Well I've done surfed Cisco on this for a while but still have more questions than answers. To begin with, I don't like VTP because of the potential to screw up the vlan database with a later revision(sequence?) number... So I don't use it in client server mode, only transparrent on the 6513 compressed backbone switch. Many times I will attach hosts to the 6513 by carving out a vlan on that box, which is running native mode. At this point, I want to attach a 3550 switch to one of these vlans. The switch will operate in the same vlan. These are the commands that may be used:
Commands to configure a range of interfaces into a vlan on the 6513:
Router# config t
Router(config)# vlan database
Router(vlan)# vtp transparent
Router(vlan)# exit
Router(config)# vlan 239
Router(config)# interface range fa9/2 - 7
Router(config-if-range)# switchport
Router(config-if-range)# switchport mode access
Router(config-if-range)# switchport access vlan 239
Router(config-if-range)# spanning-tree portfast
Commands to configure an interface into a trunk:
Router# config t
Router(config)# interface fa9/1
Router(config-if)# switchport
Router(config-if)# switchport mode trunk
Router(config-if)# switchport trunk encapsulation isl
Router(config-if)# spanning-tree uplink-fast
Are these commands viable? Will I need to prune in order to prevent this trunk from getting broadcasts from other vlans that are not on this interface? What does DTP buy me? Am I running it? If I specify transparrent mode, will VTP run and therefore will I be able to prune? thx
