Problems on trunk

[Marius Van Deventer - Umzimkulu]

Hi all

 

I have tried to experiment with trunk (to see how it works) and I get
this problem.

 
I issue the command:
ifconfig trunk0 trunkport pcn0 trunkport pcn1 10.64.15.250 netmask
255.255.254.0


After that I expect my trunk0 to function as a network interface, but it
(and my physical interfaces) can not send or receive anything. If I try
to ping anyone I get the error message: device is busy.

 

Note the unusual subnet. Is this a possible cause? 

I tried to type ifconfig pcn* up for each interface before issuing the
above command but to no avail. 

In any case, what I really need is some more reading material on trunk.
Does anyone have a howto, a case study or any other material I can use
to add to the knowledge I have already gained from the man pages? Google
has made me none the wiser Also let me know if I need to add any info to
this post, dmesg, info on network structure etc.

 

Thanks
Marius
