Uplinking to vlan switch

[GaZZaW]

Recently I have been adding switches (2900xl and 3550)to our backbone vlan switch (catalyst 2926).
I usually just use a cross cable into vlan port (for example vlan 20) and leave the 2900 as vlan1.
I dont configure anything exept for ip and default gate as all ports are just for workstation use.(except uplink of course)so no trunk ports configured.
Should I configure vlan 20 on the workgroup switch?
should I use uplinkfast?
Would this make anydifference in network performance?
Am I forgeting anything ??
Where could i find something about best practices for vlan networks.

Thanks

You should use the 3550 as the backbone switch, and configure the "uplink" ports a trunks. With this you can then setup the 3550 to be a VTP server and the remaining switches as VTP Clients. When you add vlans to the server, the clients will receive the configuration.

Then if you wanted to have VLAN 20 on a different switch, all you would have to do is configure that port for that vlan. The vlan would already be defined since the switch learned it from VTP.

It is important to make the "uplink" ports trunks on both ends of the switches so the layer3 3550 switch will do the routing for all the switches.
