Answer / jijiisme
both two mode are administrative mode. just for
administrative purpose only. this mean not really run for
the real because of security reason. I can explain how each
mode work.
dynamic desirable : initiates negotiation messages and
responds to negotiation messages to dynamically choose
whether to start using trunking, and defines the trunking
encapsulation.
I refer this definition form ICND2 book. the simple meaning
is the interface that used "dynamic desirable mode" is
define the encapsulation or protocol ( 802.1q or ISL). ISL
is not support now. so only one 802.1q left. So we can
simply define this mode is leader mode decision maker mode.
ok so the rest mode
dynamic auto : Passively waits to receive trunk negotiation
messages,at which point the switch will respond and
negotiate whether to use trunking, and if so, the type of
trunking.
I also refer this for ICND2 book.
this "dynamic auto" mean follower mode. right, that is
really simple.
when two interface connect one interface must be leader and
another must be follower : this condition is only for
administrative only.
in real word the mode "trunk" and protocol is defined by
admin for security purpose.
