Cat 3550 3560 vlans

Hi,

I beleive these cat switches do layer 3 routing. therefore is it possible to run separate Vlans without the need of a router?

If so has anyone got any documentation on configuring this?

Many Thanks

Hi Johnny,

Yes these switches are layer 3 switches and you can create seperate vlans creating logical interfaces for vlans which are known as SVI interfaces and all the vlans can talk to each other.

Make sure you enable "ip routing"

Make sure whatever layer 3 interfaces you create for vlans you have aleast one trunk to make all those layer 3 vlans active or you have atleast one machine each vlan connected on physical ports to make the layer 3 interface up and up.

Here you go with the link
