Trunking question

Hi there,

I am a newbie so forgive my ignorance. I have come acroos 5 switches (3550's) that are all daisy chained via their gig ports. I am going to introduce 3 new vlans as there is only vlan 1. Would and could i trunk the gig ports to allow the vlan traffic to traverse the switches to the router or would i trunk fa ports?

Sorry if this is a dumb question, but hey i didn't say i was bright :)

Thanks for any help.

Regards Andrew.

Are you sure they are not already trunking? 3550's in their default configuration will form trunks with each other, Do a show interface trunk command to see if you have interfaces trunking and what VLANs are allowed on the trunks.
