Hello,


You can configure the 3900 normally i.e.


interface gi 0/0

ip address "address" "mask"

no shut

exit


and configure the switch port as an access port:


int gi 4/1

Switchport access vlan "vlan id"

no shut

exit


In the above configuration, the 3900 will be part of a specific vlan. If you

want to configure the router to be part of multiple vlans, then:


interface gi 0/0

no shut

exit


int gi 0/0.1

encapsulation dot1q 1 native

ip address "address" "mask"

exit


int gi 0/0.2

encapsulation dot1q 2

ip address "address" "mask"

exit


int gi 0/0.3

encapsulation dot1q 3

ip address "address" "mask"

exit



On the switch side:


int gi 4/1

Switchport trunk encapsulation dot1q

Switchport trunk native vlan 1

Switchport mode trunk

exit


In both cases, you can ping the IP of the 4500 from 3900 and vice versa to

check the connectivity.


Hope this helps.

NT
