Hi All,
The problem of NULL handler was occuring due to the forward method. In this
method Iface is not defined. If we define it in the method then it gives the
error mentioned. I replaced the Iface with rt_interface and it worked

Prof Ramon, Please correct me if I am wrong.

only looikng at MAC layer). Every time I run the tcl file, I get the exact
same trace file. However, this should not be the case since 802.11 chooses
random backoff value, and, therefore, the trace should be differnt at
