sw2950_02(config-if)#switchport nonegotiate
first, DTP (dynamic trunking protocol) is cisco proprietary and will not work with gray market switches... use nonegotiate in a mixed environment... this disables DTP, will only become a trunk with ON or NONEGOTIATE ports, and port ranges are not allowed with this command
sw2950_02(config)#int fa0/2
sw2950_02(config-if)#sw mode trunk
trunking is on... DTP signals are sent to the other connected port to initiate trunking if it is ON, AUTO, or DESIRABLE
if:
sw2950_02(config-if)#sw mode dynamic desirable
the port will become a trunk after detecting DTP signals of ON, AUTO or DESIRABLE from the connected port
if:
sw2950_02(config-if)#sw mod dyn auto
the port will become a trunk if the other port is ON or DESIRABLE
if:
sw2950_02(config-if)#no sw mod trunk
trunking and DTP are disabled and this is the desired state for access ports; no dynamic establishments can occur

OZLAN...
the last day and a half has been enlightening... i used to support a large cisco network for many years, and the needs of that community... those needs were not my needs but i still had some great experiences... having my own equipment and doing with it exactly as i want allows unlimited freedom... there is only so much experimentation one can do under production circumstances...
i have my 2950's and 2620's currently running rip and communicating with each other and the internet... i'll soon move on to ripv2, eigrp, ospf, etc... i have vlans for hosts and printers, trunks are up and running, serial connections are singing, and i couldn't be happier... also, if you have a chance to get your hands on a 3550 or 3560, beg borrow or steal...
this is a new phase for me, and as i move to different protocols with OZLAN and make new configurations, i'll erase start on all the devices, and rebuild them as if it was all new again... and you will all feel the pain with me...

my plan...
i am setting up a lab comprised of 3 2610xm routers, a 3550 layer 3 switch, 2 2950 switches and all the cables... basically, a ccnp lab in which i will share lab experiences, lab set ups and anything else i bump into along the way... all things useful that i find towards a certification end, i will post... i will continue to share networking experiences i've had over the past twenty years, as well as any tips or help i may be able to provide... test questions, labs, trial and error, etc...
a word on braindumps... don't waste your time... trust in the materials within your reach... do it legitimately and it will be worth it in the end... there are no shortcuts...
please post any and all comments or suggestions and feel free to email any time... any difficult areas you might have with study materials, test questions, et al...
this will help me in my quest, and hopefully, this will help in yours...
