[ns] more than 8 bits for portaddr with ns2.1b5

["Francesco Lo Presti" <lopresti@research.att.com>]

Hi

I am using ns-2 (ns2.1b5 to be precise) and I was trying to have more than
255 ports per node. Without uprgrading (for the moment) to the newer version
which I understand support 32 bits port address, I was trying (without
success) to make it work with my actual version.

I am using the following command

set ns [new Simulator -multicast on]
Node expandaddr
$ns multicast
$ns set-address 15 16

(and also tryied $ns set-address-format expanded in place of Node
expandaddr) and I always get the following

# of agents attached to node _o193 exceeds port-field length of 255 bits
    while executing
"error "\# of agents attached to node $self exceeds port-field length of
$mask bits\n""
    (procedure "_o193" line 10)
    (Node attach line 10)
    invoked from within
"$node attach $agent"
    (procedure "_o7" line 2)
    (Simulator attach-agent line 2)
    invoked from within
"$ns attach-agent $node(34) $mon_23_245"
    (file "sim.tcl" line 3301)

To me, it seems the port bits are not increased to 16. I guess I am doing
something wrong, but I do not know exactly what.

thanks in advance for any help

Sincerely
