Just grep for it, you only need to verify that it is there, not isolate it.

Use grep's return status instead of doing things the shell doesn't does 
as well.


if ! ifconfig eth0 | grep -q 00:xx:xx:xx:xx:xx
  then
  echo 'wrong box'
  exit 1
fi

..rest of script..


You could also find this value in /etc/sysconfig/network-scripts/ifcfg-eth0
