Hello

series switch and 2 2500 router. After setting my vlan and vtp, I tries to
use trunk command, the switch didn't recognized the command.
2nd Ques: Hw you connect a router to a switch (I'm talking physical
Connection). Hope somebody answer my question.

The command to set trunk on 1900 switch is different from 2500 switch.
CMIIW, in 1900, u can use "trunk on" command to activate trunk on
particular port.

On router, you have to set the proper encapsulation (dot1q or isl)
using commands :
- encapsulation isl <vlan number> OR
- encapsulation dot1q

FYI, I just prepare for my CCNA exam, so this is very text book :p

I Think to be able to set a trunk on a 2500 series router this is only
supported from a certain IOS, and I know older 2500 may not have enough
memory for the updated IOS although you may be able to add more.
