Trunk between switches - help

I have two switches crossed two floor as below

5/F 2924XL
4/F 4506

I'm going to create a trunk between two switches, port 1 on both
switches. When I telnet to the 2924 and put below command in, the
switch lost conenctivity immediately. I haven't configured the trunk
port on 4505 yet, is this the problem cause ? If I configure the trunk
port in 4506 then, will the trunk come up immediately. To configure a
trunk port in 4506, should I use the same command ?

int f0/1
switch trunk encapsulation dot1q
switch mode trunk
speed 100
duplex full

As above scenario, configure a trunk port between swithes, I guess the
trunk will be down to update the switching table, what's the expected
downtime for this ?

Re: Trunk between switches - help
Many 2924 issues have been noted with Dynamic Trunking Protocol, DTP.

On the 4506 you may want to use the command "switchport nonegotiate" to
disable DTP.
