2); 
 while (<CMD>) {
 ...

You will still get one warning from line 1, because the code after the if loop is executed for all lines and @val2 is not yet defined. Adding next can fix that. 
my (@values1,@val1,@values2,@val2); 
 while (<CMD>) {
    if ( $_ =~ /PING/ ){
           @values1 = split ;
          @val1 = split(/\(/,$values1[3]); 
         $val1[1] =~ s/\)//;
         next;
           }  
...

Again, while these changes avoid the warnings and hopefully show you why they happened, the entire while loop needs a rethink.
